摘要
将修正的似化学模型应用于估算SiO2-CaO-MnO（1823 K,1773 K）熔渣体系组元MnO的活度。通过非对称近似计算得到该组元活度值aMnO,并与实验数据比较,所获得的平均相对误差和标准偏差分别为：SM＊nO.1823K=±22%,S＊MnO.1823K=±0.1040和SM＊nO.1773K=±41%,SMnO.1773K=±0.1561与采用Pelton键能参数近似计算值基本一致,这表明该模型的估算值在熔渣实验误差范围内（10%~30%）与实验值较吻合。因此,在二元参数近似下,利用该模型估算三元熔渣组元活度是可行的。
The application of modified quasi-chemical model to estimating ternary slag system of SiO2-CaO-MnO（1 823 K,1 773 K） is carried out in this paper.Activity values aMnO of the component MnO in the system are obtained through asymmetry-approximate calculation.The average relative deviation and the standard deviation between the calculation results and experimental data are respectively： S＊ MnO.1 823 K =±22%,S＊MnO.1 823 K=± 0.104 0;S＊MnO.1 773 K=±41%,SMnO.1 773 K=±0.156 1.This result is basically in accordance with the approximate calculation of Pelton＇s bond energy parameters.It is indicated that this model fits better with experimental data within the error permeation（10%~30%） of experimental activity values.Therefore,it is feasible to use the model to predict the activity of the component in ternary slag system under the condition of using approximate binary parameter.
