摘　　要：修正后的Ｂｅｌｌ碱度公式能更准确地代表复杂熔渣的行为；ＭｇＯ代替ＣａＯ稍降低渣相的脱硫能力。计算表明适当的渣相成分使硫在渣一钢液间的平衡分配率可达到１０００。Modified Bell’s basicity equation can represent the slag’s reactivity more appropriately,the replacement of CaO by MgO slightly decreases the ability of desulphurization of slags. Calculation results show that optimal compositions of slags can lead sulphur equilibrium distribution ratio up to 1000.
