Among the rolling mill components, the operating conditions of the rolls are the most messy. Residual stress and thermal stress will occur in the preparation process before the roll is manufactured and used. During the working process, it is further subjected to the effects of various periodic stresses, including twists, changes, shear forces, contact stresses, and thermal stresses.
