| 摘 要： | 针对几种典型转炉渣的成分分析，由FeOn^-(CaO MgO MnO)-(SiO2 P2O5）等活度图回归出氧化铁和氧化钙的活度，以确定其有效浓度，并在此基础上制定了转炉渣替代部分典型脱磷剂的热力学配方模型。该模型在保持脱磷率不变的情况下，根据典型脱磷剂中石灰、烧结矿、萤石的比值，同时考虑萤石对转炉渣液相线的影响，计算出用转炉渣替代部分脱磷剂后的脱磷剂新配方。

| Abstract: | According to the analysis of typical BOF slags,the activities of FeO and CaO in the slags were obtained from the iso activity diagrams of (CaO+MgO+MnO) (SiO 2+ P 2O 5) FeO n system,whereby the effective concentrations of CaO and FeO in BOF slag were determined. Based on these effective concentrations,a mathematical model was developed to calculate the substitution of sinter dust and lime from a typical dephosphorization reagent by BOF slag, keeping the dephosphorization efficience unchanged. Finally, considering both the ratio of lime,sinter and fluorite in typical dephosphorization slag and the effect of fluorite on the liquids of the BOF slag,the adjustment of the fluorite addition was determined, arriving at the complete composition of dephosphorization flux. |
