Abstract

The cold-bonded carbon composite agglomerates have a carbon content (T. C) in a range of 18 to 25% by mass, and a ratio CaO/SiO2 between a CaO content (% by mass) and a SiO2 content (% by mass) in a range of 1.0 to 2.0. The method for manufacturing cold-bonded carbon composite agglomerates includes: forming a molded body by mixing and kneading iron-containing raw materials, carbon-containing raw materials, and a binder and molding a kneaded substance to obtain the molded body; and obtaining cold-bonded carbon composite agglomerates by subsequently curing the molded body, wherein either one or both of blending conditions of an iron ore brand and a binder blending amount are adjusted in the forming of the molded body such that a carbon content (T. C) becomes in a range of 18 to 25% by mass and a ratio of CaO/SiO2 between a CaO content (% by mass) and a SiO2 content (% by mass) as gangue mineral constituents becomes in a range of 1.0 to 2.0 in the cold-bonded carbon composite agglomerates.
