Rolls are key components in hot strip mill. Roll wear and fatigue are inevitable phenomena during hotrolling process. Finite element (FE) analysis shows that roll profiles, especially work roll wear profile, have significant effects on contact stress distributions. Longterm effect of huge contact stress peaks in roll sides is the main factor for roll spallings. In order to solve serious roll ...
