ժҪ Modified quasi-regular solution model has been got based on the sub-regular solution model and quasi-regular solution model in this article. The mixed energy parameter can be denoted a function of concentration and temperature. The three parameters of this model are fitted by the computer-assisted analysis based on the experiment data of activity at two different temperatures. Seven binary molten slag systems in the whole concentration are calculated with the application of the model and the average relative error is within 10%. That shows that the calculated result is agreement with the experiment data. Ten binary slag systems presenting saturation concentration are also calculated, but the average relative error is bigger. So the calculated result is not good agreement with the experiment data. But the calculated result is superior to regular solution model, sub-regular solution model and quasi-regular solution model.
