摘　　要：介绍了近年来武钢管线钢生产技术及产品研发的主要成果。采用独特的控轧控冷(STMCP)技术,成功开发出厚规格海底管线钢和X80钢级抗大变形管线钢;掌握了耐冲蚀磨损的机理,成功开发出长距离煤浆输送用WJ65钢;创建专有的成分和生产工艺,实现了连续油管用钢、超大输气量高压管道工程用X90钢级管线钢、高频电阻焊管用K55钢的工业生产。Elaborated in the article are the major achievements of R ＆ D of manufacturing technologies for and products of steels for line pipe-making in Wuhan Iron and Steel （Group） Corp. Thanks to employment of the STMCP technique, the steel for heavy wall off-shore pipe line service and anti-large deformation linepipe-purpose X80 steels are developed successfully. And owing to the mastery of the mechanism of erosion/wear resistance, the WJ65 steel for pipe line for long-distance coal slurry transport is also successfully produced. Furthermore, with know-how about relevant chemical composition and manufacturing process, the company is capable of commercial production of such products as the steel for coiled tubing, the X90 steel for hi-pressure gas pipeline system with extra-capacity, and the K55 steel for HFW pipes.
