摘要： A method of operating a blast furnace comprising two or more lances that inject reducing agents from a tuyere including injecting a solid reducing agent and a flammable reducing agent from different lances; and arranging a position of an end of the lance that injects the flammable reducing agent closer to a near side in a injecting direction by more than 0 to 50 mm than a position of an end of the lance that injects the solid reducing agent.

摘要： A method of operating a blast furnace includes two or more lances that inject reducing agents from a tuyere; injecting a solid reducing agent and a flammable reducing agent from different lances; and disposing the lances so that an axial line that extends from an end of the lance that injects the solid reducing agent and is the axial line of the lance that injects the solid reducing agent and an axial line that extends from an end of the lance that injects the flammable reducing agent and is the axial line of the lance that injects the flammable reducing agent cross each other, and so that a main flow of the solid reducing agent injected and a main flow of the flammable reducing agent injected overlap.
