Single hook rubber breaking roll is one of the rolls, and the working conditions of the rolls in the rolling mill parts are more chaotic. Residual stress and thermal stress will occur in the preparation process before roll manufacturing and application. When it is used, it is further subjected to the effects of various periodic stresses, including bending, modification, shear, contact stress and thermal stress.
The distribution of these stresses along the roll body is uneven and constantly changing. The reason is not only the planning elements, but also the continuous changes of roll wear, temperature and roll shape. In addition, rolling conditions often show anomalies. If the roll is not cooled properly after use, it will also be damaged by thermal stress. Therefore, in addition to wear, the roll often presents various partial hazards and surface hazards such as crack, crack, drop, indentation and so on.
A good roll should have a better match between its strength, wear resistance and other performance indexes. In this way, it is not only durable under normal rolling conditions, but also less harmful in some abnormal rolling conditions.
