- Аннотация: An original method is developed for predicting the temperature and concentration dependences of surface tension for molten slag of the CaO–Al2O3–CaF2 system and its subsystem components. It is based on approximating component activity within the volume and at the surface of a melt within the scope of associated solution theory. Free model parameters are established on the basis of available experimental data for thermodynamic, structure-sensitive physicochemical, including surface tension, molten slag properties. The method developed makes it possible to predict the temperature and concentration dependences of surface tension for metallurgical slags containing apart from oxides, compounds of a different nature with accuracy no worse than experimental, and it may be extended to melts of any complexity and component content. Prospects for its use are demonstrated for selecting a slag regime in various metallurgical processes.
