摘　　要：采用FactsageTM软件对以B2O3、K2O、MnO2、TiO2代替CaF2助熔的4种高磷铁水预处理脱磷渣系在1 623K时的相图进行计算,发现相图中的多数区域都有液态渣出现。根据计算相图制定脱磷实验的配渣方案,实验过程中观察到的化渣情况与计算相图提供的信息基本一致。FactsageTM was employed to calculate the phase diagram of four kinds of slag systems for high phosphorus hot metal dephosphorization pretreatment at the temperature of 1 623 K,with B2O3,K2O,MnO2 and TiO2 in replacement of CaF2 for fluxing.It was found that there appeared liquid slags in most regions in the phase diagrams.Based on the computed phase diagrams,slag scenarios of dephosphorization experiments were determined.And the slagging in the tests basically agreed with the information presented by the computed phase diagrams. ： dephosphorization slag;high phosphorus hot metal;dephosphorization pretreatment;phase diagram computation;FactsageTM software
