Description
Technical field:
The utility model belongs to the metallurgy industry production facility, is specifically related to improved walking beam furnace.
Background technology:
Be heated to be the flat flame burner formula on the walking beam furnace that metallurgy industry is used, be heated to be the segmented ratio control mode of side burner down, being in operation, there are the following problems:
When 1, heating furnace broke down, because burner is more, it was longer to close the required time of the valve of each burner, and the time of corresponding trouble shooting is longer;
2, because the steel kind of producing is more, each breed structure more complicated, adjustment requires the frequent changes operating mode, and in the process of frequent changes operating mode, thermal losses is bigger.
Summary of the invention:
The utility model aims to provide the less a kind of walking beam furnace type of furnace of thermal losses.
The realization the technical solution of the utility model is: comprise body of heater, the side wall of body of heater constitutes three-decker by three kinds of materials, be respectively that thickness is 360 millimeters the low cement bed of material from inside to outside, thickness is 114 millimeters insulating brick layer, thickness is 100 millimeters alumina silicate fiber felt thermal insulation layer, furnace roof is that 30 millimeters alumina silicate fiber felt is heat insulation with the fibre castable sealing by moldable and thickness, body of heater is divided into preheating section, bringing-up section, soaking zone, on the two sides side wall of bringing-up section the accent flame burner nozzle is set, the last bringing-up section of soaking zone is provided with flat flame burner, the following bringing-up section of soaking zone is provided with the accent flame burner nozzle, on the coal gas of accent flame burner nozzle and the Air mixing feed channel magnetic valve and control valve are set, on the coal gas of flat flame burner and the Air mixing feed channel control valve is set, air header road and gas main road are arranged on furnace roof.
By test in hot continuous rolling factory of Shanxi Taigang Stainless Steel Co., Ltd, the utility model is compared with the 0# of this factory walking beam furnace, the utility model not only slab heating quality is improved, and energy consumption index also has bigger decline, at heating standard base, furnace output can reach 200t/h, carbon steel is the 1.38GJ/t steel from unit consumption, drops to the 1.296GJ/t steel, has obtained considerable economic and social benefit.
