摘　　要：根据高强度磁轭钢的特点和要求,介绍了武钢开发800 MPa级磁轭钢的微合金化成分设计及控轧控冷技术,以及该钢的组织形态和析出相分布与形貌。经检测,产品的力学性能、磁性能良好,满足大型水电项目用磁轭钢的制造要求。According to the characteristic and demand of high strength rim sheet,the Nb-Ti microalloying chemical composition design and TMCP technology for 800 MPa grade rim sheet steel of WISCO were introduced. The microstructure and the distribution of precipitation were observed. The results show that the tensile and magnetic properties of this steel are good enough for rim sheet needed.
