摘　　要：利用Factsage软件和KTH模型计算并分析了不同MgO含量时四元渣系CaO-Al2O3-SiO2-MgO的硫容量以及钢液（1600℃）溶解铝质量分数为0．03％时渣钢间硫平衡分配比的影响。得出控制炉渣成分为w（MgO）〈8％，w（CaO）=54％～59％，w（Al2O3）=25％～30％，w（SiO2）=6％～10％时，渣钢间硫平衡分配比能达到500以上，能满足快速冶炼超低硫钢的要求。The effect of different MgO content on the sulfide content of the CaO-Al2O3-SiO2-MgO slag series as well as on the sulfur equilibrium distribution with steel of 0. 03%[Als] and 1 600 ℃ are studied by Factsage software and KTH model. The resuits show the sulfur equilibrium distribution is up to 500 with the slag compositions of MgO〈8%,CaO= 54%-59 %,Al2O3 = 25 %-30 %,8iO2 = 6 %-10 % and as the results the requirements of making super low sulfur steel can be satisfied.
