<p>Provided is an agglomerate for manufacturing granular metallic iron, said agglomerate containing titanium oxide and being useful in obtaining a high yield of high-grade granular metallic iron in a size that is suitable for handling, by heating at a comparatively low-temperature and using a ferrous material containing titanium oxide and other gangue components. The agglomerate comprises: a ferrous material including titanium oxide in an amount equivalent to at least 5 mass% and less than 10 mass% of TiO; and a carbonaceous reducing agent. The chemical composition of the agglomerate fulfills the conditions given in formulas (1) through (3) below. [CaO]/[SiO] = 0.6 to 1.2 (1) [AlO]/[SiO] = 0.3 to 1.0 (2) [TiO]/([CaO]+[SiO]+[MgO]+[AlO]) < 0.45 (3) Here, the symbols [CaO], [SiO], [AlO], [TiO], and [MgO] represent the amounts (mass% on dry basis) of each respective component included in the agglomerate.</p> |
