The kinetic behavior of aluminum oxidation in molten iron by CaO-SiO2-Al2O3, CaO-Al2O3-FeO, CaO-Al2O3-MnO and CaO-SiO2-Al2O3-FeO-MnO slags was investigated at 1 600°C under an argon atmosphere. The oxidation rate of aluminum by SiO2 is slower than those by FeO and MnO in CaO-Al2O3 slag. No difference in the oxidation rate could be observed between slag containing FeO or MnO. More insoluble alumina inclusions were observed in the metal for slag containing FeO or MnO than in that containing SiO2.
