Understanding Thermal Fatigue Cracking in Section Mill Rolls
Thermal fatigue cracking, commonly referred to as fire cracking, is one of the most frequent degradation mechanisms encountered in heavy section steel mill rolls during hot rolling operations. Under intense cyclic heating from the hot steel sections and rapid cooling via water headers, the roll working layer expands and contracts alternatively, creating massive thermal stresses […]
