Abstract

The cold-bonded carbon composite agglomerates for blast furnaces have a carbon content (T. C) in a range of 18 to 25% by mass, and a porosity in a range of 20 to 30%. The method for manufacturing cold-bonded carbon composite agglomerates for blast furnaces 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 a molded body; and obtaining cold-bonded carbon composite agglomerates by subsequently curing the molded body, wherein in the forming of the molded body, one or more blending conditions selected from a group consisting of a water content in the raw materials, a particle size of the raw materials, an amount of fine cokes, a blending amount of ores having a high combined water content, and a binder blending amount are adjusted such that a carbon content (T. C) becomes in a range of 18 to 25% by mass and a porosity becomes in a range of 20 to 30% in the cold-bonded carbon composite agglomerates.
