combined blowing converterとは 意味・読み方・使い方

GAS BLOWING LANCE AND OPERATION OF TOP-BOTTOM COMBINED CONVERTER USING THIS LANCE例文帳に追加

ガス吹きランスおよびそれを用いた上底吹き転炉の操業方法 - 特許庁

To provide a preliminarily deoxidizing method which keeps an oxygen content in a molten steel low, without adding such a deoxidizer as to form an oxide-based inclusion, in a top and bottom combined blown converter in which blowing has been finished.例文帳に追加

上底吹き転炉での吹錬終了後に、転炉内で酸化物系介在物を生成させる脱酸剤を添加することなしに、溶鋼中の酸素を低く抑えることのできる予備脱酸方法を提供する。 - 特許庁

In the method for performing the desiliconizing and dephosphorizing treatment by charging the molten iron into a top-bottom combined blown converter system pretreating furnace and top-blowing oxygen while adding Cab, the dephosphorizing reaction is improved by adding the carbonaceous material from the upper part to inject the added carbonaceous material and the equivalent quantity of the oxygen.例文帳に追加

上底吹き転炉方式の予備処理炉に溶銑を装入し、ＣａＯを添加しつつ、酸素を上吹きして脱珪・脱りん処理を実施する方法において、 炭材を上方から添加して、添加した炭材と当量分の酸素を吹込むことで脱りん反応を向上させる溶銑の脱りん方法。 - 特許庁

The method for preliminarily deoxidizing the molten steel comprises changing a stirring gas to be blown from a furnace bottom, from carbon dioxide gas to a gas mainly containing hydrocarbon, and rinsing the molten steel with the gas, simultaneously with stopping the top blowing of oxygen, in a method for refining dephosphorized molten pig iron in the top and bottom combined blown converter.例文帳に追加

脱りんした溶銑を上底吹き転炉で精錬する方法において、酸素の上吹きを停止するとともに、炉底から吹き込む撹拌ガスを炭化水素を主成分とするガスに変えてリンスすることを特徴とする溶鋼の予備脱酸方法。 - 特許庁
