<p>A method for producing reduced iron comprises agglomerating a raw material mixture containing a carbonaceous reducing agent and an iron oxide-containing material into small agglomerates, heating the agglomerate within a heat reduction furnace, thereby solid reducing the iron oxide in the agglomerate to produce solid reduced iron, or further heating the solid reduced iron, melting the metallic iron produced by the reduction, and coagulating the molten metallic iron while separating the slag component contained in the small agglomerates to provide granular metallic iron, which is characterized by using an agglomerate having a particle size of 10 mm or less or 3-7 mm, preferably less than 6 mm, more preferably 3 mm or more and less than 6 mm as the small agglomerates.</p> |
