摘　　要：结合唐山钢铁集团公司超低硫管线钢试验生产实践,介绍了全流程硫含量控制技术,指出了超低硫冶炼的关键控制点在铁水预处理和精炼,抗氢致裂纹的关键在于钢中夹杂物的控制。得出了通过全过程硫含量控制能够生产超低硫管线钢的结论。Based on the testing practice of extra-low pipe line steel in tanggang, the pres- ent paper introduces the technology of sulfur control in the overall process, points out that the key control points for refining the extra-low steel are hot metal pretreatment and LF refining,and key to HIC resistance is to control inclusions in steel. It＇s concluded that by controlling the sulphur content in the entire process the extra-low sulphur pipe line steel can be produced.
