Description

Technical Field

[0001] The utility model relates to the field of steel metallurgy continuous casting equipment, in particular to a crystallizer plugging and ingot drawing device. Background Art

[0002] The crystallizer is a continuous steel casting equipment that receives the molten steel injected from the intermediate tank and solidifies it into a solid billet shell according to the specified cross-sectional shape. It is the most critical component of the continuous casting machine, and its structural material and performance parameters play a decisive role in the quality of the billet and the production capacity of the casting machine.

[0003] In existing steel smelting, continuous casting machine tubular crystallizers are mostly used. The continuous casting machine tubular crystallizers include two types of equipment: square billet crystallizers and round billet crystallizers, which are convenient for producing square billets and round billets. The inner walls of the square billet crystallizer and the round crystallizer are both provided with copper tubes for cooling or heating. When preparing for ingot production, the ingot head needs to be placed in the discharge port of the crystallizer, and the asbestos rope used for heat insulation and sealing is inserted into the gap between the ingot head and the copper tube on the inner wall of the crystallizer, so as to ensure subsequent production.

[0004] In the prior art, the staff manually inserts the asbestos rope into the gap between the ingot starter and the copper tube on the inner wall of the crystallizer. The tool used is often a slender rod-shaped steel chisel. When operating the steel chisel, the user first inserts one end of the asbestos rope into the gap through the steel chisel, and then continues to operate the steel chisel to insert subsequent asbestos ropes into the gap until the asbestos rope isolates the ingot starter and the copper tube. The disadvantage is that the overall operation time is relatively long, and during the plugging operation, the copper tube on the inner wall of the crystallizer is easily damaged due to the hard structure and material of the steel chisel. The damaged copper tube not only shortens the service life of the copper tube, but also scratches the ingot and affects the quality. Utility Model Content

[0036] To further understand the purpose, structure, features, and functions of the present utility model, the following is a detailed description in conjunction with embodiments.

[0037] As shown in Figure 1-9As shown in the figure, a mold plugging dummy bar device according to an embodiment of the present utility model includes a first plugging member 1000 for operating the gap of a square mold, a second plugging member 2000 for operating the gap of a circular mold, a grip bar 3000, a pushing assembly 4000, and a pin 8000. The pushing assembly 4000 includes a first pushing portion, a second pushing portion, and a transmission member;

[0038] One end of the first plugging member 1000 is provided with a first placement groove 1100, and the other end of the first plugging member 1000 is provided with a first insertion end 1400. One end of the second plugging member 2000 is provided with a second placement groove 2100, and the other end of the second plugging member 2000 is provided with a second insertion end 2400. One end of the grip bar 3000 is provided with a third insertion end 3300, and the other end of the grip bar 3000 is provided with a fourth insertion end 3400. The third insertion end 3300 is inserted into the first insertion end 1400, and the fourth insertion end 3400 is inserted into the second insertion end 2400. Moreover, a pin hole 7000 is provided in each of the first insertion end 1400, the second insertion end 2400, the third insertion end 3300, and the fourth insertion end 3400. The pin 8000 passes through the pin holes 7000 of the first insertion end 1400 and the third insertion end 3300 to fix the first plugging member 1000, and the pin 8000 passes through the pin holes 7000 of the second insertion end 2400 and the fourth insertion end 3400 to fix the second plugging member 2000;

[0039] The first pushing portion is arranged inside the first plugging member 1000, the second pushing portion is arranged inside the second plugging member 2000. One end of the first pushing portion cooperates with the first placement groove 1100, and one end of the second pushing portion cooperates with the second placement groove 2100. The transmission member is arranged inside the grip bar 3000, and the transmission member drives the other ends of the first pushing portion and the second pushing portion respectively;

[0040] Among them, when the user needs to use a crystallizer plugging dummy bar device of the present utility model to plug the gap between the inner wall of the square crystallizer copper tube and the dummy bar head, the user first assembles the first plugging member 1000, the second plugging member 2000, the holding rod 3000 and the pushing assembly 4000. After the assembly is completed, the asbestos rope 6000 with the appropriate length is placed into the first placement groove 1100 of the first plugging member 1000. Then, the first plugging member 1000 is inserted into the gap between the inner wall of the square crystallizer copper tube and the dummy bar head by holding the holding rod 3000. After inserting a certain distance, the user operates the pushing assembly 4000 to push the first pushing part, so that one end of the first pushing part pushes the asbestos rope 6000 in the first placement groove 1100 until the asbestos rope 6000 breaks away from the first placement groove 1100. At this time, the first pushing part reaches the maximum pushing limit. If it is necessary to use a crystallizer plugging dummy bar device of the present utility model to plug the gap between the inner wall of the circular crystallizer copper tube and the dummy bar head, the asbestos rope 6000 with the required appropriate length needs to be placed into the second placement groove 2100 of the second plugging member 2000, and then the second plugging member 2000 is inserted into the gap between the inner wall of the circular crystallizer copper tube and the dummy bar head. The operation plan for placing the asbestos rope 6000 is the same as above. When operating the pushing assembly 4000, after the first pushing part and the second pushing part reach the maximum limit, the first pushing part and the second pushing part do not exceed the first placement groove 1100 and the second placement groove 2100.

[0041] Specifically, as Figure 1 and Figure 8 shown, the first plugging member 1000 is in the shape of a square shell. A first movable groove 1300 is formed in the first plugging member 1000. A plurality of first round holes 1200 are provided on the first placement groove 1100. The first round holes 1200 communicate the first placement groove 1100 with the first movable groove 1300. The size of the first plugging member 1000 is approximately the same as the gap between the inner wall of the square crystallizer copper tube and the dummy bar head. The first pushing part moves in the first movable groove 1300 of the first plugging member 1000. When the pushing assembly 4000 pushes the first pushing part, one end of the first pushing part passes through the first round hole 1200 to contact and push out the asbestos rope 6000 in the first placement groove 1100, and a plurality of first round holes 1200 are evenly distributed in the first placement groove 1100 on the first plugging member 1000.

[0042] Specifically, as Figure 1 and Figure 9As shown, the second plugging member 2000 is in the shape of a cylindrical shell. A second movable groove 2300 is formed inside the second plugging member 2000. A plurality of second round holes 2200 are provided on the second placement groove 2100. The second round holes 2200 communicate the second placement groove 2100 with the second movable groove 2300. The size of the second plugging member 2000 is substantially the same as the gap between the inner wall of the circular mold copper tube and the dummy bar head. The second pushing part moves in the second movable groove 2300 of the second plugging member 2000. When the pushing assembly 4000 pushes the second pushing part, one end of the second pushing part passes through the second round hole 2200 to contact and push out the asbestos rope 6000 in the second placement groove 2100, and a plurality of second round holes 2200 are evenly distributed in the second placement groove 2100 on the second plugging member 2000.

[0043] Specifically, as Figure 2 and Figure 5 shown, the holding rod 3000 is provided with a hollow pipe 3100. An operation round hole 3200 is formed on the holding rod 3000. The operation round hole 3200 communicates with the hollow pipe 3100. The hollow pipe 3100 is respectively connected and communicated with the first movable groove 1300 and the second movable groove 2300. The transmission member is arranged inside the hollow pipe 3100. At the same time, the operation part of the transmission member passes through the operation round hole 3200 and is arranged on the outer surface of the holding rod 3000, so as to facilitate personnel to control the transmission member while holding the holding rod 3000.

[0044] Specifically, as Figure 2 and Figure 3As shown in the figure, both the first pushing part and the second pushing part include a pushing block 4110, a connecting rod 4120, and a connecting plate 4130. The pushing blocks 4110 are respectively arranged in the first placement groove 1100 and the second placement groove 2100. One end of the pushing block 4110 is connected to one end of the connecting rod 4120, and the other end of the connecting rod 4120 is connected to the connecting plate 4130. The connecting rod 4120 respectively penetrates through the first circular hole 1200 and the second circular hole 2200, and the connecting plates 4130 are respectively arranged in the first movable groove 1300 and the second movable groove 2300. Since the first sealing member 1000 and the second sealing member 2000 act on the square mold and the circular mold respectively, the structures of the first sealing member 1000 and the second sealing member 2000 are different, so that the shapes of the connecting plates 4130 in the first movable groove 1300 and the second movable groove 2300 are also different. A plurality of connecting rods 4120 passing through the first circular hole 1200 or the second circular hole 2200 are arranged on the connecting plate 4130. One end of the connecting rod 4120 is provided with a pushing block 4110, so that a plurality of uniformly distributed pushing blocks 4110 exist in the first movable groove 1300 and the second movable groove 2300, ensuring that the plurality of pushing blocks 4110 can smoothly push out the asbestos rope 6000 placed in the first placement groove 1100 and the second placement groove 2100. The cross-section of the pushing block 4110 is trapezoidal, and the long side of the bottom of the pushing block 4110 is connected to the connecting rod 4120, which is convenient for completely pushing out the asbestos rope 6000. The asbestos rope 6000 is made of a flexible heat-insulating material and has a certain deformation ability.

[0045] Specifically, as Figure 2 and Figure 6 shown, the transmission member includes a first transmission rack 4310, a second transmission rack 4320, a transmission gear 4330, and a crank 4340. The first transmission rack 4310 and the second transmission rack 4320 are both arranged in the hollow pipe 3100. One end of the first transmission rack 4310 is connected to the connecting plate 4130 in the first movable groove 1300, and one end of the second transmission rack 4320 is connected to the connecting plate 4130 in the second movable groove 2300. One end of the transmission gear 4330 is fixedly arranged in the hollow pipe 3100. The transmission gear 4330 is located below the operation circular hole 3200. One end of the crank 4340 passes through the operation circular hole 3200 and is connected to the other end of the transmission gear 4330. The other ends of the first transmission rack 4310 and the second transmission rack 4320 are arranged in an interlaced manner on the transmission gear 4330. Among them, as Figure 2 shown, a bearing is arranged at one end of the transmission gear 4330, so that one end of the transmission gear 4330 can rotate while being fixed;

[0046] When the user operates the transmission member to push out the asbestos rope 6000 in the first placement groove 1100, the transmission gear 4330 is driven to rotate counterclockwise by rotating the crank 4340 counterclockwise. The transmission gear 4330 drives the first transmission rack 4310 to move towards the first sealing member 1000. The first transmission rack 4310 pushes the first pushing portion, so that the pushing block 4110 of the first pushing portion pushes the asbestos rope 6000 in the first placement groove 1100. After the asbestos rope 6000 is pushed out, the user rotates the crank 4340 clockwise to drive the driven gear to rotate clockwise. The driven gear drives the first transmission rack 4310 to return to the initial position, thereby driving the first pushing portion to return to the initial position. The steps for the user to operate the transmission member to eject the asbestos rope 6000 in the second placement groove 2100 are the same as the above steps.

[0047] Preferably, as Figure 2 and Figure 6 shown, the other ends of the first transmission rack 4310 and the second transmission rack 4320 are alternately arranged on the transmission gear 4330. When the crank 4340 is operated to rotate the transmission gear 4330, the first transmission rack 4310 and the second transmission rack 4320 move synchronously, thereby saving the space of the hollow pipe 3100 in the grip rod 3000 and preventing the risk of bending of the grip rod 3000 during use.

[0048] Specifically, as Figure 2 and Figure 4 shown, the mold sealing dummy bar device further includes a limiting member 5000. The limiting member 5000 includes a limiting rod 5100 and a limiting spring 5200. A limiting hole 4131 is formed in the connecting plate 4130. One end of the limiting rod 5100 is fixedly connected to the first moving groove 1300 and the second moving groove 2300 respectively. A limiting spring 5200 is sleeved on the limiting rod 5100, and the limiting rod 5100 is matched with the limiting hole 4131. The first pushing portion and the second pushing portion need to be provided with a limiting member 5000 when pushing out the asbestos rope 6000 to limit the moving distance of the first pushing portion and the second pushing portion. For example, when the first pushing portion moves towards the first placement groove 1100 along with the first transmission rack 4310, at this time, the first transmission rack 4310 pushes the connecting plate 4130 to move in the first moving groove 1300. During the movement of the connecting plate 4130, the limiting rod 5100 located in the first moving groove 1300 moves in the limiting hole 4131 on the connecting plate 4130, thereby limiting the movement direction of the connecting plate 4130. At the same time, the connecting plate 4130 squeezes the limiting spring 5200 sleeved on the limiting rod 5100 during the movement. When the limiting spring 5200 is squeezed to the minimum length, at this time, the first pushing portion reaches the maximum limit, preventing the first transmission rack 4310 from disengaging from the transmission gear 4330. Similarly, the second pushing portion is provided with a limiting member 5000 with the same structure, thereby protecting the stability of the transmission member and improving the service life of the device.

[0049] Preferably, a grid-shaped gripping surface is provided on the surface of the grip rod 3000. When a user operates a crystallizer plugging dummy bar device of the present utility model, the grip rod 3000 needs to be held. High stability is required during operation. At this time, a grid-shaped gripping surface that increases friction is provided on the surface of the grip rod 3000, so that the user can reduce hand slippage during the gripping operation, thereby improving the flowability and stability of the operation.

[0050] In the description of the present utility model, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0051] The present utility model has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present utility model. It must be pointed out that the disclosed embodiments do not limit the scope of the present utility model. On the contrary, modifications and refinements made without departing from the spirit and scope of the present utility model fall within the scope of patent protection of the present utility model.
