摘　　要：介绍包钢CSP生产线开发矿浆输送管用X65管线钢的情况。采用Nb含量达0.065%的微合金化成分设计及控轧控冷工艺,生产出厚度为11.0～12.7 mm的厚规格X65管线钢5 000余t,未出现常见的混晶现象,钢带的组织、性能优良,满足AP15L制管要求。所制成的1.2万m钢管现场打压一次成功。slurry in Baogang An industrial experiment of developing X65 pipeline steel for iron concentrate CSP line was introduced. With more than 0.065% Nb Microalloyed, 5 000 t X65 pipeline steel of the thickness 11.0 - 12.7 mm was produced by TMCP process. The steel was com- posed of fine and uniform structures, showing good performance and excellent toughness, which could meet the AP15L requirements of pipeline manufacture. The hydrostatic test to 12 000 m pipeline made of the steel was successful.
