Abstract

Provided is a method for operating a blast furnace that makes it possible to control the component concentration of a blast furnace raw material to a target component concentration even when the component concentration of a sintering raw material fluctuates. The blast furnace operation method in which a blast furnace raw material containing product sintered ore, lump iron ore and an auxiliary raw material is charged into a blast furnace comprises: a sintering step for sintering a sintering raw material to form a sintered cake; a crushing step for crushing the sintered cake into sintered ore; a cooling step for cooling the sintered ore; a sieving step for sieving the cooled sintered ore into product sintered ore and return ore; a measuring step for measuring the component concentration of at least one of the cooled sintered ore, product sintered ore and return ore; and an adjustment step for adjusting blending amounts of the product sintered ore, the lump iron ore and the auxiliary raw material that are contained in the blast furnace raw material. In the adjustment step, the blending amounts of the product sintered ore, the lump iron ore and the auxiliary raw material in the blast furnace raw material are adjusted using the component concentration measured in the measuring step.
