摘　　要：首钢集团秦皇岛首秦金属材料有限公司(首秦公司)在X80管线钢大批量稳定生产的基础上,针对西气东输三线项目用厚壁、大板宽X80管线钢技术要求和首秦炼钢与轧钢的技术装备条件,在TMCP工艺基础上通过采用优化的控冷工艺(联合使用UFC超快冷和ACC层流冷却),降低了合金成本,获得均匀稳定的力学性能。通过对首秦西气东输三线项目5.2万t X80管线钢的成分、工艺、组织、性能进行论述及统计分析,说明采用TMCP和优化的冷却工艺(OCP)生产的X80管线钢完全满足西气东输三线对大壁厚X80管线钢热轧钢板的技术要求,并且实现了良好的成本控制。Based on mass production of X80 pipeline steel plate, it adopted the TMCP＋OCP （Optimized Cooling Process） to reduce the cost of alloy and achieve stable mechanical properties in Shougang Group Qinhuangdao Shouqin Metal Materials Co., Ltd. （SQS）, according to the technical requirements of X80 heavy wall thickness and wide steel plates for the third West-to-East Natural Gas Transmission Pipeline Project and the technology capability of steelmaking and plate mill in SQS. By describing and analyzing the composition, rolling process, microstructure and mechanical properties of 52 000 t X80 pipeline steel plates produced in SQS for the third West-to-East Natural Gas Transmission Pipeline Project, it indicated that the X80 pipeline steel plates produced by TMCP＋OCP can fully meet with the technical requirements of X80 hot rolled plates with heavy wall thickness for the third West-to-East Natural Gas Transmission Pipeline Project, and achieve a good cost control.
