Dart feeding device for in-dart dart feeding device
[16] The present invention relates to a dart feeder for use in a dart injector that prevents the outflow of slag by closing the tap at the time when the tapping is completed during the converter tapping operation, and in particular, automatically mounts or mounts the dart to the dart input device. It relates to a dart supply device for.
[17] The converter process is a method of using a converter as a steelmaking furnace as a method of making steel from pig iron.
[18] It is divided into acidic converter method and basic converter method, and it rotates jar-shaped furnace body and drains water. This converter method injects molten pig iron into the converter and blows it with high pressure air to oxidize and remove impurities in the raw material to make steelmaking. When melting pig iron in the converter, slag of solvents, nonmetallic substances, and metal oxides Is produced in large quantities and floats or remains on the water, and the molten metal produced in the converter is pulled out by opening or tilting the tap.
[19] When tapping is almost completed from the converter, the height of the injection ladle and the state of the tapping flow are judged to finish the tapping, and at the same time, the converter is established to prevent further flow of the slag, but when establishing the converter, a large amount of molten steel in the ladle is established. Due to the impurities contained in the slag, this results in poor steelmaking, segregation and lower error rate, leaving 20 ~ 30% of the molten metal in the converter without leaving it.
[20] In this way, the method of tilting the converter appears as a problem that the slag does not come out of molten metal or the molten metal is not sufficiently pulled out depending on the position of the converter in the tapping stage despite the steelmaking efficiency of the converter method. It is known how to put the slag checkball inside.
[21] In this method, a steel sphere with a specific gravity of about 7 is made, and a caster ball, a refractory with a specific gravity of about 7, is spherically bonded to the sphere, and fired. The volume ratio of the steel sphere and the caster ball is about 4: 6, which is molten steel. It is a way to block the entrance by putting it in.
[22] In other words, if the converter is tilted toward the tap after finishing the blow, the slag with small specific gravity floats on the upper part of the molten steel, and the heavy molten steel is pulled out with the ladle through the tap and the slag check ball is thrown at the end of tapping. By floating between the upper slag and the lower molten steel layer, the molten steel in the converter is significantly reduced and the slag check ball blocks the exit.
[23] The use of this method can increase the amount of molten steel and further reduce the slag flow rate by blocking the exit according to the steel tapping in the converter without directly tilting the converter.
[24] Another method is known to inject dart into the converter. As shown in Fig. 1, the dart 16 has a long pin portion and a conical ball treated with refractory, so that the ball descends due to the specific gravity difference while the pin enters the tap hole of the tap, thereby blocking the tap 17. The role of the darts alone is more robust than slag checkballs.
[25] The apparatus for injecting the dart into the converter is described in detail in US Patent Nos. 4,553,743, 4,634,106, 4,640,498, and Korean Patent Nos. 287127 and 287128, which are registered by the present applicant, and the techniques are described in Dart 16.

It is made of a guide frame 15, it is a dart input device that is appropriately provided with a driving unit for moving the lance 14 along the guide frame 15 and its drive unit. Reference numeral 18 is a 'lance head' provided in the lance for mounting the dart 16 to the lance 14.
[26] For reference, the technology of Korean Patent Registration No. 287127 is provided with a hoist on a fixed frame to connect the chain to a guide frame, and the fixed frame has a hanger beam extending away from the tilting unit at an arbitrary distance, toward the end thereof. A support bracket is installed, and the guide frame is provided with a lance supporter roller at the end, and a tilting bracket is installed on one side of the guide frame, and the support bracket of the hanger beam is coupled to the rotating shaft. Provides durability, stability, operability and more.
[27] However, this technique is a device for introducing the dart into the converter, and a specific method of mounting the dart in the lance is not considered. In other words, the dart is mounted on the lance or mounted on the manpower, so that it is difficult to install as much as there was a problem of working constraints depending on the ambient temperature.
[28] Accordingly, an object of the present invention is to provide a dart supply apparatus capable of mounting or mounting a dart in place of a dart input device installed in the vicinity of a converter.
[29] Another object of the present invention is to enable timely supply of the dart required in the dart input device regardless of the ambient temperature atmosphere.

Moving plate 24 mounted to move in the direction, the lifting table 25 is mounted to the moving plate 21 and provided with a drive unit to enable the vertical movement between running or stop, and the dart mounted on one end of the lifting table 25 The dart clamper 26 which clamps 16 and the dart loading stand 27 which locates in the moving area of the dart clamper 26, and accumulates several darts 16 are provided.
[40] The frame 22 is supported by the frame supporter 21 so as to guide the horizontal movement while supporting the moving plate 24 to rise to a predetermined height from the ground. The moving plate 24 is mounted to the frame 22 to move horizontally along the frame 22 in accordance with the rotational direction of the driving motor 23, and supports the platform 25 in a state capable of vertically moving at one end thereof. .
[41] The lifting platform 25 is supported by a bracket 28 on the moving plate 24 and includes a driving unit. The drive unit is mounted in the vertical direction to the bracket 28, the screw 29 to move up and down in the vertical axis direction under the rotational force, and the screw 29 is mounted to the screw 29 to rotate the screw 29 up and down The lifting motor 30 is made up.
[42] In addition, the dart clamper 26 is attached to one end of the platform 25. The dart clamper 26 has several dart fingers 31 whose tip can hold the dart 14. The dart clamper 26 fixing the dart finger 31 is coupled to the platform 25 by the track 32 to enable the transverse transportation along the platform 25, and is driven by the traverse motor 33. Along 32 is transported in a given area.
[43] In addition, the dart holder 27 is a disc-shaped loading plate 34 capable of placing darts so that at least one or more darts 16 can be stacked at the same time, and a rotation capable of rotating the loading plate 34. The support base 36 which supports the motor 35 and the base plate 34 so that it may be located in arbitrary height from the ground is provided.
[44] The dart supply device according to the present invention is thus provided with a frame 22, a moving plate 24, a platform 25 and a dart clamper 26 having a dart finger 31, and a dart holder 27. As an example, the peripheral device of the dart supply device for mounting or mounting the dart 16 on the side of the dart input device has characteristics.
[45] Here, the dart finger 31 may be applied as a robot arm, and the dart holder 27 is not necessarily required. That is, as in the embodiment, a plurality of darts 16 may be continuously mounted on a magazine (base plate) and the magazine may be rotated, and another structure may be continuously supplied to another structure that can be inserted one by one from the upper side. have.
[46] Looking at the effect of the dart supply device according to the present invention in relation to the dart input device as follows.
[47] The dart injector generally has a long lance 14 for direct dart into the converter, the end of the lance 14 being a suitable lance head 18 for holding the dart 16. , The dart supply device 20 of the present invention is designed to transport and mount the dart 16 to the lance 14 or a similar dart inlet on the side of the dart injector.
[48] Figure 2 schematically shows the entire process of mounting the dart 16 in accordance with the operation of the dart supply device 20 according to the present invention with respect to the lance 14 on the side of the dart input device located in the periphery of the converter 10. One dart 16 is moved in the direction of the lance 14 by clamping one dart 16 through the dart clamper 26 to move the one dart 16 to the head 18 of the lance 14. It shows the whole process of mounting on.
[49] For reference, the support structure of the frame 22 shown in FIG. 2 is a case in which the upper support type structure is applied, and in the case of the upper support type frame 22, the height of the frame can be artificially adjusted. In addition, the height of the frame can be adjusted to obtain a gain to facilitate alignment and placement of the dart supply device according to the position of the dart input device, but the structure is complicated.
[50] Figure 3 is a side view showing the main part of the dart supply apparatus according to the present invention, the moving plate 24 mounted to the frame 22 is the length of the frame 22 (horizontal) when the traveling motor 23 is rotated Move along the direction. Movement of the moving plate 24 determines the current position of the dart clamper 26. That is, the horizontal position of the platform 25 and the dart clamper 26 as a whole is determined by the moving plate 24, which is a positioning motion of the dart clamper for clamping and transporting the dart.
[51] On the contrary, the vertical direction movement is a movement of determining the vertical position of the dart clamper 25 by vertically moving the platform 25, and appears during the clamping / unclamping time of the dart, and the screw 29 is rotated by the lifting motor 30. 1) rotates the platform 25 by the amount of rotation thereof to determine the position of the dart clamper 26.
[52] Another vertical movement occurs when only the dart clamper 26 is moved independently with the moving plate 24 and the platform 25 having the positions on the x and y axes of the dart clamper 26 determined. Holding and clamping state of the dart 16 via the dart finger 31, i.e. removing the dart 16 from the loading stand 27 or mounting or mounting the dart 16 to the lance 14 of the dart input device. When the transverse motor 33 rotates as the horizontal movement of the dart clamper 26 for the dart clamper 26 moves along the track on the platform 25.
[53] 4 (a) to (i) are flow charts of the clamping / unclamping step of the dart by the dart supply device according to the present invention.
[54] (a) is a home position with the moving plate 24 moving to the dart loading base 27 and setting the initial position of the dart clamper 26. FIG.
[55] (b) drives the transverse motor 33 of the dart clamper 26 mounted on the platform 25 so that one dart 16 is placed on the dart holder 27 via the dart finger 31. It is the hold process of the dart caught.
[56] (c) is the case where the dart clamping is performed by restoring the position of the dart clamper 26 driven in (b) to completely remove the dart 16 from the dart holder 27. When this state is finished, the dart magazine of the loading base 27, ie, the loading plate 34 is rotated by the predetermined sector to position the next dart in the fingering standby state. However, the positioning of the dart magazine does not have to be executed at this time.
[57] (d) drives the moving plate 24 again to carry the dart clamped to the dart clamper 26 to carry the dart to the position where the lance 14 of the dart input device is located, ie near the dart head 18 in the lance. It is a transport process.
[58] (e) is a dart positioning process for mounting the dart clamped on the dart clamper 26 on the lance head 18 by precisely adjusting the height of the platform 25 about the lance head 18.
[59] (f) is a centering process in which the dart is moved to the center of the lance head 18 by moving the dart clamper 26.
[60] (g) raises the platform 25 again when centering is completed, accurately pushes the dart 16 into the lance head 18, and simultaneously operates the dart finger 31 on the dart clamper 26 to maintain the dart's holding state. This is an unclamping process.
[61] (h) is an escape process in which the dart clamper 26 returns from the dart 16 in accordance with the direct downward motion of the dart clamper 26 by the lifting platform 25 or a chain motion by the transverse motor 33.
[62] (i) is a stand-by state for performing the above steps (a) to (h) and returning to position (a) again to clamp the next target dart 16.
[63] Thus, if the dart is supplied to a predetermined dart input device by performing the whole process of (a) to (i), the dart can be supplied as well as accurate even under poor working conditions.
[64] Here, the dart clamper 26 may be replaced by a robot arm unit or the like. In addition, as an example of the present invention, the application of the rotary dart loading rack is described, but the application of the vertical downward dart feeding method is also possible. In addition, the application of the upper support frame and the fixed frame may be appropriately selected depending on the installation conditions of the dart input device. In addition, when the interlock is provided through proper control of the motor and the driving unit in accordance with the operation cycle of the dart input device, unmanned operation is also possible.
[65] As described above, since the present invention can accurately and mechanically supply one dart into the dart input device for injecting the dart into the converter, it is possible to improve the operation efficiency of the converter by improving various problems caused by the supply of dart-dependent darts. have.
[66] In addition, since the dart can be supplied quickly, easily, accurately and stably to the dart input device, the operation reliability is maintained and the dart input device is linked to the dart input device, thereby achieving the efficiency of operating the dart input device.
