Abstract
The invention provides an energy-saving heat treatment well type heating furnace which comprises a furnace body, a furnace cover, a belt-shaped electric heater, an electric fan and a furnace cover moving mechanism. The furnace body is composed of a furnace wall and a furnace bottom, the furnace bottom is built by refractory bricks, the belt-shaped electric heater is fixed on the inner wall of the furnace wall, and both the furnace wall and the furnace cover are made from alumina silicate fibers. The furnace body is fixedly arranged in a furnace outer shell body made of metal, and a furnace cover outer shell body is fixed on the outer wall of the furnace cover. The using average temperature of the furnace wall and the furnace cover made from the alumina silicate fibers is 980 DEG C, the average degree of fire resistance is 1,100 DEG C, the volume density is within 2.52 to 2.53g/cm3, a heating wire is shrunk lower than 110 DEG C and is within 1.96 to 2.02% in 24 hours, the breaking strength is 0.03MPa, and the heat conduction coefficient is 0.094w/m.k. The energy-saving heat treatment well type heating furnace has the advantages of low heat conduction coefficient, less heat accumulation, quick temperature rising, good integrity, no seams, good heat-preservation effect, less radiating losses, energy saving and the like (more than 30% energy consumption can be saved). Moreover, the heating furnace not only can effectively prevent the internal temperature of the furnace from spreading to the outside of an electric furnace, but also can reduce heat losses and prolong the service life of the furnace body.
Description
Technical field
The present invention relates to a kind of metal heat treatmet process furnace, particularly relate to a kind of body of heater, bell is the well formula heat treatment furnace of aluminum silicate fiber.
Background technology
Heat treatment well type heating furnace is an indispensable heating installation in the metal heat treatmet.The body of heater of process furnace such as the cementing furnace that has used at present, soaking pit, annealing furnace, hotblast stove all is by the stove outer covering body with in the stove outer covering body refractory brick furnace lining to be set to constitute, and bell is the metal bell.The shortcoming of this process furnace is that heat-up rate is slow, and heat-insulating property is poor, wastes energy.In addition, also exist the manufacturing cycle long, consumptive material is many, manufacturing cost is high, body of heater such as is lacked work-ing life at problem.
Summary of the invention
The objective of the invention is above-mentioned shortcoming, and a kind of good heat insulating, thermo-efficiency height are provided, save the heat treatment well type heating furnace of the energy at existing pit furnace existence.
The technical scheme that adopts is:
Energy-saving heat treatment well type heating furnace adopts the pure aluminium silicate spraying to manufacture thermal insulation layer, replaces traditional thermal insulation layers such as refractory brick, comprises body of heater, furnace bottom, bell, roof removal mechanism and banded electric heater.
Body of heater is made of aluminum silicate fiber furnace wall and refractory brick furnace bottom.Bell is the aluminum silicate fiber bell.
Aluminum silicate fiber furnace wall and aluminum silicate fiber bell are made by conventional spray gun spraying aluminum silicate fiber coating.Aluminum silicate fiber furnace wall and bell use temperature mean value are 980 ℃, and refractoriness mean value is 1100 ℃, volume density 2.52-2.53g/cm
3, heater wire is contracted under 110 ℃, and 24 hours is 1.96% to 2.02%, and folding strength is 0.03Mpa, and thermal conductivity is 0.094w/m.k, above data are detected by inspection center of Liaoning Technology University and provide.
Above-mentioned body of heater is arranged in the metal stove outer covering, constitutes the furnace lining of body of heater shell.Be fixed with metal stove enclosing cover on the outer wall of bell upper end.
Adopt aluminum silicate fiber to make furnace wall and bell, make the present invention have following advantage:
Thermal conductivity is low, accumulation of heat is few, heat-up rate is fast, good integrity, no seam, high insulating effect, heat lost by radiation are little, electric furnace surface temperature in the time of 850 ℃ has only between 38 ℃-40 ℃, hang down more than 30 ℃ for 70 ℃ than national electric furnace industry standard, (can save energy consumption more than 30%) economizes on resources, can prevent effectively that temperature is to the stove external diffusion in the stove, reduce the loss of heat, improved converter life.Aluminum silicate fiber furnace wall and bell volume density be low, in light weight, reduced body of heater weight.
