Method for charging raw materials into blast furnace

A method for charging raw materials into a blast furnace, the blast furnace including a bell-less charging device that includes a plurality of main hoppers and an auxiliary hopper at a furnace top portion, the auxiliary hopper having a smaller capacity than the main hoppers,

• the method comprising discharging ore (x) charged in at least one of the plurality of main hoppers, the ore (x) having a JIS reducibility index (RI) of greater than 55%, and then sequentially charging the ore (x) from a furnace wall side toward a furnace center side by using a rotating chute, wherein
• discharging of low-reactivity ore (y) charged in the auxiliary hopper is started simultaneously with a start of charging of the ore (x) or at a point in time after the start of the charging, the low-reactivity ore (y) having a JIS reducibility index (RI) of 55% or less, and then the low-reactivity ore (y) is charged together with the ore (x) from the rotating chute;
• and charging of the low-reactivity ore (y) is stopped at least before a point in time at which charging of 56 mass % of the ore (x) is completed based on a total amount of the ore (x) to be charged per batch.
