酒钢不锈钢冷轧铬钢酸洗线产品粗糙和白块压入缺陷原因分析

The Cause Study on the Rough Surfaceand White Block Press-in Defects of Pickling Line for Cold Rolling Chromium Steel

酒钢不锈钢冷轧铬钢线自年初投产以来所生产出的带钢品质较差,集中体现在表面粗糙和白块压入缺陷。本文针对两种缺陷,取样、优化设备功能、调整酸洗工艺等一系列措施,使得产品表面酸洗均匀,整体品质得以提升。

Since the cold-rolled chromium steel line was put into production in JISCO stainless steel plant at the beginning of the year,the poor quality of the produced steel strip is mainly reflected in the defects of rough surface and white block press-in.In the paper,a series of measures are taken to solve the two defects by sampling,optimizing the equipment function,adjusting the pickling process etc.which make the product surface uniform and the quality improved.
