Residual stresses have a significant effect on the durability of the work rolls of cold rolling. At a high level, and an unfavorable distribution add up to the contact and thermal stresses , which can cause premature failure of the active layer of the roll. Knowledge of the magnitude and nature of the residual stress distribution and the ability to some extent, control the process of their formation can reduce their negative impact on the durability of the rolls. This is especially important when the process of manufacture of the rolls ( quenching method , the active layer deposition , etc.) , replacing the brand roll steel. Therefore, one way to improve the reliability and durability of the work rolls of cold rolling mills is the creation of a favorable state of stress. It is shown that for determining the magnitude and distribution of residual stresses in the weld work rolls of cold rolling with a high hardness of the active layer may use a method groove.
