To provide a method for producing ferro coke having high cold strength as strength after carbonization and post-reaction strength after reaction with CO2 gas by carbonizing a molded material consisting of an iron oxide-containing material and a carbon-containing material.
The molded material 10, obtained by mixing the iron-containing material and the carbon-containing material and molding the mixture, is carbonized by heating for producing the ferro coke 12. In this process, a part of the iron-containing material and a part of the carbon-containing material are mixed to produce pseudo particles 6 having iron content concentration higher than that of a mixture 4 of the residue of the iron-containing material and the residue of the carbon-containing material, and the pseudo particles 6 are mixed with the mixture 4 to produce the molded material 10. Preferably, the iron content concentration of the pseudo particles 6 is higher than that of the mixture 4 by 5 mass% or more, a maximum particle diameter is 10 mm or less, and a ratio of the pseudo particles 6 in the molded material 10 is 5-50 mass%.
