How to prevent the harm of rollers and improve work efficiency?

The working conditions of the rollers in the rolling mill components are relatively chaotic. Residual stress and thermal stress may occur during the preparation process before production and use of the roller. During application, it is further subjected to various cyclic stresses, including twists and turns, modifications, shear forces, contact stresses, and thermal stresses. The distribution of these stresses along the roll body is uneven and constantly changing, not only due to planning elements, but also to the continuous changes in wear, temperature, and roll shape during the use of the roll. In addition, rolling conditions often exhibit abnormal conditions. Improper cooling of the roller after use can also cause harm from thermal stress. So in addition to wear and tear, the rollers often exhibit various damages such as cracks, cracking, detachment, and indentation, as well as external damage.
