Estimation of Various Properties of CaO–“FeO”–SiO2 System at 1,673 K by Mass Triangle Model

Abstract

AbstractIn consideration of great need for the physicochemical properties of slag systems in metallurgical process estimation, this work examined the possibility of predicting multi-properties by one model. The mass triangle model was applied to evaluate the density, viscosity, surface tension and sulfide capacity of CaO–“FeO”–SiO2 system at 1,673 K. Good agreements were achieved between calculated data and experimental data in the various properties. Meanwhile, the calculated contour lines successfully predicted the properties of slag within the limited solubility area. The new model thus is competitive and flexible when an integrated knowledge of a certain system is necessary.
