Abstract

Decarburization is divided into stage I (high carbon region) and stage II (low carbon region). The critical carbon concentration at transfer from stage I to stage II decreases when the oxygen supply rate is restrained or when bath stirring intensity is increased. The total oxygen content in the bath during blowing becomes gradually larger than the dissolved oxygen content as (%C) decreases and suspended oxides of composition similar to FeO multiplied by (times) Cr//2O//3 are dispersed into the bath.
