Good Quality Rolls for Rolling Mill

The main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. The roll is mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling 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 head 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.
