冶金熔渣热力学性质的SReS模型

A SUBREGULAR SOLUTION MODEL FOR METALLURGICAL SLAGS

通过对正规溶液模型的修正，并引入ＣＡＬＰＨＡＤ技术，构成了物理意义明确和数学形式简洁的冶金熔渣亚正规（ＳＲｅＳ）模型，这实际上是ＳＥＬＦ－ＳＲｅＭ模型的一种发展．应用ＳＲｅＳ模型对若干硅酸盐、两性化合物以及简单离子二元熔体的热力学性质进行了计算。

Based upon modification of the regular solution theory, a subregular solution model, SReS, has been proposed for the analysis of the thermodynamic properties of metallurgical slags. With its explicit physical background and simple mathematical formalism, the SReS model can be coupled with the CALPHAD techniques to optimize simultaneously all available information including activities, enthalpies and phase diagram data etc. Examples of application of the SReS model to binary silicate melts, amphoteric oxide melts and simple ionic melts showed that its calculation results are more reliable than those of regular solution model.
