摘　　要：根据熔渣结构的分子离子共存理论,建立了SiO2-Al2O3-CaO-MgO-FeO-MnO六元渣系的活度计算模型。计算得到了LF精炼渣中FeO的活度值,并分析了炉渣成分Al2O3、FeO以及碱度w(CaO)/w(SiO2)对FeO活度的影响,为帘线钢精炼变渣过程中控制回硫提供指导。An activity calculation model for SiO2-Al2 O3-CaO-MgO-FeO-MnO slag system has been established according to the molecule-ion coexistence theory.From the model,the activity of FeO in the refining slag can be calculated,and the effects of MgO,FeO and basicity w（CaO）/w（SiO2 ）in slag composition on the activity of components related to FeO have been analyzed in this paper,which can provide reference for steelmakers to study the control of resulfurization at changing slag’s process of LF refining to blow tire cord steel.
