A coke layer and an ore layer are formed in a blast furnace. The coke layer is formed of conventional coke and the ore layer is formed of carbon iron composite, conventional coke, and ore. The mixing percentage of the conventional coke in the ore layer with respect to the ore is 0.5 mass % or more. Slowing of the gasification reaction of carbon iron composite in the cohesive zone can be suppressed. |
