Wear of Rolls in Single-Stand Temper Mill and Its Effect on the Strip Shape

The actual contours and wear condition of work roll and backup roll in single-stand temper mill were investigated. The effects of roll contours on strip profile were analyzed by a finite element model for computation of the roll gap profile with its quadratic and quartic components. The results show that the work roll wear is slight but the original roll contour is liable to result in quarter buckle sheet defect; non-uniform wear of backup roll is serious but has little effect on strip profile.
