METHOD OF JUDGING THICKNESS OF REFRACTORY LINING LAYER OF PIG IRON LADLE CAR FURNACE BODY例文帳に追加

混銑車炉体の耐火物ライニング層厚みの判定方法 - 特許庁

To inhibit a lined refractory from being damaged in a process of previously charging a cold iron source such as scrap iron and a base metal into a pig iron ladle car before it receives pig iron, receiving the pig iron with the pig iron ladle car, and melting the cold iron source to be used as an iron material, by reducing an impulsive force to the lined refractory when the cold iron source is charged.例文帳に追加

受銑前に予め鉄スクラップ及び地金などの冷鉄源を混銑車に装入し、その後、混銑車で受銑して冷鉄源を溶解させ、冷鉄源を鉄原料として利用するに当たり、冷鉄源装入時の内張り耐火物への衝撃力を減少させ、内張り耐火物の損傷を抑制する。 - 特許庁

The method includes, using a top and bottom blown converter, introducing ladle slag into the converter as a slag former and spraying top-blown oxygen as well as a CaO source powder onto the molten pig iron in the converter, thereby dephosphorizing the molten pig iron.例文帳に追加

上底吹き型の転炉を用い、スラグ生成剤として取鍋スラグを転炉内に投入し、上吹き酸素とともに粉状CaO源を転炉内の溶銑へ吹き付けて溶銑を脱燐処理する方法である。 - 特許庁

This desulfurization method comprises recovering the desulfurization slag S produced by desulfurization, storing it in a slag-recovering pot 3, tilting the slag-recovering pot 3 toward a hot metal ladle 4 which stores molten pig iron to be desulfurized, charging the high-temperature desulfurization slag S1 into the hot metal ladle, then stirring the molten pig iron, and then charging a new lime-based desulfurizing agent 9.例文帳に追加

脱硫により発生した脱硫スラグＳをスラグ回収鍋３に回収し、そのスラグ回収鍋３を、脱硫対象の溶銑を収容した溶銑鍋４に向けて傾動して高温の脱硫スラグＳ１を投入した後に、攪拌し、その後新たな石灰系脱硫剤９を投入して脱硫を行う。 - 特許庁

To inhibit a base metal from adhering to a hot-metal ladle for desulfurizing a charged molten pig iron while stirring it with a stirring blade, and to the stirring blade.例文帳に追加

溶銑鍋に溶銑を入れて撹拌羽根で撹拌して脱硫処理する脱硫用溶銑鍋の溶銑鍋や撹拌羽根に地金が付着するのを抑制することにある。 - 特許庁

To provide a method for smelting a low nitrogen steel with which, in a ladle treatment for raising a temperature by utilizing the oxidizing exothermic reaction of Al, the nitrogen-absorption reaction of molten pig iron is restrained and concentration of the nitrogen can be kept to a low level.例文帳に追加

Ａｌの酸化発熱反応を利用して昇熱を行う取鍋処理において、溶鋼の吸窒反応を抑制し、窒素濃度を低位に維持できる低窒素鋼の溶製方法を提供する。 - 特許庁

To provide a method for desiliconizing or dephosphorizing a molten pig iron with the use of a container having a small free board such as a hot-metal ladle and a torpedo car, while inhibiting an outburst of slag, shortening the treatment period of time, and enhancing the productivity even without arranging a cylindrical body for securing the free board.例文帳に追加

溶銑鍋や混銑車などのフリーボードの小さい容器を用いて溶銑の脱珪処理或いは脱燐処理を行うにあたり、フリーボードを確保するための筒状体などを配置しなくても、スラグの噴出を抑制して処理時間を短縮し、生産性を向上させる。 - 特許庁
