摘　　要：通过合理设计X70管线钢成分,分析研究双机架轧制工艺、控冷工艺及矫直模型,同时采取标准化参数作业指导和设备改善两方面的攻关措施,成功生产出了性能合格的X70管线钢。验证结果表明,邯钢生产出的X70管线钢以粒状贝氏体组织为主,屈服强度、抗拉强度以及冲击韧性等力学性能良好,达到了标准和用户要求,产线具备进行稳定生产的能力。By reasonably designing the composition of X70 pipeline steel,analyzing and studying the double stand rolling process,controlled cooling process,and straightening model,and adopting standardized parameter operation guidance and equipment improvement measures,X70 pipeline steel with qualified performance has been successfully produced.The verification results show that the X70 pipeline steel produced by Hansteel is mainly composed of granular bainite structure,with good mechanical properties such as yield strength,tensile strength,and impact toughness,meeting the standards and user requirements.The production line has the ability to carry out stable production.
