摘　　要：The zinc vapor condenses on the top of the blast furnace and adheres to the furnace wall, causing the furnace wall to thicken and nodulate, which affects the smooth operation of the furnace. It can block up the gas up pipe and down pipe, damage the body of the blast furnace and reduce the service life of the first generation of the blast furnace. The small sleeve of tuyere is bonded to prolong the treatment time of air rest, and the middle sleeve of tuyere is deformed to cause air leakage, which brings hidden danger to production. Zinc rich liquid drops on tuyere and burns cooling equipment, which is not conducive to high production, low consumption and long life of blast furnace.
