摘要
本文对冷轧重分卷错层划伤缺陷原因进行了分析,得出此缺陷是由于开卷机胀缩缸旋转接头密封不严而产生内泄所致。采取了以机械密封方式替代斯特封密封的措施,划伤缺陷基本消除。
the cause of stagger cascade scratch defect while re-coiling of cold rolled strip was analysed,the result showed that the defect was induced by interior leaking of expansion and contraction cylinder because of seal inadequate of revolving joint.Stepseal was replaced by mechanical seal,and The defect was eliminated.
