Abstract
Reoxidation of aluminum in liquid iron containing 00.6 mass%Te with the CaO-Al2O3-FetO (≤3 mass%) slags was studied at 1873 K in an Al2O3 or CaO crucible. After reoxidation for 5 and 60 min, the contents of acid-insoluble aluminum, total oxygen and FetO were obtained as a function of total aluminum content. The relations between FetO and Al contents were observed to be in equilibrium in the experiments except those for the CaO-Al2O3 slags in an Al2O3 crucible at 5 min. The oxygen content in liquid iron for a given Al level was found to be higher than the equilibrium value in the rapid cooling experiments except those for the CaO-Al2O3 crucible at 60 min with Te addition.
