| Abstract: | In order to improve the ability of HIC-resistance and SSCC-resistance of the pipeline steel in the environment with high hydrogen sulfide（H2S）,and to avoid crack caused by corrosive gas,hydrogen content in steel are analyzed.Reduce the slag material addition amount under the steel tapping and refining process of EAF,control the electrode spray water open of EAF,optimize the flow control in Ar on VD process,the hydrogen content is less than 1.5 × 10-6 in the end of refining process in smelting HIC-resistance and SSCC-resistance pipeline steel refining. |
