Through fracture and service analysis it is verified that the primary factor that causes spalling failures of the back up roll of cold strip HC mill for six times is heavier roll contact pressure imposed upon the contacting surface between the back up roll and the intermediate roll shoulder which tends to initate an edge fatigue espocially in the case of excessively lesser roll grinding and much heavier roll reduction. Corrective action is correspondingly provided.
