摘　　要：本文用正交设计方法对用于钢包精炼的ＣａＯ－ＳｉＯ２－Ａｌ２Ｏ３－ＭｇＯ－ＣａＦ２渣系成分进行优化，试验表明影响炉渣泡沫稳定性能的因素依次为碱度，ＣａＦ２，Ａｌ２Ｏ３和ＭｇＯ的含量，最佳的精炼渣组成为：ＣａＯ３９．３％，ＳｉＯ２１９．７％，Ａｌ２Ｏ３２５％，ＭｇＯ６％，ＣａＦ２１０％（Ｂ＝２）The optimum composition of CaOSiO2Al2O3MgOCaF2 system which is widely used in ladle refining is determined by means of orthogonal experiment and theoretical analysis. Factors influencing the stability of foamy slag have a descending order of the basicity, the composition of CaF2, Al2O3 and MgO and the optimum compositon is CaO 39.3%, SiO2 19.7%, Al2O3 25%, MgO 6%, CaF2 10%(B=2).
