The effect of desulfurizing,purifying and modifying inclusion at ladle furnace for pipeline steel was investigated.The results show the average desulfurization percentage was 55%,the removal percentage of total oxygen and micro inclusion were 43.3% and 44.4% respectively.The effects of desulfurizing and purifying were satisfactory.After the addition of calcium silicon alloy,the cluster alumina were modified into spherical calcium aluminate with low melting point,at the same time,the liner MnS inclusion were eliminated,and so improve the resistance against hydrogen induced cracking(HIC).When the addition of calcium-silicon wire was 0.7 kg/t,the inclusion modification was insufficient,so the addition should be increased appropriately.
