The roll is mainly composed of three parts: the roll body, the roll neck and the shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The shaft head at the transmission end is connected to the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roll. The roll can be arranged in the form of two rolls, three rolls, four rolls or more rolls in the rolling mill frame, and the finishing roll has a higher speed. The final rolled product must have a certain surface quality. The main requirements for it are hardness and wear resistance, and then the wear resistance of the roll should be considered when it is used. Since the wear mechanism of the roll is very complex, including mechanical stress, thermal action during rolling, cooling action, chemical action of the lubricating medium and other effects, there is no unified indicator for comprehensively evaluating the wear resistance of the roll.

[0003] However, it still has some disadvantages. For example, the metallurgical rollers are prone to increased brittleness due to strong cooling during use, which makes the metallurgical rollers very brittle and has a higher chance of roller breakage during use, increasing the risks associated with the working process. In addition, the structure of the protective device is complex, and the installation steps are cumbersome during use, which is not conducive to use.
