Cyclic temperature changes in the working layer of a roll during hot rolling cause thermal stress which leads to damage on the surface layer of the roll due to thermal fatigue. The pre-conditions of crack initiation are described. The intensity of crack propagation could be influenced by optimizing the chemical composition and physical-mechanical properties of the material on the working layer

Mechanical wear is caused by the friction between the surface of the mill roll and the rolling stock, which requires periodic grinding of the roll surface. In order to meet the process requirements of the shape control, the roll surface busbars must be processed into various special high-order square curves according to different process requirements.
