The main functions of the guides include guiding and stabilizing the movement of the steel sheet, ensuring that the sheet accurately enters the rolling mill and controlling its position and tension during rolling, thereby preventing deflection and warping. The existing guide and guard device generally consists of a guide plate, a guide roller and an adjusting mechanism, and the smooth proceeding of the rolling process is ensured by accurately guiding the steel plate into the rolling mill and controlling the position of the steel plate. The guide structure is an important component in the guide device, is generally directly fixed on a mill housing through bolts, and provides powerful support for the guide device by utilizing the guide structure to prevent the guide device from lateral displacement and vibration, so that accurate guide and stable support of the steel plate are realized. However, in hot rolled strip production lines, particularly in roughing reversing mills, excessive head tilting of the slab is often caused due to uneven heating of the slab and excessive reduction in the rolling process, which in turn causes the slab to strike the guides. In this case, an impact force generated instantaneously acts on the guide structure through the guide device, so that the bolts connected with the guide structure are elongated or broken, and the guide accuracy of the guide structure is lowered. This not only results in lateral displacement and vibration of the guides and guards, but also causes mill downtime. Because the current guide structure is generally in an integral type, the guide structure needs to be integrally disassembled when the guide structure is maintained, thereby increasing the maintenance workload and reducing the maintenance efficiency. Therefore, how to improve the guiding structure to improve the maintenance efficiency is a technical problem to be solved.
