    Description
    Title of the invention: INDUSTRIAL EQUIPMENT FOR COOLING A FUSED METAL Technical Field [0001] The present invention relates to industrial equipment having the function of cooling a molten material, such as a metal.
    PRIOR ART [0002] In factory equipment or the like for treating a metal, an operation is carried out to cool a molten metal at high temperature by exposing the molten metal to the atmosphere or by immersing the molten metal in a refrigerant stored in a cavity. For example, a technique for accelerating the diffusion of molten material in water and improving a cooling effect is described in Japanese Unexamined Patent Application, the first publication 2010-266286.
    When a high temperature molten material is immersed in a cavity or the like in which a refrigerant is stored, since the molten material spreads freely on a floor surface, the contact range with the refrigerant is enlarged, and a coarse mixing phenomenon (atomization of the molten material) is favored. Therefore, in some cases, there may be a rapid boil, and countermeasures to prevent this are necessary.
    The present invention has been made taking into consideration the above circumstances, and an object of the present invention is to provide industrial equipment capable of preventing the acceleration of the coarse mixing phenomenon when a metal in high temperature melting is cooled, and able to suppress the rapid boiling of water.
    Disclosure of the invention (1) According to one aspect of the present invention, industrial equipment comprises:
    a cavity configured to store a refrigerant; and a cooling acceleration device which is housed in the cavity and is placed in the refrigerant stored in the cavity, wherein the cooling acceleration device comprises: a passage forming part in which a tubular passage extending in a horizontal direction is formed; and an introduction part configured to introduce the molten material immersed in the cavity, in the passage forming part.
    (2) In the industrial equipment described in section (1), the industrial equipment further comprises a container configured to drop drops of molten material, in which the cavity is positioned under the container, the cooling acceleration device is housed in the cavity and is below the container, and the molten material which has fallen from the container into the cavity is introduced into the passage forming part via the introduction part.
    (3) In industrial equipment described in section (1) or (2), a surface of a cross section of the passage forming part which is parallel to a lower surface of the forming part of passage, may be 2000 mm 2 or greater and 20,000 mm 2 or less.
    (4) In industrial equipment described in any one of headings (1) to (3), in a cross section of the passage forming part perpendicular to its direction of extension, a horizontal length of the cross section can represent from 1 to 200 times a vertical length of the cross section.
    (5) In the industrial equipment described in section (2), the introduction part can be a through hole formed in a side wall of the passage forming part facing the container.
    (6) In industrial equipment described in section (5), a plurality of through holes can be formed in order to be aligned in the direction of extension of the passage forming part.
    (7) In industrial equipment described in any one of headings (1) to (6), a plurality of passage forming parts can be installed in industrial equipment in order to be aligned side by side. rib in the direction of its width.
    (8) In industrial equipment described in any one of headings (1) to (7), the plurality of passage forming parts can be stacked in the vertical direction.
    (9) In industrial equipment described in any one of headings (1) to (8), a ceiling part of the passage forming part can be provided with a plurality of projections formed in the inside the passage training part.
    (10) In industrial equipment described in any one of the headings (1) to (9), a floor part of the passage forming part can be provided with a projection formed inside the passing training part.
    (11) In the industrial equipment described in any one of the headings (1) to (10), a covering element can be installed on top of the passage forming part existing at the position highest in the vertical direction.
    (12) In industrial equipment described in any one of headings (1) to (11), a projecting part can be formed on top of the passage forming part existing at the position highest in the vertical direction.
    As described above, the industrial equipment according to the present invention is configured so that the molten material falls in a tubular passage storing the refrigerant. After the falling of the molten material, a space surrounded by the side walls of the passage is in a state in which the molten material collects in the lower area of the space, and water collects on the upper area from space. In this case, since the diffusion of the molten material in the horizontal direction is limited, a contact area of the molten material with water is less important than in the case in which the same amount of molten material does not is not accommodated in the passage and spreads to spread over the floor surface. Consequently, it is possible to reduce the ratio of a part of the molten material, which comes into contact with water and coarsely mixes with it, compared to the other part of the molten material housed in the passage. , and thus the rapid boiling of water can be suppressed.
    In addition, in industrial equipment according to the present invention, since the molten material is housed in the narrow space in the passage, the heat of the molten material is maintained in the passage, and the temperature of the water stored in the same space rises quickly. Therefore, the interior of the passage is in a state rich in vapor, and the generation of new water vapor which is a cause of generation of shock wave, does not occur easily, and therefore, the boiling Rapid water can also be removed.

    Detailed description of the invention Below, the industrial equipment according to an embodiment to which the present invention is applied, is described in detail with reference to the drawings. In the drawings used in the following description, for the sake of facilitating the understanding of the characteristics, there are cases in which characteristic parts are illustrated for enlargement for the sake of convenience, and the dimensional ratio of each component is not necessarily the same. same as the real report. In addition, the materials, dimensions and the like illustrated in the following description are examples, but the present invention is not limited thereto, and can be carried out with the appropriate changes for a purpose which does not change its substance.
    First embodiment [0033] Figure 1 is a sectional view of the industrial equipment 100 according to a first embodiment of the present invention. The industrial equipment 100 comprises a container 101 in which a molten material M such as a metal is stored, a cavity 102 which is positioned below the container 101 and in which a refrigerant W such as water is stored, and a cooling acceleration device 103 which is housed in the cavity 102 to be below the container 101 and positioned to be placed in the refrigerant W stored in the cavity 102.
    The container 101 is configured so that the molten material M stored in the cavity 102 can fall outside of the latter. Although a shape of the container 101 is not limited, a hole 101a through which the molten material M which has fallen, passes, is formed in a position which is a lower part. The position of the hole 101a is not limited, but from the point of view of preventing the local residue of the molten material M, the position is preferably the lowest point of the container 101.
    The cavity 102 is configured so that at least the side of the container 101 is open and the molten material M fallen from the container 101 is introduced into the interior of the cavity 102. It is preferable that the refrigerant W is stored at least at a depth to which the cooling acceleration device 103 is submerged. In other words, it is preferable that a liquid level of the refrigerant W is positioned in a position which is higher than an upper end of the cooling acceleration device 103 and close to the upper end.
    Figure 2A is an enlarged perspective view illustrating a configuration of the cooling acceleration device 103 of Figure 1. The cooling acceleration device 103 has a passage forming portion 104 in which a tubular passage s extending in a substantially horizontal direction, and an introduction part 105 through which the molten material M is introduced into the passage forming part 104.
    The passage forming portion 104 is in a state in which at least one end portion 104b, which is a side downstream of the passage, opens and the refrigerant W in the cavity 101 can still enter and exit of the passing training portion 104.
    From the point of view of guiding the molten material M which has fallen into the passage-forming part 104 to flow towards the downstream side (which is close to the end part 104b) along the passage, a end portion 104c, which is a side upstream of the passage forming portion 104, is preferably occupied by a wall. Furthermore, from the same point of view, it is preferable that a lower surface of the passage forming part 104 is inclined to be lower towards the end part 104b.
    The shape of the introductory part 105 is not particularly limited. However, for example, it is possible to provide a through hole formed in a side wall of the passage forming portion 104, in which the molten material M falls from the container 101, facing the container 101 (the upper side of the passage formation part 104, in FIG. 2A). The shape and dimensions of the through hole are determined by taking into account the viscosity of the molten material M.
    It is preferable that a surface of a cross section SI of the passage forming part 104 which is parallel to a lower surface 104a, or 2,000 mm 2 or more and 20,000 mm 2 or less. If the area of the cross section SI is less than 2000 mm 2 , it is difficult to sufficiently cool the molten material M. Also, if the area of the cross section SI exceeds 20 000 mm 2 , a ratio of the part which comes into contact with the refrigerant and is coarsely mixed, and therefore the rapid boiling of water takes place easily. Furthermore, the lower surface 104a of the passage forming part of the present embodiment is one of the inner wall surfaces of the passage forming part 104, which is positioned on the lower side in the vertical direction with respect to to others, in a state in which the passage forming part 104 is installed in the cavity 102.
    Figure 2B is a sectional view when the passage forming portion 104 of Figure 2A is cut along a plane perpendicular to its direction of extension L (a longitudinal direction). Regarding the transverse shape of the passage, a rectangular shape is illustrated here, but the transverse shape is not limited to it and can have another polygonal shape or a circular shape. However, from the point of view of the stable installation on the lower surface 102a of the cavity 102, it is preferable that the part coming into contact with the lower surface 102a of the cavity is flat.
    It is preferable that a cross section S2 of the passage forming part 104, which is perpendicular to an extension direction L, is vertically elongated. Specifically, in the cross section S2, a maximum horizontal length D2 of the cross section preferably represents from 1 to 200 times a maximum vertical length DI of the cross section.
    As described above, the industrial equipment 100 according to the present embodiment is configured so that the molten material M falls in a tubular passage 104 storing the refrigerant W. After the molten material M has fallen , a space surrounded by the side walls of the passage is in a state in which the molten material collects on the bottom surface of the space, and water collects on the top surface of the space. In this case, since the diffusion of the molten material M in the horizontal direction is limited, a contact surface of the molten material M with the refrigerant W is less than in a case in which the same amount of molten material M is not housed in the passage and spreads to spread over the floor surface. Consequently, it is possible to reduce the ratio of a part of the molten material M, which comes into contact with the refrigerant W and coarsely mixes with the latter, compared to the other part of the molten material M housed in the passage, and thus the rapid boiling of the refrigerant W can be suppressed.
    In addition, in industrial equipment 100 according to the present embodiment, since the molten material M is housed in the hollow space in the passage forming part 104, the heat of the molten material M is maintained in the passage forming portion 104, and the temperature of the refrigerant W stored in the same space rises rapidly. Therefore, the interior of the passage forming portion 104 is in a vapor rich state, and the generation of new water vapor, which is a cause of shock wave generation, does not occur easily, and therefore the rapid boiling of the refrigerant W can be further suppressed.
    Second embodiment [0046] Figure 3A is an enlarged perspective view illustrating a configuration of a cooling acceleration device 203 in industrial equipment according to the second embodiment of the present invention. The cooling acceleration device 203 of the present embodiment includes a plurality of passage forming portions 204. The plurality of passage forming portions 204 are arranged side by side in the width direction so that their directions d 'extension L are parallel to each other. Each of the passage forming parts 204 is provided with an introduction part 205, similarly to the cooling acceleration device 103 of the first embodiment. From the point of view of the introduction of the molten material M intended to fall into the passage-forming part 204 without leaking, it is preferable for the adjacent passage-forming parts 204 to be arranged in immediate contact with one another without gaps, and the side walls can be shared. The configurations of the industrial equipment according to the present embodiment different from the cooling acceleration device 203 are the same as those of the industrial equipment 100 according to the first embodiment.
    The configuration of each of the passage formation parts 204 and the introduction part 205 is the same as that of the passage formation part 104 and of the introduction part 105 in the first embodiment, and in the cooling acceleration device 203 of the present embodiment, at least the same effect can be obtained as that of the cooling acceleration device 103 of the first embodiment.
    In addition, since the plurality of passage forming parts 204 are arranged, even when, for example, the position at which the molten material M falls, is not specified, it is possible to introduce the molten material M in any of the passage-forming parts 204 with a high probability compared to a case in which only one passage-forming part 204 is disposed. Therefore, it is possible to prevent a situation in which the fallen molten material M is not introduced into any of the passage forming parts 204 and comes into contact with the refrigerant W outside the device cooling acceleration 203, and it is possible to prevent the occurrence of the rapid boiling of the refrigerant W with contact.
    First modified example [0050] Figure 3B is a perspective view schematically illustrating a configuration of a cooling acceleration device 213 of the industrial equipment according to the first modified example of the second embodiment of the present invention . In this example, a plurality of insertion parts 215 can be provided on a surface on the container side of a passage forming part 214 in the extension direction L of the passage. The plurality of introduction parts 215 can be arranged at regular intervals in the direction of extension L or can be arranged randomly. In this case, it is possible to further increase the probability that the molten material M can be introduced into any of the passage forming portions 214, compared to the case where the introduction portion 215 is provided a to one in the passing training part.
    Third embodiment [0052] Figure 4 is an enlarged sectional view illustrating a configuration of a cooling acceleration device 303 installed in a cavity 302 storing the refrigerant W, in industrial equipment according to a third embodiment of the present invention. The cooling acceleration device 303 of the present embodiment has a structure in which a plurality of passage forming portions 304 are provided in the vertical direction (a height direction) H by stacking a plurality of shaped elements. plate 306 in order from the bottom 302a of the cavity. In FIG. 4, a case in which the passage forming parts 304 are stacked on two stages, is illustrated by way of example, but three or more stages can be stacked. The configurations of the industrial equipment according to the present embodiment different from the cooling acceleration device 303 are the same as those of the industrial equipment 100 according to the first embodiment.
    Figure 5 is an enlarged top view of the configuration of the cooling acceleration device 303. Except for the plate-shaped element 306 positioned in the lowest position (a plate-shaped element in the position closest to the bottom 302a), each plate-shaped element 306 has an insertion part (hereinafter referred to as the through hole) 305 which guides the molten material M to a passage immediately below. There is no limit to the number of through holes 305. The through holes indicated by solid lines are provided in the first plate-shaped member 306 from above, and the through holes indicated by dotted lines are provided after the second plate-shaped member from above.
    When the molten material M flowing over the plate-shaped element 306 reaches the position of the through hole 305, in certain cases, the molten material M jumps onto the opening region of the through hole 305 and collides with the inner wall on the rear side of the through hole 305. In this case, there is a risk that the molten material M which has collided, will jump and flow outside the device. cooling acceleration 303.
    In order to prevent the flow of the molten material M, it is preferable that the through hole 305 has a shape which diffuses in the direction in which the molten material M flows. By way of such a shape, it is possible to adopt, for example, an elliptical shape, a rectangular shape or the like, formed so that the longitudinal direction is substantially parallel to the direction of flow of the molten material M. From the point of view of increasing the length in the longitudinal direction and removing the opening surface to the minimum, the elliptical shape is still preferable.
    As illustrated in Figure 4, the end portions or the intermediate portions of the passage forming portions 304 of the respective stages can be fixed with a plate-shaped member 307 or the like standing upright in the vertical direction. In this case, the resistance of the passage forming part 304 can be improved, and even if the refrigerant W boils quickly, it is possible to protect the passage forming part 304 from an impact caused by rapid boiling.
    From the point of view of the acceleration of the flow of the molten material M intended to be introduced into the passage-forming part 304, the bottoms (a bottom wall) of the plurality of passage-forming parts are preferably inclined so that the downstream side becomes lower. The tilt angle can be constant or can change continuously or intermittently. In FIG. 4, the case in which the angle of inclination of each stage changes intermittently once, is shown by way of example. That is to say that in each stage, a passage formation part 304A with an angle of inclination a is arranged on the downstream side, a passage formation part 304B with an inclination angle β is disposed of the upstream side, and the tilt angle a on the downstream side is less than the tilt angle β on the upstream side.
    In the structure in which the passage forming parts 304 are stacked in the direction of the height H, as in the present embodiment, the molten material M introduced flows to diffuse in the direction of the height (the sense of depth) H in the passage due to the influence of gravity. Thus, cooling can be achieved without increasing the contact surface with the refrigerant W.
    In the case where the cooling acceleration device according to the three embodiments described above is an integral structure, it is difficult to build the cooling acceleration device in a space which is limited by existing structures and the like, but in the case where the cooling acceleration device is a divisible structure, the cooling acceleration device can be assembled to avoid existing structures. For example, in the case where a plurality of pillars are straight in the execution space according to a form of barrier as an existing structure, even if the cooling acceleration device itself, in its completed state, is too large and does not pass between the pillars, small divided elements can pass between the pillars. That is, it is possible to insert a plurality of divided elements between the pillars and transport them to a predetermined position by rotating them or the like, and a predetermined cooling acceleration device can be assembled between the transported elements.
    Fourth embodiment [0061] Figure 6 is an enlarged sectional view illustrating a configuration of part of a cooling acceleration device 403 installed in a cavity storing the refrigerant, in the industrial equipment according to the fourth embodiment of the present invention. In the cooling acceleration device 403 of this embodiment, a plate-shaped member (a ceiling portion) 406 serving as the ceiling of each passage forming portion 404 is provided with a plurality of corrugated projections (sleeves) 408, each of which projects inside the passage forming portion 404 (which is near the floor), formed in a predetermined position of the plate-like member. The configurations of the industrial equipment according to the present embodiment different from the projection 408 are the same as those of the industrial equipment according to the third embodiment.
    The projection 408 can be formed, for example, by attaching a plurality of other plate-shaped elements to the plate-shaped element 406. There are no restrictions on the directions of attachment, but as shown in Figure 6, for example, the plate-like elements can be fixed to be aligned parallel to each other (so that the main surfaces are opposite to each other) or can be fixed to form a cross (with the main surfaces and the opposite side surfaces between them). The projection 408 can be integral with or separated from the plate-shaped element 406. The configurations of the industrial equipment according to this embodiment different from the projection 408 are the same as those of the cooling acceleration device 303 according to the third embodiment.
    The projection 408 functions as a pocket of water vapor generated with the incoming flow of molten metal, and has a structure in which the vapor does not easily escape to the outside. When the refrigerant flows into each passage forming portion 404 for the first time, steam is accumulated between the projections 408. In order to improve the pocket function of the steam, it is preferable that the projection 408A near the introduction part (the through hole) 405 is longer in the projecting direction different from the other projection 408B.
    In such a configuration, the interior of the passage forming part 404 is in a state rich in vapor, the generation of new water vapor, which is a cause of generation of shock wave, n ' does not take place easily, and therefore the rapid boiling of the refrigerant can be suppressed.
    Fifth embodiment [0066] Figure 7 is an enlarged sectional view illustrating a configuration of part of a cooling acceleration device 503 installed in a cavity storing the refrigerant in industrial equipment according to a fifth embodiment of the present invention. In the cooling acceleration device 503 of this embodiment, a plate-like member (a floor part) 506, which is the floor of each passage forming part 504, is provided with a corrugated projection (a sleeve) 509, which protrudes inside the passage forming portion 504 (which is near the floor), formed in a predetermined position of the plate-like member. The number of projections 509 is not limited. In the present embodiment, a plurality of corrugated projections may be provided on the inner side (the floor side) of the plate-like member 506 serving as the ceiling of each passage forming portion 504 as in the fourth embodiment of achievement. The configurations of the industrial equipment according to this embodiment different from the projection 509 are the same as those of the industrial equipment according to the third embodiment.
    The projection 509 can be formed, for example, by fixing another plate-shaped element on the plate-shaped element 506. It is preferable that the fixing is carried out so that the main surface of the element in the form of a plate is substantially perpendicular to the direction of flow of the molten material. The projection 509 can be integral with or separated from the plate-shaped element 506.
    The projection 509 functions as a sacrificial element to separate the flow of the molten material M for a predetermined period. For example, as illustrated in FIG. 7, in the case in which the projection 509 is fixed opposite the region R immediately below the through hole 505 in a direction of movement D of the molten material introduced into the forming part passage 504, it is possible to prevent the steam from leaving by flowing outside through the hole 505.
    Examples of the material of projections 509 include silica, calcium, iron and the like. By adjusting the number and position of the projections 509, since it is possible to limit the amount of refrigerant positioned in each passage forming part 504, large voids can be obtained in a short period of time, the acceleration coarse mixing phenomenon is prevented, and it is possible to suppress the rapid boiling of water.
    The projection 509 melts in the molten material when the projection 509 comes into contact with the molten material and a predetermined time passes. The molten projection 509 reduces the viscosity of the molten material and diffuses between the passage forming portions and thus becomes an effective component in a subsequent long-term cooling process.
    Sixth embodiment [0072] Figure 8 is an enlarged sectional view illustrating a configuration of part of a cooling acceleration device 603 installed in a cavity storing the refrigerant in industrial equipment according to a sixth embodiment of the present invention. In the cooling acceleration device 603 of this embodiment, a cover element 610A (610) is installed on an upper part of a plate-shaped element (hereinafter also referred to as the upper plate) 606A serving as the ceiling section of a passage forming part 604 in the highest position in the vertical direction H, avoiding the position of the through hole 605. The covering element 610A is made of a material having excellent resistance thermal comprising zirconia or the like. The configurations of the industrial equipment according to this embodiment, different from the covering element 610, are the same as those of the industrial equipment according to the third embodiment.
    Since the cover element 610A is installed, the occurrence of ablation (loss) in the upper plate 606A can be prevented when a molten material M at high temperature flows out. In the case of fine diffusion of the molten material in the cavity, a layer of alkaline concrete such as silica and calcium can be installed on the covering element 610A to reduce the viscosity of the molten material.
    In a plate-shaped element (a lower plate) 606B below the upper plate 606, it is preferable that a covering element 610B is also provided in a position overlapping the position of the through hole 605 of the upper plate 606. In this case, it is possible to prevent a situation in which the molten material M falling through the through hole 605 collides with the lower plate and drills a hole there.
    Seventh embodiment FIG. 9 is an enlarged perspective view illustrating a configuration of an upper surface of a cooling acceleration device 703 of industrial equipment according to a seventh embodiment of the present invention. In cooling acceleration device 703, in preparation for a case where the coolant liquid level is higher than the upper plate (the plate-shaped element) 706A, a plate-shaped protruding part (a vertical plate) 711 is installed on the upper plate 706A. A main surface 71 la of the projecting part 711 is substantially parallel to the vertical direction. The protruding part 711 can be integral with or separated from the upper plate 706. The configurations of the industrial equipment according to this embodiment different from the protruding part 711 are the same as those of the industrial equipment according to the third mode. of achievement.
    Since the protruding part 711 is disposed on the upper plate 706A, even when the molten material flows on the upper plate 706A, since the diffusion range of the molten material is narrow, the acceleration of the coarse mixing phenomenon is prevented, and it is possible to suppress the rapid boiling of the water.
    Eighth embodiment [0079] Figure 10 is an enlarged sectional view illustrating a configuration of part of a cooling acceleration device 803 installed in a cavity storing the refrigerant in industrial equipment according to a eighth embodiment of the present invention. In the cooling acceleration device 803 of the present embodiment, a cover member 812 made of a material with a low melting point is installed to be inserted in a part of the hole emerging from the upper plate 806A. The configurations of the industrial equipment according to this embodiment different from the cover element 812, are the same as those of the industrial equipment according to the third embodiment.
    Since the cover element 812 is made of a material which melts when it comes into contact with the molten material, the molten material which tries to pass through the cover element 812 melts the 'cover element 812, and falls from the molten hole (the through hole) on the lower floor and flows down. The cover element 812 which remains without melting, plays a role of blocking the exit of the steam in the cooling acceleration device 803, and it is possible to increase the temperature of the refrigerant.
    While the preferred embodiments of the invention have been described and illustrated above, it should be understood that they are exemplary of the invention and are not considered to be limiting. Additions, omissions, substitutions and other modifications may be made without departing from the spirit or scope of the present invention. Consequently, the invention should not be considered as limiting by the preceding description, and is only limited by the scope of the appended claims.
