【摘要】 基于山东莱钢现阶段LF精炼渣系脱硫效果差等问题,结合精炼渣脱硫机理进行实验研究。通过拟出10种精炼渣配方进行炉渣性能及钢中脱硫分析。研究发现,当精炼渣成分范围为:CaO45～50%,SiO₂ 18～21%,Al₂O₃ 17～21%,MgO 9～13%时脱硫效果较好,满足精炼渣性能及钢中夹杂物要求。工业试验初步取得良好效果,为LF精炼渣系深脱硫提供依据。更多还原

【Abstract】 Based on the problem about LF refining slag the poor desulfurization at Shandong Laiwu steel plant,the experiments were made with the mechanism of refining slag desulfurization.The refining slag performance and the[S]content in the steel about the 10 kinds of prepared formula were analyzed.The study found that when the refining slag was at the composition range:CaO 45～50%,SiO₂ 18～21%,Al₂O₃ 17～21%,MgO 9～13%,the desulfurization effect was better performance and to meet the refining slag inclusions in steel requirements.The practice experiments obtained good results in preliminary tests.It would provide the basis for deep desulfurization for the LF refining slag.更多还原
