Development of a Quasi-chemical Viscosity Model for Fully Liquid Slags in the Al₂O₃–CaO–‘FeO’–MgO–SiO₂ System. Part 2. A Review of the Experimental Data and the Model Predictions for the Al₂O₃–CaO–MgO, CaO–MgO–SiO₂ and Al₂O₃–MgO–SiO₂ Systems

A structurally-based quasi-chemical viscosity model has been developed for the Al₂O₃–CaO–‘FeO’–MgO–SiO₂ system. The model links the slag viscosity to the internal structure of melts through the concentrations of various anion/cation Si_0.5O, Me_2/nⁿ⁺O and Me_1/nⁿ⁺Si_0.25O viscous flow structural units. The concentrations of structural units are derived from the quasi-chemical thermodynamic model.
The focus of the work described in the present paper is the analysis of experimental data and the viscosity models for fully liquid slags in the Al₂O₃–CaO–MgO, Al₂O₃–MgO–SiO₂ and CaO–MgO–SiO₂ systems.
