摘　　要：介绍了高强度线材发展趋势,在SWRS82B线材的基础上,通过合金成分设计研发出了SWRS92Si线材,经过盐浴热处理后其强度超过1500 MPa,再经过拉丝和热镀锌,钢丝抗拉强度达到了2160 MPa及以上,并研发出在线盐浴装备,使其能大批量生产应用于实际。This paper introduces the development trend of high strength steel wire rod,on the basis of SWRS82B steel wire rod,through the alloy composition design developed SWRS92Si wire,its strength after salt bath heat treatment more than 1500 MPa,again through drawing and hot dipped galvanized,steel wire tensile strength reached 2168 MPa and above,and the development of the salt bath equipment online can make the mass production in practice possible.

关 键 词：线材 盐浴热处理 桥梁缆索
