为了估计复杂炉渣的密度，本文作者将一个基于炉渣热力学的模型扩展到三元和多组分体系。三元及更高级体系的摩尔体积由相应渣系混合的相对积分摩尔体积导出。通过使用先前评估的相关二元子系统的参数预测了更高阶的渣系。计算结果与文献中的摩尔体积的实验数据的比较显示出令人满意的协议的一些系统，在实验的不确定性范围内。该模型提出了一种很有前途的方法来计算渣系的摩尔体积，没有实验数据，使用丰富的热力学数据。该模型还将使生成的密度数据的炉渣含有Al2O3，CaO，FeO，MgO，MnO和SiO2与相应的热力学数据兼容。
In an attempt to estimate the densities of complex slags, a model based on the thermodynamics of slags developed earlier by the present authors is extended to ternary and multi‐component systems in the present work. The molar volumes of ternary and higher order systems were derived from the relative integral molar enthalpies of mixing of the corresponding slags. The higher order of slag systems has been predicted by using the parameters from the related binary sub‐systems, which have been evaluated earlier. Comparisons of calculated results with experimental data on molar volumes available in literature show a satisfying agreement for a number of systems, within the limits of experimental uncertainties. The model presents a promising method to compute the molar volume of slag systems where no experimental data is available using the abundance of thermodynamic data available. The model would also enable the generation of density data for slags containing Al2O3, CaO, FeO, MgO, MnO, and SiO2 compatible with the corresponding thermodynamic data.
