Abstract

PURPOSE:To improve the efficiency and the stability of the operation of the blast furnace, by equipping the avlve part for changing the area of passage of hot air at the part of bent pipe of the branch pipe between the circular pipe of the duct for blowing hot air and the tuyere of the blast furnace and controlling thus the quantity of hot air ejected from each of the tuyere.
