oxygen furnace steelとは 意味・読み方・使い方

After molten iron or molten steel is tapped from a melting vessel furnace 1, oxygen-containing gas is injected from a top-blow lance 7 while the slag 9 is retained in the furnace, and the metal 5 adhered to and deposited on the nose part is removed.例文帳に追加

This denitrifying method comprises the steps of: smelting the molten steel in the electric furnace while using scrap iron as a main iron source; tapping the molten steel into another smelting container and holding it therein; charging CaO onto the bath surface of the molten steel without carburization; then adding an Al-containing material; and supplying an oxygen-containing gas to the molten steel.例文帳に追加

電気炉で鉄スクラップを主鉄源として溶鋼を溶製し、別の精錬容器に出鋼，保持した後、該溶鋼の浴面上に、加炭することなくＣａＯを投入してから、Ａｌ含有物資を添加し、当該溶鋼に酸素含有ガスを供給する。 - 特許庁

To refine molten iron or molten steel and simultaneously, efficiently melt the metal stuck onto the inner wall of a converter-type refining furnace, when the molten iron or the molten steel is refined by supplying oxygen from a top-blowing lance.例文帳に追加

上吹きランスから酸素を供給して溶銑または溶鋼を精錬するに当たり、溶銑または溶鋼の精錬と同時に、転炉型精錬炉の内壁に付着した地金を効率良く溶解する。 - 特許庁

To perform the heat-up without damaging the cleanliness in molten steel and also, without increasing carbon content even in the case of restraining the carbon concentration to low, such as an extra-low carbon steel, when the molten steel during treating in a vacuum refining furnace, is heated up by burning Al with oxygen.例文帳に追加

真空精錬炉で処理中の溶鋼を酸素でＡｌを燃焼させて加熱・昇温する際に、溶鋼の清浄性を損なうことなく、且つ、極低炭素鋼のような炭素濃度が低く抑えられた鋼も炭素含有量を増加させることなく加熱・昇温する。 - 特許庁

When an extra-low Ti molten steel is produced by using molten iron tapped from a blast furnace, Ti-reducing treatment is performed by blowing oxygen with a converter type vessel, and thereafter, once the molten iron tapping and slag removal are performed, and decarburizing treatment is performed with the same converter or an exclusive decarburizing furnace.例文帳に追加
