摘要：
Provided is a carbon composite briquette which is used as the raw material of a movable hearth furnace for producing reduced iron having a sufficient carbon content and a higher crushing strength, and also provided is a method for producing reduced iron using the carbon composite briquette. The carbon composite briquette for producing reduced iron has a total SiO2+Al2O3+CaO+MgO content that is between 7 and 15 mass %; an MgO content that is between 0.1 and 6 mass %; an Al2O3/SiO2 mass ratio that is between 0.34 and 0.52; a CaO/SiO2 mass ratio that is between 0.25 and 2.0; and a C content such that between 1 and 9 mass % of C is retained in the resulting reduced iron.
