Induction furnace experiments were conducted to find model parameters related to steelslag reaction, inclusion flotation and MgOcrucible dissolution. Future work is expected to help in developing a better understanding of modification of solid alumina inclusions into liquid calcium aluminate inclusions, through steelslaginclusion reactions.
