Additionally the roll is subjected to Thermal and Mechanical Fatigue during rolling:

Cold Rolling Mill Temperature Measurement Williamson

At the cold mill the rolls and strip become heated through the heat of deformation. As the rolls heat they expand. If the middle of the roll heats more than the edge, then thermal crowning occurs, and the strip thickness will vary across the width.Cold Mill an overview ScienceDirect Topics,John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 7.17 Reduction of Local Buckles. Even though the cold mill itself may cause local buckles, the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al., 2006). Therefore, proper monitoring of the hot band profile and mechanical properties will be the first choice to reduce local buckles.

Induction slab heating in a hot rolling process SMS
