Method of producing reduced iron agglomerates |
摘要 |
A method of producing reduced iron agglomerates capable of preventing oxidation in the surface layer of the agglomerates and obtaining reduced iron agglomerates having a high degree of metallization, by blowing a methane or methane-containing gas to the reduced iron oxide agglomerates incorporated with carbonaceous material at a surface temperature of 1150° C. or higher during movement in a moving hearth heating type furnace at the end of reduction as the final stage of the stagnation period of the agglomerates in the heating furnace.
