摘要： Disclosed is a carbon-material-containing iron oxide briquette composition that, when obtaining direct reduced iron by heating in a moving hearth reduction furnace, does not turn into powder in the furnace leading to an accumulation of powder, and reliably prevents the obtained direct reduced iron from turning into powder during conveyance, decreasing yield. Further disclosed are a method for producing same, and a method for producing direct reduced iron using same. The carbon-material-containing iron oxide briquette composition is characterized by: the solidus temperature that is of an Al2O3-CaO—SiO2 ternary system slag in said briquette composition and that is determined by the amount of contained Al2O3, CaO, and SiO2 being no greater than 1300 DEG C.; and having an amount of combined carbon material such that the carbon remaining in the direct reduced iron produced by heat treating said briquette composition in the aforementioned moving hearth reduction furnace at a temperature above the aforementioned solidus temperature and below the liquidus temperature of the aforementioned ternary system slag being no more than 6 mass %.
