Claims (1)
- 上底吹き機能を備えた転炉を用い、上吹きランスから気体酸素源を供給しつつ、底吹きノズルから不活性ガスを搬送用ガスとしてCaO系媒溶剤の一部または全部を固体酸素源とともに鉄浴中に吹き込んで、溶銑を脱炭精錬して溶鋼を溶製する転炉精錬方法であって、
前記上吹きランスから前記気体酸素源を供給する脱炭精錬中に、前記底吹きノズルから吹き込むCaO系媒溶剤中のCaO質量純分をA(kg)、前記底吹きノズルから吹き込む固体酸素源中の酸素ガス体積換算純分をB(Nm3)としたとき、A/B(kg/Nm3)が2〜70の範囲内となるようにCaO系媒溶剤または固体酸素源の吹き込み量を調整することを特徴とする転炉精錬方法。
