| Abstract: | Based on the testing practice of extra-low pipe line steel in tanggang,the present 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. |
