Abstract In view of the problems existing in the former tunnel high一temperature annealing furnace,
情成语design improvements are made.The improvements mainly includes:choosing a suitable type of burners
to ensure the burners work at the rated power;developing multi-stage air distribution ultra-low NO X
burner with large speed difference to improve combustion efficiency and make the N0x emission of the
furnace not exceed80mg/m3;adjusting the installation position of the burners to improve the heat ex
change efficiency and furnace temperature uniformity in the furnace;redesigning the trolley masonry,
which reduces the weight of the trolley and reduces the heat storage of the trolley by35%;spraying
high-temperature infrared coating material on the inner surface of the furnace to improve the radiation
heat transfer of the furnace.Compared with the former annealing furnace,the annealing quality of the
steel coil and the thermal efficiency of the furnace are improved,and the fuel consumption is saved.
Keywords tunnel high temperature annealing furnace high-speed burner lightweight trolley
