Title:
粒状金属鉄製造用酸化チタン含有塊成物
Document Type and Number:
Japanese Patent JP5384175
Kind Code:
B2
Abstract:
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) [Al2O3]/[SiO2]=0.3 to 1.0 (2) [TiO2]/([CaO]+[SiO2]+[MgO]+[Al2O3])<0.45 (3). Each of [CaO], [SiO2], [Al2O3], [TiO2] and [MgO] represents content (mass % on dry basis) of each component in the agglomerate.
