    description
    Casting device with holder of a shadow tube on the pan closure
    The present invention relates to a pouring device for pouring a liquid metal from a pouring vessel, wherein the pouring device has a ladle closure arranged on the underside of the pouring vessel for regulating the outflow of liquid metal from the pouring vessel, the ladle closure having an outlet opening on its underside, through which the liquid metal emerges from the pouring vessel when the pan is open.
    Such a casting device is well known.
    In order to cast liquid metal - for example liquid steel - in a continuous casting plant, so-called shadow tubes are almost always used in the prior art. By means of the shadow tubes, the liquid metal is protected during encapsulation of the casting vessel - usually a ladle - in the distributor (tundish) or other vessel from environmental influences, so that the chemical composition of the liquid metal does not change during encapsulation. In the prior art, the shadow tube is pressed by means of manual, electrical or hydraulic manipulators permanently to the underside of the pan closure. This results in a connection between the movable ladle and the stationary part of the caster during casting.
    In the normal casting of the casting plant, the connection is not critical, since it can be solved again at any time. However, it is possible that the shade tube glued to the casting vessel. In case of sticking an immediate release of the shadow tube from the casting vessel is not possible. If such a sticking occurs in the regular casting operation, this leads to a casting break, since the pouring vessel from the place where it is located, can not be moved away. It is even more critical if, in an emergency situation, a movement of the casting vessel is required. If sticking occurs in such an emergency situation, the manipulator impedes the movement away from the casting vessel. In extreme cases, this can lead to the liquid metal flowing onto the casting platform of the casting plant and destroying it.
    In the prior art, these risks have been accepted so far, since no solutions were known to avoid the problem.
    The object of the present invention is to develop a casting device of the type mentioned in such a way that the above-mentioned problems are solved in a simple and cost-effective manner.
    The object is achieved by a casting device with the features of claim 1. Advantageous embodiments of the pouring device according to the invention are the subject of the dependent claims 2 to 11.
    According to the invention, a pouring device of the type mentioned at the outset is configured in that the cup closure has a holding device on its underside in the region of the outlet opening, that a shadow tube attached from below to the underside of the ladle closure is held by the holding device via a counter holding device, that the Counter-holding device is arranged at an upper end of the shadow tube and - that the counter-holding means, based on a vertical, surrounded by the outlet opening axis, laterally has a recess through which the shadow tube before attaching the shadow tube to the underside of the pan closure laterally into the counter-holding device is insertable.
    By the inventive design of the pouring is achieved on the one hand that a manipulator - for example, an industrial robot - only for attaching the shadow tube to the pan closure and for later removal of the shadow tube from the pan closure is in the path of movement of the casting vessel. Even if there should be sticking of the shadow tube on the ladle closure in the casting operation, this is therefore not critical, since the shadow tube is not held by the manipulator, but is attached directly to the pan closure. A movement of the casting vessel is therefore possible in this case. On the other hand is achieved by this configuration that the counter-holding device can be connected directly to the shadow tube when changing the shadow tube. The counter holding device therefore does not have to be present multiple times and in each case be connected in advance to one of the shadow tubes, but only has to be present once.
    The shadow tube must be able to withstand contact with the liquid metal. It therefore consists - as in the prior art - of a refractory material. Such materials are usually brittle. The holding device and the counter holding device, however, do not come into contact with the liquid metal. They can therefore consist of a different material. In most cases, the holding device and the counter-holding device made of metal. As a metal, in particular steel comes into question.
    It is possible in individual cases that, viewed in the direction of the vertical axis, the lateral recess is present only in a lower region of the counter-holding device, ie the counter-holding device is annularly closed in an upper region facing the ladle closure. Preferably, however, the lateral recess is designed to be continuous in the direction of the vertical axis, so that the counter-holding device has a C-shaped cross section in a plane orthogonal to the vertical axis. Thus, there is preferably no position in the direction of the vertical axis, in which the counter-holding device has an annularly closed cross-section.
    In many cases, as viewed in the direction of the vertical axis, the shadow tube has a central region in which the shadow tube, viewed in the plane orthogonal to the vertical axis, has a minimum diameter. Furthermore, the shadow tube usually widens in the direction of the vertical axis towards the underside of the pan closure. The expansion can in particular be conical. Preferably, the lateral recess is dimensioned such that the shadow tube can be introduced laterally into the counter-holding device only when the counter-holding device is located in the central region of the shadow tube, as viewed in the direction of the vertical axis. The counter-holding device is thus initially guided for receiving the shadow tube in the central region of the shadow tube laterally over the shadow tube, so that the counter-holding device engages around the shadow tube like a fork. Then, the counter-holding device in the direction of the upper, in the attached state adjacent to the socket closure end of the shadow tube is guided until the counter-holding device engages the shade tube.
    The shadow tube preferably has a collar on its outer end facing the ladle closure on the outside. Correspondingly, the counter-holding device, based on the vertical axis, on a radially inwardly projecting C-shaped web on on which rests on the collar of the shadow tube after the lateral insertion into the counter-holding device.
    Preferably, the pouring device is designed such that the holding device has a number of L-shaped receptacles, that the receptacles are distributed around the outlet opening, relative to the vertical axis, that the holding device has a corresponding number of holding elements, - That for connecting the shadow tube with the pan closure, the counter-holding device is guided in the direction of the vertical axis to the holding device, so that the
    Holding elements of the holding means are introduced into the receptacles of the counter-holding device, and then the counter-holding means is rotated about a predetermined angle of rotation about the vertical axis.
    The connection of the shadow tube with the pan closure can thus be designed in the manner of a bayonet closure. This type of connection is particularly easy to implement and works very reliable.
    The number of shots and the corresponding number of holding elements can be determined as needed. Preferably, the number of L-shaped receptacles is exactly two and the L-shaped receptacles, relative to the vertical axis, arranged offset by 180 ° from each other.
    The recordings have guide slots on which abut the holding elements of the holding device during rotation about the angle of rotation. Preferably, the guide slots run out horizontally or with a negative slope. As a result, unintentional loosening of the connection of the shadow tube and pan closure, for example, due to vibration or vibration occurring during operation is not possible.
    In a further preferred embodiment of the pouring device is provided - that the counter-holding device has a holding part in which the shadow tube is held in the counter holding device after the lateral insertion, wherein the holding part is stationary after the lateral insertion of the shadow tube in the counter holding device relative to the shadow tube, - That the counter-holding device has a fastening part, with which the counter-holding device is connectable to the holding device of the ladle closure, so that the fastening part is stationary after connection to the holding device relative to the holding device, - that the holding part is movable relative to the fastening part in the direction of the vertical axis and in the direction of the vertical
    Axle is acted upon by a spring force, so that during the connection of the fastening part with the holding device, the holding part relative to the fastening part by a force exceeding the spring force in the direction of the vertical axis is deflected downwards.
    As a result, on the one hand a stable, tight closure between the shade tube and pan closure can be achieved. Nevertheless, due to the deflectability there is no risk of damage to the - brittle and therefore brittle - shadow tube.
    The counter-holding device preferably has an engagement device for attaching an assembly tool to the counter-holding device. Thereby, the counter-holding device can be easily connected by means of a manipulator with the holding device and released from it.
    The ladle closure preferably has, in the region of the outlet opening, an attachment tip serving to guide the liquid metal, which protrudes into the upper end of the shadow tube. This achieves or improves a stable, tight seal between the shadow tube and the pan closure.
    As a rule, the shadow tube has a widening on its upper end facing the ladle closure. Preferably, the attachment tip protrudes into the expansion. As a result, the stable, tight seal between the shade tube and pan closure can be further improved.
    The above-described characteristics, features and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following description of the embodiments, which will be described in more detail in conjunction with the drawings. 1 shows a ladle with a pouring device and a

    According to FIG. 1, liquid metal 1 - for example liquid steel 1 - is to be poured from a casting vessel 2 into another vessel 3, for example a tundish. To regulate the outflow of liquid metal 1 from the casting vessel 2, a casting device has a ladle closure 4. The ladle closure 4 is arranged on the underside 5 of the pouring vessel 2.
    The ladle closure 4 has, according to FIG. 2, an outlet opening 7 on its underside 6. Through the outlet opening 7, the liquid metal 1 emerges from the pouring vessel 2 when the pan closure 4 is open. For opening and closing the outlet opening 7, the ladle closure 4 has a closure device (not shown in the FIGURE). The Verschlussein direction may in particular, as indicated in Figure 1 by a double arrow A, be designed as a slide.
    The ladle closure 4 furthermore has a holding device 8 on its underside 6. The holding device 8 is arranged in the region of the outlet opening 7. The holding device 8 is usually made of steel.
    Of the holding device 8, a shadow tube 11 is held via a counter-holding device 10, which is attached from below to the bottom 6 of the pan closure 4. The counter-holding device 10 is arranged at an upper end of the shadow tube 11. It usually consists of steel. The shadow tube 11, however, consists of a refractory material.
    An embodiment of the holding device 8 and the counter-holding device 10, which as such is not the subject of the present invention, will be explained below in conjunction with FIGS. 2 to 6. However, the present invention is based essentially on this embodiment. Also, the knowledge of the explained in connection with the Figures 2 to 6 embodiment facilitates the understanding of the present invention.
    In order to ensure a stable connection of the holding device 8 and the counter-holding device 10 with one another, the holding device according to FIGS. 2 to 6 can have a number of receptacles 12. The receptacles 12 can - see particularly clearly FIG. 6 - be designed in particular L-shaped. The receptacles 12 can, with respect to the vertical axis 9, distributed uniformly around the outlet opening 7 around. The counter-holding device 10 has a corresponding number of holding elements 13. In each receptacle 12 so in the connected state of the holding device 8 and counter-holding device 10 each have a holding element 13 is inserted. The holding elements 13 may be formed, for example, as round bolts which project radially away from the vertical axis 9.
    The L-shaped receptacles 12 are open at the bottom. For connecting the shadow tube 11 to the ladle closure 4, the counter holding device 10 (and with it the shadow tube 11) is guided upward, for example by means of the manipulator 14 shown in FIGS. 3 and 4, ie in the direction of the vertical axis 9 on the ladle closure 4 to move. This movement takes place until the holding elements 13 are inserted into the receptacles 12 - more precisely: in corner regions of the receptacles 12. Then, the counter-holding device 10 is rotated according to FIG. 3 by a predetermined angle of rotation α about the vertical axis 9, thereby producing the connection between the holding device 8 and the counter-holding device 10.
    The receptacles 12 have according to FIG 6 guide slots 15. During the rotation of the counter-holding device 10 by the angle of rotation α, the holding elements 13 of the counter-holding device 10 are in contact with the guide slots 15. The guide slots 15 have in initial areas 16 a positive slope. In end regions 17, however, they run horizontally (shown in broken lines in FIG. 6) or, as shown in FIG. 6 by solid lines, with (slightly) negative slope.
    The shadow tube 11 is preferably not manually, but fixed by means of the manipulator 14 on the underside 6 of the pan closure 4 and released from the bottom 6 of the pan closure 4. The manipulator 14 may be formed, for example, as an industrial robot. Regardless of its concrete design, however, the manipulator 14 according to FIGS. 3 and 4 has an assembly tool 18. For stable interaction of the assembly tool 18 with the counter-holding device 10, the counter-holding device 10 has an engagement device 19, to which the assembly tool 18 can be attached. The engagement device 19 may be formed, for example, as an arrangement of two surfaces which are either parallel and have a guide aid in an initial region or are slightly conical at a small angle. The angle can for example be between 2 ° and 10 °.
    The ladle closure 4, according to FIG. 2, usually has an attachment tip 21 in the region of the outlet opening 7. The attachment tip 21 serves to guide the liquid metal 1 out of the casting vessel 2 into the shadow tube 11. In a preferred embodiment, the attachment tip 21 protrudes into the upper end of the shadow tube 11. Usually, the shadow tube 11 has a widening 22 at its upper end facing the socket closure 4. The attachment tip 21 preferably protrudes into the widening 22 as shown in FIG.
    The shadow tube 11 is, as already mentioned, made of refractory material. It is therefore relatively brittle and breaks easily. The shadow tube 11 should therefore be kept as free as possible of mechanical stresses in the counter-holding device 10. For this purpose, the shadow tube 11 may have, for example, a collar 23 at its upper end facing the ladle closure 4, for example. The counter-holding device 10 has in this case on a webs on 24. The on-web 24 protrudes radially inward and overlaps the collar 23rd As a result, the shadow tube 11 can be held in the counter holding device 10 stable, reliable and stress-free. In particular, after inserting the shadow tube 11 into the counter-holding device 10, the collar 23 can rest on the support web 24.
    Based on the above explanations to FIGS 2 to 6 are now in conjunction with the 7 to 10, the essential differences and then advantageous embodiments of the present invention to the above embodiment of the retainer 10 and - if necessary - the holding device 8 - explained.
    The decisive difference is that in the embodiment according to FIGS 2 to 6, the counter-holding device 10, based on the vertical axis 9, is annularly closed, while in the embodiment according to the invention shown in FIGS 7 to 10, the counter-holding device 10, based on the vertical , 9 surrounded by the outlet opening axis 9, one side
    Recess 25 has. The recess 25 is configured such that the shadow tube 11 can be inserted laterally into the counter-holding device 10 through the recess 25. The insertion of the shadow tube 11 into the counter-holding device 10 takes place, of course, before the attachment of the shadow tube 11 to the underside 6 of the ladle closure 4. The recess 25 may be designed to be continuous in particular in the direction of the vertical axis 9, as shown in FIGS. 7 to 9. The counter-holding device 10 thus has a C-shaped cross section in a plane orthogonal to the vertical axis 9.
    Incidentally, the counter holding device 10 can also be configured as has been explained above in connection with FIGS. 2 to 6, but not necessarily. Due to the lateral recess 25 but also the support web 24, on which rests the collar 23 of the shadow tube, C-shaped. This can be seen particularly clearly from FIGS. 7 and 8.
    Preferably, various advantageous embodiments of the casting device are realized, by means of which deviates from the embodiments of Figures 2 to 6. These embodiments - which, however, as already mentioned, are not mandatory, - are explained below.
    A preferred embodiment is that viewed in the direction of the vertical axis 9, the shadow tube 11 has a central region 26. The central region 26 is that region in which the shadow tube 11, viewed in the plane orthogonal to the vertical axis 9, has a minimum diameter. As can be seen in particular from FIGS. 7 and 8, the shadow tube 11, seen in the direction of the vertical axis 9, can expand toward the underside 6 of the ladle closure 4. The expansion can be step-like. Preferably, the expansion is conical, as shown in FIGS. 7 and 8. The lateral recess 25 is preferably dimensioned in such a way that the shadow tube 11 can only be inserted laterally into the counter holding device 10 if the counter holding device 10 is viewed in the direction of the vertical axis 9 as viewed in FIGS. 7 and 8 middle region 26 of the shadow tube 11 is located. In all other axial positions insertion of the shadow tube 11 in the counter-holding device 10 is not possible in this case. Alternatively, the shadow tube 11 (except for the upper portion in which the collar 23 is located) may have a uniform cross section. In this case, the shadow tube 11 can of course also be introduced into the counter holding device 10 at other axial positions.
    Another difference, according to the representation in Figures 7 to 10 is that the L-shaped receptacles 12 are indeed present, but not part of the holding device 8, but part of the retainer 10 are. The holding elements 13 are in this case part of the holding device 8. It is thus realized in comparison to the 2 to 6, the kinematically inverse procedure.
    As before, the receptacles 12, with respect to the vertical axis 9, are arranged distributed around the outlet opening 7. Also, the number of retaining elements 13 still corresponds to the number of L-shaped receptacles 12. Also, the type of connection is as before in the manner of a bayonet lock. For connecting the shadow tube 11 with the pan closure 4 so the counter-holding device 10 is guided in the direction of the vertical axis 9 to the holding device 8, so that the holding elements 13 (this time the holding device 8) in the receptacles 12 (this time the retainer 10) are introduced , Then, as before, the rotation of the counter-holding device 10 by the rotation angle α about the vertical axis. 9 Thus, in particular, the rest of the configuration of the receptacles 12 is explained above in connection with FIGS. 2 to 6. The receptacles 12 thus have the guide slots 15. The design of the guide slots 15 is already explained above. The holding elements 13 of the holding device 8 are thus during the rotation about the rotation angle α to the guide slots 15. The guide slots 15 also run horizontally or with a negative gradient.
    In the embodiment according to FIGS. 2 to 6, the number of L-shaped receptacles 12 is four. In contrast, the number of L-shaped receptacles 12 in the embodiment of FIG 7 to 10 exactly two. The two L-shaped receptacles 12 are, relative to the vertical axis 9, offset by 180 ° from each other. So they are diametrically opposed to each other.
    Another essential embodiment of the counter-holding device 10 according to the invention consists in that the countershark device 10 has a holding part 27 and a fastening part 28, wherein the holding part 27 is movable relative to the fastening part 28 in the direction of the vertical axis 9.
    The holding part 27 is that part of the counter-holding device 10 in which the shadow tube 11 is held in the counter-holding device 10 after the lateral insertion. After the lateral insertion of the shadow tube 11 in the counter-holding device 10, the holding part 27 is fixed relative to the shadow tube 11. The holding member 27 includes, for example, the support bar 24, if it is present.
    The fastening part 28 is that part of the counter-holding device 10 with which the counter-holding device 10 can be connected to the holding device 8 of the pan closure 4. The fastening part 28 includes, for example, the L-shaped receptacles 12, if they are present. The fastening part 28 is stationary after connection to the holding device 8 relative to the holding device 8.
    The holding part 27 is, as already mentioned, movable relative to the fastening part 28 in the direction of the vertical axis 9. It is acted upon in the direction of the vertical axis 9 with a spring force. The spring force acts upwards, ie towards the underside 6 of the socket closure 4. When a downwardly acting force is exerted on the holding part 27, which the
    Spring force exceeds, while at the same time the fastening part 28 is held in a fixed position, the holding part 27 is relative to the fastening part 28 in the direction of the vertical axis 9 deflected downward. This state occurs in particular during the connection of the fastening part 28 with the holding device 8.
    To realize the spring force, for example, a number of bolts 29 may be present, which are screwed from below into the fastening part 28, so that screw heads of the threaded bolts 29 have a predetermined distance a from the fastening part 28. This is illustrated for a single one of the bolts 29 in FIG. Bolt necks of the bolt 29 penetrate recesses 30 of the holding part 27. The recesses 30 have a slightly larger diameter than the screw necks of the bolt 29. For example, springs 31 can be arranged between the recesses 30 and the screw heads of the threaded bolts 2 9. The springs 31 exert on the holding part 27, the upward spring force by means of which the holding member 27 is pressed to the bottom 6 of the pan closure 4.
    In FIGS. 7 to 9, two screw bolts 29 are shown per receptacle 12, ie a total of four bolts 29. However, the number of bolts 29 can also be larger or smaller.
    In summary, the present invention relates to the following facts:
    A pouring device for pouring a liquid metal 1 from a pouring vessel 2 has a ladle closure 4 for regulating the outflow of liquid metal 1 from the pouring vessel 2. The ladle closure 4 is arranged on the underside 5 of the pouring vessel 2. It has on its underside 6 an outlet opening 7, through which the liquid metal 1 emerges from the pouring vessel 2 when the pan closure 4 is open. The ladle closure 4 has on its underside 6 in the region of
    Outlet opening 7, a holding device 8. From the holding device 8, a shadow tube 11 is held via a counter-holding device 10, which is attached from below to the underside 6 of the ladle closure 4. The counter-holding device 10 is arranged at an upper end of the shadow tube 11. The counter-holding device 10 has, based on a vertical, surrounded by the outlet opening 7 axis 9, laterally a recess 25. Through the lateral recess 25 through the shadow tube 11 is inserted laterally into the counter-holding device 10 before attaching the shadow tube 11 to the bottom 6 of the pan closure 4.
    The present invention has many advantages. In particular, the problems of the prior art, which may occur in the case of gluing the shadow tube 11 on the pan closure 4, can be completely avoided. For the manipulator 14 is only required for attaching the shadow tube 11 on the pan closure 4 and for later removal of the shadow tube 11 from the pan closure 4. A holding of the shadow tube 11 during the casting operation itself, however, is not required. Even in cases of malfunction and emergency, the ladle 2 can therefore be moved away from the casting position immediately and at any time. Furthermore, due to the lateral recess 25 only a single counter-holding device 10 is required.
    Although the invention has been further illustrated and described in detail by the preferred embodiment, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
