Rolling mill roller is the main working part and tools on the rolling mill that cause continuous plastic deformation of the metal. The roll is mainly composed of three parts: roll body, roll neck and shaft head. The rolling mill roller 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 the rolling force is transmitted to the stand through the bearing seat and the pressing device. The shaft end of the transmission end is connected with the gear seat through the connecting shaft, and transmits the rotating torque of the motor to the roller. The rolls can be arranged in the form of two-roll, three-roll, four-roll or multi-roll in the rolling mill stand.
