摘　　要：介绍了邯钢冷轧厂重卷线啃伤缺陷的特征,分析了产生缺陷的影响因素。认为其缺陷产生的根本原因是带钢的层间滑移,并与开卷张力、带钢运行速度等有关。采取相应的改进措施后取得了良好效果。The feature of scratch defect of strip during recoiling was introduced. The influence factors were analyzed. The conclusion showed that the sliding between strip layers, tension and strip running speed were the main factors to produce this defect. Therefore, the countermeasures were put forwcord and good effects were obtained.
