摘要： 采用二次正交回归实验设计方法在中频感应炉内进行碱度R(CaO/SiO₂)2～7的CaO-SiO₂-MgO- Al₂O₃精炼渣系的脱硫实验,建立渣系组分与钢-渣硫分配比Ls关系的数学模型,实验渣碱度、渣指数MI (R:Al₂O₃)、CaF₂、MgO和FeO含量对硫分配比Ls的影响。结果表明,渣碱度R 3.5～5.0、渣指数MI 0.25～0.40时脱硫效果较好;精炼渣最佳组分为(%):9CaF₂、8MgO、13Al₂O₃、<0.5FeO,R值=4。

Abstract: The test of desulphurizing by CaO-SiO₂ -MgO-Al₂0₃ refining slag with basicity R (CaO/SiO₂) 2-7 in a medium frequency induction furnace has been carried out by quadratic orthogonal regression test scheme to establish the mathematical model of relation between ingredient of slag and steel-slag sulfur partition ratio Lfi and examine the effect of slag basicity, slag index MI (R ： Al₂0₃) , content of CaF₂, MgO and FeO on sulfur partition ratio Ls. Results showed that the desulphurizing efficiency of slag with basicity R 3.5 ~5. 0 and slag index MI 0. 25 ~0.40 was better； and the optimum ingredient of refining slag was 9% CaF₂, 8% MgO, 13%Al₂O₃, <0. 5% FeO with R =4.
