Abstract
Provided is a slag removal device for a blast furnace, capable of readily and reliably achieving slag removal using a simple device configuration, even when pulverized coal is used that has not had the softening temperature thereof adjusted, and capable of reducing as much as possible the risk of pipe damage, etc. The slag removal device for a blow pipe is provided in a blow pipe that injects auxiliary fuel pulverized coal together with hot air from a tuyere for a blast furnace main body that produces pig iron from iron ore. A jet nozzle that injects solids having a higher fusion point than the temperature in the vicinity of the tuyere and having a particle diameter greater than that of the pulverized coal, into pulverized coal that flows inside the blow pipe and into the hot air, is provided in the slag removal device.
