Abstract: A method for charging raw materials into a blast furnace is as follows. The blast furnace includes a bell-less charging device that includes a plurality of main hoppers and an auxiliary hopper. The auxiliary hopper has a smaller capacity than the main hoppers. The method includes discharging ore charged in at least one of the plurality of main hoppers, and then sequentially charging the ore from a furnace wall side toward a furnace center side by using a rotating chute. The discharging of low-reactivity ore charged in the auxiliary hopper is started simultaneously with a start of charging of the ore or at a point in time after the start of the charging; and then, the low-reactivity ore is charged together with the ore from the rotating chute. The charging of the low-reactivity ore is stopped at least before a point in time at which charging of 56 mass % of the ore is completed.
