Abstract
The oxidation behavior of silicon, phosphorus and niobium in carbon-saturated iron melts have been studied at 1300 degree C using soda (Na//2CO//3, Na//2CO//3-Fe//2O//3) and lime flux (CaO-CaF//2-Fe//2O//3). Phosphorus and niobium were oxidized after the retardation of initial oxidation when flux was added in installments. The reversion of phosphorus and niobium occurred along with the desiliconization reaction after the end of flux addition. The effect of Fe//2O//3 addition was significant in experiments using lump and installment additions. Removal of silicon and niobium was observed in the addition of Fe//2O//3 by installments, while no dephosphorization took place. Removal of niobium was possible without oxidation of manganese if silicon was oxidized to a lower value.
