In these years, the development of innovative energy saving technologies for climate change is strongly desired, and low reducing agent ratio (RAR) operation in the blast furnace is required to reduce CO2 emission in ironmaking. As a mean of realizing low RAR operation, the development of an innovative raw material “Carbon Iron Composite (CIC)” for satisfying both high coke reactivity and iron ore reduction is thought to be useful. Carbon Iron Composite is produced by mixing the non-or slightly caking coal and low-grade iron ore and briquetting, followed by carbonization of the briquetted materials. Carbon Iron Composite having both high strength and high reactivity was successfully produced at the blending ratio of iron ore of 30 mass%. Investigation of CO2 reactivity of CIC at the simulated blast furnace condition revealed that beginning temperature of CO2 reaction of CIC is lower than the temperature of conventional coke. Especially, CIC made from high volatile matter coal and porous iron ore has high reactivity and high strength after CO2 reaction.
