摘　　要：通过热力学分析方法,结合相关热力学数据,从去磷保铬保碳的角度,对铬铁合金氧化脱磷的反应过程进行了分析计算。计算结果表明,BaO基高碱性渣更适合于铬铁合金的氧化脱磷,另外,加入适量的Cr2O3,可以更好的控制体系中的氧势值,提高初始碳含量、降低初始温度,有利于铬铁合金氧化脱磷,从而为铬铁合金的冶炼提供理论依据。By means of thermodynamic analysis, based on correlated thermodynamic data, the reaction process of oxidizing dephosphorization of ferrochromium alloy was studied from the point of dephosphorizationand chromium conservation. It is found that highly basic BaO based slags is more suitable for oxidizing dephosphorization of ferrochromium alloy. In addition, oxygen potential is controlled better by the addition of certain amount of Cr2O3. The initial carbon concentration should be increased and the initial temperature should be reduced to protect the oxidizing de- phosphorization of ferrochromium alloy. It can provide theoretical basis for the smelting of ferrochromium alloy.
