摘　　要：为了研究CaO-SiO2-Al2O3-MgO四元渣系的脱硫能力,通过KTH模型及Factsage热力学软件计算了CaO-SiO2-Al2O3-MgO的硫容量CS,采用Ohta和Suito经验公式及硫分配比与硫容量之间的关系计算了42CrMoA钢在LF精炼时用CaO-SiO2-Al2O3-MgO渣系脱硫的硫分配比LS,并分析了碱度、CaO/Al2O3、MgO等因素对CS和LS的影响,优化出CS和LS较大时最佳的成分。In order to study deslfurization capacity of CaO-SiO2-Al2O3-MgO,the sulfur capacities of CaOSiO2-Al2O3-MgO were caculated by KTH model and Factsage software. The sulphur distribution radio of Ca O-SiO2-Al2O3-MgO were calculated using empirical formula of Ohta and Suito and relation between CS and LS. Meanwhile,factors such as alkalinity,CaO / Al2O3 and MgO,which influence on CSand LSwere analyzed,at last,the best ingredients was optimized when the CSand LSis bigger.
