To provide a charge method, even in the case coke is mixed into ores and the mixture is charged, capable of uniformizing the coke distribution of the ores compared with the conventional case.SOLUTION: A bell-less blast furnace comprises a process where mixed raw material of ores and coke is temporarily stored in a furnace top hopper, and the same is charged into a furnace from the furnace top hopper by a swing chute to form a mixed layer, in which, regarding the mixed raw material, an integrated dimensionless charge amount when the dimensionless exhaust time of the mixed raw material is 0.5 is 0.1 to 0.45, and the charge method includes: a first mixed raw material charge step S1 where the mixed raw material is deposited in forward tilt from a position of 0.7 to 1.0 in a throat dimensionless radius to a position in which the same is overlapped with a part or the whole of a central coke layer in the case the central coke layer is formed and to a position of 0 to 0.2 in a throat dimensionless radius in the case the central coke layer is not formed; and a second mixed raw material charge step S2 where the mixed raw material id deposited in forward tilt from a position of 0.8 to 1.0 in a throat dimensionless radius to a position of 0.3 to 0.5 in a throat dimensionless radius.SELECTED DRAWING: Figure 1
