摘　　要：冷轧BN1G不锈钢主要应用在装饰板和家用电器等方面,除了需要满足力学性能要求外,还要求钢板表面光洁度好,不能有表面缺陷,冲压不能断裂。经近二年不等时间的跟踪统计,发现冷轧BN1G钢板的表面质量主要由前期热轧后酸洗引起的氧化皮残留、酸洗花斑、酸洗花纹、色差等缺陷,而机械损伤引起的表面缺陷较少。因此,主要分析了酸洗引起的表面缺陷的起因,并给出了相应解决办法。Cold rolled BN1G stainless steel sheets are mainly used in decorative plate and home electric appliance etc. , and thus in addition to the requirement of mechanical properties, the stainless sheets are required to have good surface finish, no surface defects and no stamping fracture etc. By trace statistics for different times in near two years, it was found that the surface defects of cold rolled BN1 G steel sheets, such as pickling oxide skin residues, pickling spots, pickling patterns, color difference, were mainly from pickling process of hot rolled steel sheets before cold rolling, while the probability of mechanical damage was relative low. Therefore, the origins of the surface defects during pickling process were analyzed, and the corresponding resolving methods were given.
