摘　　要：针对某平整机支承辊表面出现的裂纹,对支撑辊进行硬度测试和探伤检测,分析检测结果,并结合轧机使用情况,确定了带钢甩尾是裂纹产生的主要原因,并提出了处理方法和预防措施。Hardness test and flaw detection of the backup roll were performed for solving the problem of cracks occurring on the surface of the backup roll on a temper mill. The detection results, combined with the service condition of the rolling mill, indicated that strip wrapping arounded the work roll was the main reason for cracks. The handling methods and prevention measures were put forward.
