[0002] In the process of section steel production, there is a long transmission distance between rough rolling and finish rolling. After rough rolling, the steel needs to pass through a guide system to ensure that the steel can correctly enter the high-pressure water descaling link. At the end of rough rolling, the temperature of the steel is usually above 1000 degrees Celsius. Therefore, effective cooling measures must be taken before entering the high-pressure water descaling. The guide wheel is a key component in the steel production line, and its main function is to guide the steel to the correct processing path. However, due to the high temperature of the steel, the guide wheel faces extremely severe challenges during operation. High temperature can cause the guide wheel to overheat, which in turn can cause a series of problems. Guide wheel overheating not only affects the quality of the steel, which can cause scratches on the surface of the steel, but also causes excessive wear of the guide wheel itself, increasing its replacement frequency and maintenance costs, thereby affecting production efficiency and reducing the service life of the equipment.
