When processing the roll, the roll has a high temperature when it is taken out of the furnace, and in order to improve the strength of the roll, the roll needs to be cold treated. In the process of cooling the roll, due to the characteristics of the metal, too fast cooling speed will cause stress concentration and metal deformation. Therefore, the temperature of the roll needs to be gradually reduced. When cooling by water cooling, it is easy for the water temperature to be relatively fixed and low, resulting in the roll cooling speed being too fast. Utility Model Content
