Abstract
An energy-saving heat treatment pit furnace comprises a furnace body, a furnace cover, a strip electric heater, an electric fan and a furnace cover moving mechanism, wherein the furnace cover is arranged on the upper end surface of the furnace body to block up the upper opening of the furnace body; the furnace body consists of an aluminum silicate fiber furnace wall and a fire-resistant tile furnace bottom; and the furnace cover is made from aluminum silicate fiber. The utility model has the characteristics of low heat conductivity coefficient, little heat accumulation, high heating rate, good integrity, no seam, good heat insulation effect, little radiation loss, energy saving (energy can be saved by more than 30% ), etc. The utility model can effectively avoid the heat transfer dispersing from the furnace interior, the heat loss is reduced, and the service life of pit furnace body is prolonged.
Description
Technical field
The utility model relates to a kind of metal heat treatmet process furnace, particularly relates 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 purpose of this utility model is the above-mentioned shortcoming that exists at existing pit furnace, and a kind of good heat insulating, thermo-efficiency height are provided, and saves the heat treatment well type heating furnace of the energy.
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 to the utlity model has 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.
