Depending on composition and temperature, pyrometallurgical slags are not always completely molten, but can contain significant amounts of solid phases. These solid phases may be slag forming agents (e.g. lime or doloma) or other added materials that are not yet molten and dissolved into the molten slag phase. Additionally, slag heterogeneity may also be a result of composition and conditions in which some solid phases are thermodynamically stable with the molten phase. The purpose of this study was to study slag heterogeneity in the Argon-Oxygen-Decarburisation (AOD) process while producing austenitic stainless steels. Thermodynamic calculations were used to compute the amounts and compositions of molten and solid phases using slag compositions typical for different stages of the AOD process as initial values. In addition to slag composition, the effect of temperature was also studied.
