- 論文の詳細を見る
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 present paper is the analysis of experimental data for fully liquid slags in the ‘FeO’–MgO–SiO2, CaO–‘FeO’–MgO–SiO2 and Al2O3–CaO–‘FeO’–MgO–SiO2 systems in equilibrium with metallic iron. Model parameters for the quasi-chemical viscosity model for the system Al2O3–CaO–‘FeO’–MgO–SiO2 are presented. The model has been optimised for the whole composition range at temperatures between 1423 K and 1873 K.
