The metallurgical roll is an essential part of the metal roll forming machine. It is used as a special tool to make the metal deform plastically and roll out various rolled products.
Due to the special conditions of the rolls, large consumption and closely related to the quality and cost of the rolled material, high requirements are placed on the performance of the rolls. This makes roll manufacturing an independent industry, and many roll manufacturers continue to conduct in-depth research on roll materials, manufacturing processes and performance to meet various use needs.
Rolls are different from general structural parts, and the working conditions are complex and diverse. During the rolling process, the roll body must bear high stress, mainly bending stress and friction, etc., and the main drive roll must also bear huge torque.
The surface of the roller body has to withstand friction, wear, impact, contact stress and fatigue caused by intense cooling and heat for a long time.
