| 摘 要： | 冷轧马氏体钢主要用于汽车安全件,成形以冷弯或辊压为主,因此,马氏体钢的冷弯性能至关重要。以宝钢工业产线轧制的980 MPa级冷轧马氏体钢为研究对象,研究了不同S含量水平和Ca处理对冷轧马氏体钢弯曲性能的影响,分析了不同S含量水平下钢中的夹杂物数量和级别。通过控制S含量和采用Ca处理,可以明显降低马氏体钢中的夹杂物数量、尺寸,最终明显提高冷弯性能。宝钢开发的980 MPa级冷轧马氏体钢已经成功应用于乘用车安全部件的制造。

| Abstract: | Cold-rolled martensitic steels are mainly applied to the production of automobile safety parts.As the steel is always roll-formed or cold-bended during the forming,the cold bending property is very important to this steel.Taking the 980 MPa martensitic steel sheets produced by Baosteel as the study object,the authors of this paper investigated the effect of sulfur content and calcium modification on the bending property of cold-rolled martensitic steels.They also analyzed the number and degree of inclusions... |
