【Abstract】 A molten slag structural model based on chemical statistical thermodynandcshas been introduced. The model describes the Lepresentation of multicomponent oxide liquids in terms of cell composed of an oxygen anion surrounded by two cations, and made use of only binary parameters (2 to 3 per binary system). Calculation provides the thermodynamic proper ties of multicomponent oxide mixture. Using this model considering the equilibrium of reaction of steel and inclusions, and the activities of alloy elements in steel are calculated by Wagner’s inlteraction coefficients, a precedure is developed to compute the molten slag properties and the compositions of oxide inclusions. The results are in good agreement with industrial product steel and experiments. This has initiated a new application in improvmelit of Pyrometallurgy process and research aspects of inclusion engineering.更多还原
