摘　　要：在富氧顶吹熔融还原冶炼高磷铁矿的工艺研究中,以共存理论为基础,结合全选主元松弛迭代法,利用VB 6.0计算了CaO-MgO-FeO-Al2O3-SiO2-P2O5渣系中结构单元或离子对的质量作用浓度,并建立了该渣系与碳饱和铁液间硫分配比的热力学模型,由该模型计算的硫分配比与工艺中实测的硫分配比吻合程度较好,说明利用共存理论所建立的脱硫模型能适用在熔融还原高效脱磷熔渣。In the process of research on Huimin high-phosphorus iron smelted by smelting reduction, the mass action concentrations of structural units or ion couples of CaO-MgO-FeO-Al2O3-SiO2-P2O5 slags were calculated by using of VB 6.0 in combination with select the main element relaxation iterative method based on the ion andmolecule coexistence theory, and the desulfurization model of this slags is developed, sulfur distribution ratio calculated from this model had better agreement with that tested in process, which indicates the desulfurization model can he applied in high efficient dephosphorization slags.
