摘　　要：为进一步优化炉渣成分,对莱钢现场渣系调研分析并在实验室开展渣系优化实验。结果表明,随着碱度的提高,脱硫效果明显提高,高碱度渣系对降低全氧含量有利;渣指数相对高的区域全氧含量则相对较低;综合实验室研究和其它研究渣系结果,确立莱钢LF冶炼铝镇静钢的目标渣系为CaO 53%,SiO2 7%,Al2O3 30%,MgO 8%,CaF2〈2%。硅镇静钢的目标渣系为CaO 53%,SiO2 30%,Al2O3 10%,MgO 6%,CaF2〈2%。In nrder to fu system of Laiwu carried out. The proved obviously the total oxygen laboratory study ther optimize the compositions of slag, the study s carried out, and the corresponding optimization showed that, with the increase gh basicity slag system was adv was lower at the area with high of alkalinity, the and analysis on the field slag experiment for slag system was desulfurization effect was im- antageous to reduce the total content of oxygen ; er slag indexes; according to the comprehensive anti other slag system research results, the target slag system for the smehing f Al-killed steels was established： CaO 53% ,SiO2 7% ,Al2 O3 30% , MgO 8% ,CaF2 〈 2% , and the target slag sys- tem for the smelting of Si-killed steels was CaO 53% ,SiO2 30% ,Al2O3 10% , MgO 6% ,CaF2 〈2%.
