Inclusions — Modeling Studies
This work aims to understand the kinetics of inclusion composition changes during ladle refining using kinetic models. A FactSage-based model was developed to predict transient composition of inclusions. The model was applied to predict transient inclusion composition after aluminum deoxidation in a setup simulating a ladle furnace. Induction furnace experiments were conducted to find model parameters related to steel-slag reaction, inclusion flotation and MgO-crucible dissolution. Future work is expected to help in developing a better understanding of modification of solid alumina inclusions into liquid calcium aluminate inclusions, through steel-slag-inclusion reactions.
