[0002] Iron and steel smelting is a general term for the metallurgical processes of steel and iron. Industrially produced iron is classified into pig iron and steel based on its carbon content. Iron and steel smelting requires the rolling of steel billets. Billet rolling refers to the process of rolling steel ingots into slabs, billets, and irregularly shaped billets on a primary rolling mill, thereby breaking down the casting structure of the ingot. Steel billet rolling is a new process and technology that has emerged in recent years based on the development of continuous casting technology. It involves rolling continuously cast steel billets, while they are still hot from the continuous casting machine, into billet mills without reheating or with only slight compensation heating, to form steel billets or directly into finished steel products.

Frame two is welded to one end of the panel, and frame one is welded to the end of the panel facing away from frame two. A rotating shaft is sleeved inside both frame one and frame two. A partition is welded to the top surface of the panel, and a drive motor is installed on the rear end surface of the partition. A roller is installed on the output shaft of the drive motor. A shell two is welded to the top surface of frame two, and an electric heating wire is fitted to the inner wall of shell two. A shell one is welded to the top surface of frame one, and a gas collecting hood is embedded and fixed to the bottom surface of frame one. A water storage tank is installed on the bottom surface of frame one via a mounting bracket, and a coil is installed inside the water storage tank.

[0004] When in use, it rolls the steel billet through the rollers. However, the rollers are inconvenient to disassemble and assemble, which makes later maintenance inconvenient. Without proper maintenance for a long time, steel clamping is prone to occur during use. Therefore, it is necessary to design a steel clamping device for the R2 vertical rollers in roughing mill to solve the above problems.

[0032] The frame 1 is equipped with a rolling mill mechanism. It should be noted that the rolling mill mechanism allows for quick and easy removal of the roughing mill R2 vertical roll 3 for maintenance after a period of use, which can effectively prevent the occurrence of steel clamping.

[0033] The rolling mechanism includes I-beam block 2, roughing R2 vertical roll 3, hydraulic cylinder 9, push block 10, connecting piece 11 and limiting bar 13;

[0034] The I-shaped block 2 is engaged with the two corresponding push blocks 10, and the roughing R2 vertical roll 3 is rotatably mounted on the I-shaped block 2. It should be noted that two roughing R2 vertical rolls 3 are rotatably connected to one I-shaped block 2.

[0035] The hydraulic rod of the hydraulic cylinder 9 is fixedly connected to the push block 10 below. The connecting piece 11 is fixedly installed between two adjacent push blocks 10. The limiting strip 13 is fixedly installed on the frame 1 and abuts against the I-shaped block 2.

[0036] By activating the hydraulic cylinder 9 through the aforementioned rolling mechanism, the pusher block 10 can move the I-shaped block 2 downwards, thus separating the I-shaped block 2 from the limiting strip 13. At this time, the two I-shaped blocks 2 in front can be pulled forward to remove the two roughing R2 vertical rolls 3 in front, and the two I-shaped blocks 2 in the back can be pulled backward to remove the two roughing R2 vertical rolls 3 in the back. This allows for convenient and quick removal of the roughing R2 vertical rolls 3 for maintenance, effectively preventing the occurrence of steel clamping.

[0037] Specifically, the rolling mechanism also includes a top plate 4, a servo motor 5, a rotating shaft 6, and a connector 7. The top plate 4 is fixedly installed on the frame 1, and the servo motor 5 is fixedly installed on the top plate 4. It should be noted that the servo motor 5 is controlled by an external controller, which can ensure the coordination of the work of each servo motor 5.

[0038] The output end of the servo motor 5 is fixedly connected to the rotating shaft 6, and the plug 7 is fixedly installed on the top of the roughing R2 vertical roll 3. The plug 7 is engaged with the rotating shaft 6.

[0039] Through the aforementioned rolling mechanism, the servo motor 5 is started, and the rotating shaft 6 can drive the roughing R2 vertical roll 3 to rotate through the connector 7 to roll the steel billet. When the I-shaped block 2 moves down, the roughing R2 vertical roll 3 can drive the connector 7 to move down, so that the connector 7 can be moved off the rotating shaft 6.

[0040] Specifically, a base plate 8 is fixedly installed on the frame 1, and a hydraulic cylinder 9 is fixedly installed at the bottom of the base plate 8. It should be noted that the hydraulic cylinder 9 is assembled.

[0041] Specifically, a T-shaped hole 12 is provided on the front side of the push block 10, and the I-shaped block 2 is engaged with the T-shaped hole 12. The two corresponding I-shaped blocks 2 are in contact with each other on their closest sides, and the limiting strip 13 is in contact with the push block 10. It should be noted that this can fix the I-shaped block 2 in the T-shaped hole 12 on the push block 10.

[0042] Specifically, the bottom of the rotating shaft 6 is in contact with the roughing mill R2 vertical roll 3. The rotating shaft 6 has multiple insertion holes, and the insertion piece 7 is engaged with the insertion holes. It should be noted that this allows the rotating shaft 6 and the roughing mill R2 vertical roll 3 to rotate synchronously.

[0043] Working principle:

[0044] S1: Start the servo motor 5. The rotating shaft 6 can drive the roughing mill R2 vertical roll 3 to rotate through the plug-in piece 7 to roll the steel billet. When maintenance of the roughing mill R2 vertical roll 3 is required, start the hydraulic cylinder 9. The hydraulic cylinder 9 drives the lower push block 10 to move down. The lower push block 10 drives the upper push block 10 to move down synchronously through the connecting piece 11. The push block 10 drives the I-shaped block 2 to move down. When the I-shaped block 2 moves down, the roughing mill R2 vertical roll 3 can drive the plug-in piece 7 to move down. In this way, the plug-in piece 7 can be moved off the rotating shaft 6 until the I-shaped block 2 is separated from the limit strip 13.

[0045] S2: Pull the two I-shaped blocks 2 forward to remove the two front roughing R2 vertical rolls 3, and pull the two rear I-shaped blocks 2 backward to remove the two rear roughing R2 vertical rolls 3. This makes it easy and quick to remove the roughing R2 vertical rolls 3 for maintenance, which can effectively prevent the occurrence of steel jamming.
