【摘要】 运用前人的实验数据 ,以根据钢中的氧计算的氧化铁的活度系数和三元相图查出的氧化铁的活度系数为标准 ,把各种模型计算出的氧化铁的活度系数跟它进行方差计算 ,结果表明 ,在整个碱度范围内 ,可以用正规溶液模型、法国钢铁研究院模型、分子理论模型来计算氧化铁的活度系数 ,而离子理论模型只在高碱度范围内比较适用更多还原

【Abstract】 The variances between standard r(FeO)calculated with metal oxygen or ternary diagram and r(FeO)calculated with all kinds of model were calculated by use of predecessors’ experimental data.The results show that the regular solution model and molecular theoretical model and the Gaye Model can be used to calculate activity coefficient of FeO in all range of basicity and the ionic theoretical modle can be used in high range of basicity.更多还原
