中文摘要：
基于炉渣离子-分子共存理论（IMCT）建立了CaO-MgO-FeO-Fe2O3-SiO2渣系的磷分配比预报模型,即IMCT-LP模型.比较了该渣系在1823-1873 K时实测的磷分配比、IMCT-LP模型预报的磷分配比及其他6种磷分配比模型的计算结果.与实测值和其他磷分配比模型预报结果相比,由IMCT-LP模型预报的CaO-MgO-FeO-Fe2O3-SiO2渣系的磷分配比更精确.本文建立的IMCT-LP模型不仅可计算该渣系的磷分配比,而且可计算该渣系中碱性离子对（Ca^2＋＋O^2-）、（Mg^2＋＋O^2-）和（Fe^2＋＋O^2-）各自的磷分配比.
英文摘要：
A thermodynamic model of the phosphorus distribution ratio（ LP） of CaO-MgO-FeO-Fe2O3-SiO2 steelmaking slags was developed based on the ion and molecule coexistence theory（ IMCT） of slags and verified by experimental data. The predicted phosphorus distribution ratio of CaO-MgO-FeO-Fe2O3-SiO2 steelmaking slags in a temperature range of 1823 to 1873 K by the developed IMCT-LPmodel is more accurate than the measured as well as the predicted phosphorus distribution by other phosphorus distribution models. The developed IMCT-LPmodel can calculate not only the total phosphorus distribution of the slags but also the respective phosphorus distribution of ion pairs（ Ca^2 ＋＋ O^2-）,（ Mg^2 ＋＋ O^2-）,and（ Fe^2 ＋＋ O^2-） in the slags.
