Development of a quasi-chemical viscosity model for fully liquid slags in the Al2O3-CaO-'FeO'-MgO-SiO2 system. The experimental data for the 'FeO'-MgO-SiO2 ' CaO-'FeO'-MgO-SiO2 and Al2O3-CaO-'FeO'-MgO-SiO2 systems at iron saturation
TL;DR: In this paper, a structural-based quasi-chemical viscosity model has been developed for the Al2O3-CaO-FeO-MgO-SiO2 system in equilibrium with metallic iron.
Journal ArticleDOI
Model Development of Slag Foaming
TL;DR: In this article, a general model of foaming has been developed which relates the structure of a foam stabilised by viscoelastic forces to the bubble rupturing processes, and it has been shown that, in the region of linearity between the foam height and gas flux, the residence time of gas in the foam (Σ) is solely a function of the bubble diameter (d), the liquid phase density (ρ) and viscosity (μ), and the effective elasticity (Eeff) resulting from the dynamic adsorption of surface active species.
Journal ArticleDOI
Phase Equilibria in Ferrous Calcium Silicate Slags: Part III. Copper-Saturated Slag at 1250 °C and 1300 °C at an Oxygen Partial Pressure of 10−6 atm
TL;DR: In this paper, the phase equilibria of ferrous calcium silicate slags at copper saturation were investigated using the equilibration/quenching/electron probe X-ray microanalysis (EPMA).
Journal ArticleDOI
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
TL;DR: In this article, a structural-based quasi-chemical viscosity model was developed for the Al2O3 CaO-'FeO'-MgO-SiO2 system, which links the slag visco-ity 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.
Journal ArticleDOI
Phase Equilibria of “Cu2O”-“FeO”-CaO-MgO-Al2O3 Slags at PO2 of 10-8.5 atm in Equilibrium with Metallic Copper for a Copper Slag Cleaning Production
TL;DR: In this paper, the phase equilibria of the multicomponent slag system at the oxygen partial pressures used in the copper smelting, converting, and slag-cleaning processes were analyzed.
