Description

Technical Field

[0001] This utility model relates to the field of billet continuous casting machines, and more specifically, to a high-speed billet continuous casting machine. Background Technology

[0002] The continuous casting machine is a key piece of equipment for continuously casting molten steel into billets. It is widely used in steel production. Its core process is as follows: after steel is tapped from the steelmaking furnace, the molten steel is distributed to the crystallizer through the tundish. In the crystallizer, it initially solidifies into a billet shell. Then, the billet is pulled out of the crystallizer by the straightening machine, further cooled and hardened in the secondary cooling zone, and finally cut into fixed-length billets by the cutting equipment. Continuous casting machines are classified according to the type of crystallizer, such as arc-shaped, vertical, and horizontal. They can produce various cross-sections such as square billets, slab billets, and round billets. They have advantages such as improving metal yield, reducing energy consumption, and shortening the production process. They are the core equipment for realizing continuous and automated production in the modern steel industry.

[0003] After steel billets are produced, they need to be weighed to ensure uniform weight. Most existing weighing methods require placing the steel billets on separate weighing equipment. This method cannot be connected to subsequent transmission equipment during steel billet transportation, resulting in slow production efficiency. For example, Chinese utility model patent CN218002687U can perform flow weighing of steel billets by setting guide rollers. However, adjusting the roller spacing and disassembling and replacing the rollers requires turning the locking nut multiple times, resulting in slow adjustment and replacement speeds and certain inconveniences. In view of this, we propose a high-speed continuous casting machine for steel billets. Utility Model Content

[0004] The purpose of this invention is to solve the problem that adjusting the roller spacing and disassembling and replacing the rollers requires turning the locking nut multiple times, resulting in a slow adjustment and replacement speed.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a high-speed continuous casting machine for steel billets, comprising a weighing device body, an mounting base plate on the upper surface of the weighing device body, a sleeve fixedly connected to the upper surface of the mounting base plate, a support leg slidably fitted inside the sleeve, a mounting frame fixedly connected to the upper end of the support leg, an mounting groove on the upper surface of the mounting frame, a slot extending from the lower surface of the mounting frame on the bottom wall of the mounting groove, a mounting block movably connected inside the mounting groove, a rotating shaft fixedly connected between two mounting blocks, a roller rotatably fitted on the outer surface of the rotating shaft, a locking block fixedly connected to the lower surface of the mounting block, the lower surface of the locking block being tapered, and a locking component on the mounting frame.

[0006] As a preferred technical solution of this application, the locking component includes a pressure plate, which is rotatably connected to the mounting bracket, and the upper surface of the pressure plate is provided with an embedding groove.

[0007] As a preferred technical solution of this application, a fixing bolt is provided inside the embedding groove, and the lower end of the fixing bolt is threaded through the interior of the mounting bracket.

[0008] As a preferred technical solution of this application, the bottom wall of the mounting groove is provided with a scale indicator.

[0009] As a preferred technical solution of this application, a threaded post is fixedly connected to the upper surface of the mounting base plate, and a threaded sleeve is threaded on the outer surface of the threaded post.

[0010] As a preferred technical solution of this application, the outer surface of the threaded sleeve is provided with friction texture, and a rotating disk is fixedly connected to the lower surface of the threaded sleeve.

[0011] As a preferred technical solution of this application, a movable sleeve is rotatably connected to the lower surface of the rotating disk, and a sliding groove extending into the sleeve is opened on the outer surface of the sleeve, and a connecting rod is fixedly connected to the support leg.

[0012] As a preferred technical solution of this application, the end of the connecting rod extends out of the sleeve through a sliding groove, and the end of the connecting rod is fixedly connected to the movable sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. It can quickly fix multiple sets of rollers with the help of the pressure plate. Similarly, it can also disassemble multiple sets at the same time, reducing the operation steps during disassembly, replacement and adjustment, improving the adjustment speed, and can achieve uniform spacing between multiple sets of rollers with the help of scale indicators.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A high-speed continuous casting machine for steel billets includes a weighing device body 1. A mounting base plate 2 is provided on the upper surface of the weighing device body 1. A sleeve 3 is fixedly connected to the upper surface of the mounting base plate 2. A support leg 4 is slidably fitted inside the sleeve 3. A mounting frame 5 is fixedly connected to the upper end of the support leg 4. A mounting groove 6 is opened on the upper surface of the mounting frame 5. A slot 7 extending from the lower surface of the mounting frame 5 is opened on the bottom wall of the mounting groove 6. A mounting block 8 is movably connected inside the mounting groove 6. A rotating shaft 9 is fixedly connected between the front and rear mounting blocks 8. A roller 10 is rotatably fitted on the outer surface of the rotating shaft 9. A locking block 11 is fixedly connected to the lower surface of the mounting block 8. The lower surface of the locking block 11 is tapered. A locking component is provided on the mounting frame 5.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the locking assembly includes a pressure plate 12, which is rotatably connected to the mounting frame 5. An embedding groove 13 is provided on the upper surface of the pressure plate 12. A fixing bolt 14 is provided inside the embedding groove 13. The lower end of the fixing bolt 14 is threaded through the interior of the mounting frame 5. A scale indicator 22 is provided on the bottom wall of the mounting groove 6. Multiple sets of fast fixing can be completed with the help of the pressure plate 12. Similarly, multiple sets can be disassembled at the same time during disassembly, reducing the operation steps during disassembly, replacement and adjustment, improving the adjustment speed, and can be used with the scale indicator 22 to achieve uniform spacing between multiple sets of rollers 10.

[0031] Example 2

[0032] The high-speed billet continuous casting machine provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, a threaded post 15 is fixedly connected to the upper surface of the mounting base plate 2. A threaded sleeve 16 is threadedly fitted onto the outer surface of the threaded post 15. Friction grooves 17 are formed on the outer surface of the threaded sleeve 16. A rotating disk 18 is fixedly connected to the lower surface of the threaded sleeve 16. A movable sleeve 19 is rotatably connected to the lower surface of the rotating disk 18. A sliding groove 20 extending into the inner surface of the sleeve 3 is formed on the outer surface of the sleeve 3. A connecting rod 21 is fixedly connected to the support leg 4. The end of the connecting rod 21 extends out of the sleeve 3 through the sliding groove 20. The end of the connecting rod 21 is fixedly connected to the movable sleeve 19. The vertical movement of the threaded sleeve 16 can indirectly drive the support leg 4 to move, thereby adjusting the height of multiple sets of rollers 10 so that multiple sets of devices can be arranged side by side with height alignment. At the same time, continuous weighing avoids the difficulty of single weighing in meeting the high-speed testing requirements of traditional structures.

[0033] Meanwhile, this high-speed billet continuous casting machine can achieve precise adjustment and real-time monitoring of equipment parameters by comprehensively optimizing the automatic liquid level equipment, crystallizer vibration parameters, secondary cooling system, roller conveyor, and hydraulic system during operation. It adopts advanced sensor technology, data analysis algorithms, numerical simulation, and intelligent control algorithms to reduce vibration marks, improve the internal quality of the billet, and establish a comprehensive evaluation index system and big data analysis model for auxiliary material performance to predict the optimal combination of auxiliary material components under different production conditions. Through real-time online monitoring technology, it ensures the stability of auxiliary material performance during use, thereby improving billet quality and reducing production costs.

[0034] The high-speed continuous casting machine for steel billets provided by this utility model is used as follows:

[0035] When it is necessary to adjust the spacing of the rollers 10, the fixing bolts 14 can be removed, and then the pressure plate 12 can be rotated to release the pressure on the mounting block 8. Then, the mounting block 8, along with the rotating shaft 9 and the rollers 10, can be lifted, and the locking block 11 on the mounting block 8 can be placed into the corresponding slot 7 with the help of the scale indicator 22. During the placement process, the cone shape on the lower side of the locking block 11 plays a positioning role. After placement, the pressure plate 12 can be reset, and then the fixing bolts 14 can be tightened to lock it. When disassembling and maintaining the rollers 10, the pressure plate 12 can also be lifted for operation. At the same time, when adjusting the height of the rollers 10, the threaded sleeve 16 can be rotated. The rotation of the threaded sleeve 16, in conjunction with the threaded column 15, can achieve vertical movement. This, in turn, can be combined with the rotating disk 18 to drive the movable sleeve 19 to move vertically. The movable sleeve 19, in conjunction with the connecting rod 21, can drive the support leg 4 to move, thereby driving multiple sets of rollers 10 to move synchronously. The vertical self-locking of the threaded sleeve 16 can also prevent the support leg 4 from falling naturally.
