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, changes, 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 factors, 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 rolls after use can also cause harm from thermal stress. So in addition to wear and tear, rolling rolls often exhibit various types of damage such as cracks, fractures, peeling, and indentations, as well as external damage. A good roller should have a good match between its strength, wear resistance, and various other performance indicators.
In this way, not only is it durable under normal rolling conditions, but it can also cause minimal damage in certain abnormal rolling conditions. So when making rolls, it is necessary to strictly control the metallurgical quality of the rolls or supplement it with external measures to enhance the load-bearing capacity of the rolls.
