Publication number: 20240076754Abstract: A molten iron refining method having, an auxiliary material, and an oxidizing gas supplied through a top-blowing lance, to a cold iron source and molten pig iron that are contained/fed in a converter-type vessel, and molten iron is subjected to a refining process. A pre-charged cold iron source is charged into the converter-type vessel at an amount not larger than 0.15 times. A furnace-top-added cold iron source that's part or all of the cold iron source and added from a furnace top is fed during the refining process. A burner at a leading end of the top-blowing lance that spray holes through which a fuel and a combustion-supporting gas are ejected. During the refining process, a powdery auxiliary material processed into powder that's part of the auxiliary material is blown in, to pass through a flame formed by the burner.Type: ApplicationFiled: December 21, 2021Publication date: March 7, 2024Applicant: JFE STEEL CORPORATIONInventors: Futoshi OGASAWARA, Hidemitsu NEGISHI, Kenji NAKASE, Shota AMANO, Yumi MURAKAMI, Rei YOKOMORI, Yudai HATTORI, Ryo KAWABATA, Naoki KIKUCHI
