摘　　要：针对宝钢不锈钢公司冷连轧SUS430不锈钢在深拉伸后表面存在严重的起皱问题,详细分析了影响430铁素体不锈钢表面起皱的因素。通过化学成分优化、浇注过程采用电磁搅拌和热轧、热处理及冷轧工艺改进,使430不锈钢制品在冲压后的起皱缺陷得到改善,提高了材料的机械性能,并开发出含低Ti与Nb的低起皱铁素体新产品,使抛光成本下降。For the serious ridgging problem of 430 cold product after deep drawing by tandem rolling in Baosteel Stainless Steel Co. , Ltd. , the factors influencing surface ridging of 430 ferritic stainless steel are analysised in detail. Through optimizing component, electromagnetic stiring of casting, improving hot rolling, hot annealing and cold rolling technology, the ridgging defect of 430 cold product by tandem rolling is improved after deep drawing, and the mechanism performance is increased. The low-ridgging ferritic stainless steel is developed, which can make the polishing cost decrease.
