摘　　要：针对油气输送中对抗硫管线管抗HIC性能要求和调质态无缝管线管的生产特点,着重对调质态无缝管线管组织控制影响因素进行了分析,采用试验验证了化学成分、热处理工艺等对无缝管线管调质态组织的影响,并结合不同组织状态对其抗HIC性能的影响,分析了调质态抗硫无缝管线管最合适的组织控制状态。研究表明,通过调整合金成分,并搭配合理的热处理工艺,可控制获得均匀细小的回火B+F组织,从而有效提高无缝管线管抗HIC性能。According to the anti-HIC requirements and manufacturing characters of sulfur resistent seamless line pipe, investigation is focused on the factors that affect Q＆T seamless line pipe＇s microstructure. By using numbers experiment to verify the chemical compositions and how heat treatment affect Q＆T seamless line pipe＇ s microstructure. Also studied effect of different microstructures on HIC resistance and analyzed preferred microstructure state of Q＆T seamless line pipe. The research shows by controlling alloy compositions and combining with appropriate heat treatment process can get a fine tempered B ＋ F microstructure, which can effectively improve HIC resistance of seamless line pipe.
