单机平整机轧辊的磨损及其对板形的影响

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

摘要: 分析了单机架平整机轧辊的实际辊形、磨损状况,并通过运用有限元模型计算辊缝曲线的2次和4次分量研究了辊形对板形的影响.结果表明,工作辊磨损较轻,对辊形影响不大,但原始辊形与目标辊形差别较大,是产生1/4浪板形缺陷的因素之一;支持辊局部磨损较严重,但这种不均匀磨损对板形影响较小,在整个服役期内对板形的作用基本不变.

Abstract: 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.
