FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly, to blast-furnace production. Method for feeding gases into a shaft furnace, in particular a blast furnace, includes feeding into the furnace at least one gas with creation of shock waves, at that, creating the shock waves, which propagate with the progressive speed, which is more than the speed of sound in the quiet state before the shock wave of the medium, wherein shock waves are initiated by opening again closed valve, which is opened in less than 6 ms, in particular, in less than 4 ms.
EFFECT: enabling acceleration of furnace reaction processes.
