| Abstract: | Through hot metal pretreatment,steel tapping by slag skimming after top-bottom combined blowing in the converter,adding slag modifier and deoxidizer,purifying the liquid steel by RH vacuum treatment,LF treatment,desulphurizing with high-efficient 60%CaO-30%Al2O3-8%SiO2 slag and calcium treatment,the sulphur content in the steel was controlled to 5×10-6 blow.The Ca wire of feeding was only 0.3 kg/t.Then the crack rate of the pipeline steel was reduced from 15% to 3% about. |
