摘　　要：通过590L大梁钢的模拟轧制试验,对不同微合金化组合条件下钢的组织和性能进行研究。结果认为以Nb、V、Ti、B的微合金化组合,其针状铁素体+少量贝氏体的组织能够达到590L大梁钢的强韧性要求。在试验研究成果的基础上结合生产经验,通过优化成分设计和工艺方案,成功进行了工业试制,生产出合格的590L汽车大梁钢,其组织及性能完全满足用户的要求。Through under different mic rolling simulation of 590L auto beam steel, microstrueture and properties of the steel roalloying conditions are investigated. Research results show that microstructures of ac- icular ferrite and a small amount of bainite obtained from microalloying with Nb, V, Ti, and B can satisfy the strength and toughness requirements of 590L auto beam steel. According to the research results in the laboratory as well as beam steel has been production experience, successfully developed trial production has been carried out and qualified 590L auto through optimization of composition and process design. The microstructure and properties of the steel so produced can fully meet the users＇ requirements.
