Introduction to rolls
01-03-2023
The roll is the main working part and tool to produce continuous plastic deformation of the metal on the mill. The roll is mainly composed of 3 parts: the roll body, the roll neck and the shaft head. The roll body is actually involved in rolling the metal in the middle of the roll. It has a smooth cylindrical or grooved surface. The roll neck is mounted in a bearing, and the rolling force is transmitted to the frame through the bearing housing and the press down device. The drive end shaft head is connected to the gear block by a connecting shaft, which transmits the motor's turning torque to the roll. The rolls can be arranged in the mill frame in the form of two rolls, three rolls, four rolls or multiple rolls.
