冷轧带钢边部折皱缺陷的成因分析与控制措施

Causes Analysis of Edge Wrinkle Defect of Cold Rolled Strip and Its Control Measures

针对首钢迁钢公司冷轧生产中带钢边部折皱缺陷,对其形成原因和机理进行了分析,认为带钢边部相对增厚是其主要原因,而热轧来料局部高点和冷轧工作辊轴向横移不当也是带钢边部增厚产生的原因。因此,提出了相应的控制措施,取得了较好效果。

In view of edge wrinkle defect of cold rolled strip produced by Shougang Qiansteel, its formation causes and mechanism were analyzed, and found out that the edge thickness adding was the main reason. Meanwhile, it pointed out that local over thickness points of hot rolled strip and unreasonable shiftting of work roll of cold mill were main reason to produce edge thickness adding. Therefore, the countermeasures were put forward, and good effects were obtained.
