Abstract

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 Si0.5O, Me2/nn+O and Me1/nn+Si0.25O 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.
