摘要:
通过对X80M钢级1 219 mm×33 mm大壁厚管线钢管千吨级的试制,总结了大壁厚管线钢管开发的技术特点。采用超低C,控Mn,Nb和Ti微合金化成分设计和轻压下、热机械控制工艺(TMCP)超快冷等工艺控制措施,国内首次批量开发出了X80M钢级33 mm大壁厚管线钢。其母材微观组织为细小针状铁素体加弥散粒状贝氏体。通过制管后检测,母材及焊缝的拉伸性能、冲击韧性和止裂性能等完全满足陕京四线工程的要求。
Abstract:
Through kiloton trial production for X80M ?准1 219 mm×33 mm pipeline steel pipe, it summarized the technical characteristics of line pipe with heavy wall thickness. By the use of ultra-low C, control Mn, Nb, Ti micro-alloying composition design and soft reduction, TMCP ultrafast cold and other control measures, the X80 pipeline steel with 33 mm thickness was developed firstly in China domestic. The microstructure of base metal consists of small timber acicular ferrite and diffuse granular bainite. Through the detection, the tensile properties, impact toughness of base metal and?weld, crack arrest performance fully meet the rigorous requirements of NO.4 Shaanxi Beijing pipeline project.
