冷轧镀锌线带钢翘曲产生原因及解决方案

Reasons and Solutions for the Warping of Cold-rolled Galvanized Strip Steel

某冷轧厂镀锌机组在生产过程中发现,2#卷取机下线钢卷存在纵向翘曲缺陷。本文主要介绍了针对该质量缺陷问题,通过理论计算分析,查找纵向翘曲产生的原因,同时结合现场工况提出并实施了改造方案,最终解决了2#卷取机下线钢卷翘曲缺陷,使带钢质量得到了有效提升。

During the production process of a galvanizing unit in a certain cold rolling plant,it was found that the steel coils of the 2#coiler had longitudinal warping defects.This article mainly introduces the problem of quality defects.Through theoreti⁃cal calculation and analysis,the cause of longitudinal warping is identified.At the same time,a renovation plan is proposed and implemented based on on-site conditions,ultimately solving the warping defect of the steel coil in the offline production of the 2#coiler,effectively improving the quality of the strip steel.
