Abstract

PURPOSE: To equalize the heat depriving amount and heat accumulating amount in each hot stove and supply a constant volume of hot air at specified temperature always stably to the blast furnace, by providing a ventilation resistance adjusting device in the blow branch tube in each hot stove, when blowing hot air into the blast furnace from the hot stove in the stackered parallel blowing system.
CONSTITUTION: Blow butterfly valves BBV1WBBV4 are provided in ventilation blow branch tubes 46 located between blow valves BV1WBV4 and main ventilation blow pipes 41 leading to four hot stoves 1HSW4HS for a blast furnace BF. When blowing hot air into the blast furnace BF, the opening degree of these butterfly valves is properly adjusted, and the ventilation resistance in each hot stove is adjusted, and by the hot air from plural hot stoves blowing hot air by overlapping therewith, the specified temperature and blow volume may be always maintained in a hot air main pipe 42. Thus, since hot air of constant conditions may be supplied always to the blast furnace, the furnace conditions may be stabilized.
