摘　　要：为实现w[S]≤0.0015%超低硫管线钢批量生产,以实际生产数据为基础,对精炼渣碱度、氧化性以及气体搅拌程度等因素对LF脱S效率的影响进行了分析,提出了相应的工艺优化方案,并进行了工业试验验证。实验结果表明:钢包渣碱度为5.5-7.5;w(FeO+MnO)<0.5%以时,LF具有高效深脱硫效果,w[S]可基本控制在0.0013%以下,具备批量生产条件。In order to realize the batch production of ultra-low sulfur pipeline steel with w[S]≤0.0015%,based on the actual production data,the effects of refining slag basicity,oxidizability and gas stirring degree on LF De-S efficiency were analyzed,and the corresponding process optimization scheme was put forward,which was verified by industrial test.The results show that the basicity of ladle slag is 5.5-7.5.When w(FeO+MnO)<0.5%,LF has high efficiency and deep desulfurization effect,w[S]can be basically controlled below 0.0013%,which is suitable for mass production.
