摘要： A method for producing a titanium containing slag, which comprises heating a raw material mixture containing a titanium oxide, an iron oxide and a carbonaceous reducing agent or another raw material mixture further containing a calcium oxide source in addition to the above in a reducing furnace to reduce the iron oxide in the mixture to a reduced iron, supplying the product to a heating type melting furnace, heating the product in the melting furnace to melt said reduced iron and separate it from a slag containing a titanium oxide, and discharge the resultant titanium oxide containing slag to the outside of the furnace for recovery. The method can be used for producing a titanium oxide containing slag from a material containing a titanium oxide and an iron oxide with good efficiency, while suppressing the reduction of titanium dioxide and minimizing electric power consumption.

摘要： A process for producing molten iron wherein a formed material containing iron oxide and a carbonaceous reducing agent is used as a raw material, and a rotary hearth furnace and a melting furnace are connected, characterized in that said formed material is first charged into a heating and reducing furnace, to enhance a metallization rate to 60 % or more prior to the feed to the melting furnace, and the secondary burning rate of a CO gas in said melting furnace is controlled to 40 % or less. The process allows the suppression of the loss by melting of refractories of the rotary hearth furnace and the melting furnace, in combination with the production of a molten iron having an enhanced purity of iron with good productivity.

摘要： An object of this invention is to provide a titanium-containing agglomerate for producing granular metallic iron. The agglomerate is useful for obtaining a high yield of high-quality granular metallic iron in a size that is suitable for handling by using an iron source containing titanium oxide and other gangue components and heating at a relatively low temperature. The agglomerate contains: an iron source including titanium oxide of at least 5 mass % but less than 10 mass % in terms of TiO2-equivalent content; and a carbonaceous reductant, wherein the agglomerate has a chemical composition satisfying a condition set forth in formulas (1) to (3) below, [CaO]/[SiO2] = 0.6 to 1.2 (1) [A1 2O3]/[SiO2] = 0.3 to 1.0 (2) [TiO2]/([CaO] + [SiO2] + [MgO] + [A1 2O3])
