Abstract
An energy-saving heating furnace includes a furnace body, a furnace cover, a strip-like 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 from fire-refractory bricks. The strip-like electric heater is fixed on an inner wall of the furnace wall. The furnace wall and the furnace cover are both produced from aluminum silicate fibers. The energy-saving heating furnace is low in heat conductive coefficient, is less in heat accumulation, is high in temperature increasing speed, is good in integrality, is free of seam joints, is good in heat preservation effects, is less in heat dissipation loss, can save resources (reducing more than 30% of energy consumption), can effectively prevent heat dissipation of heat from interior to exterior of the furnace, can reduce heat loss and can prolong 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, well formula heat treatment furnace that bell is aluminum silicate fiber.
Background technology
Heat treatment heating furnace is indispensable heating installation in metal heat treatmet.The body of heater of the process furnace such as cementing furnace, soaking pit, annealing furnace, hotblast stove used at present is all by stove outer covering body and in stove outer covering body, arranges refractory brick furnace lining form, and bell is metal bell.The shortcoming of this process furnace is that heat-up rate is slow, and poor thermal insulation property, wastes energy.In addition, also have that the manufacturing cycle is long, consumptive material is many, manufacturing cost is high, the problem such as body of heater work-ing life is short.
Summary of the invention
The object of the invention is the above-mentioned shortcoming existed for existing pit furnace, and provide a kind of good heat insulating, thermo-efficiency high, save the heat treatment well type heating furnace of the energy.
The technical scheme adopted is: energy-saving heat treatment well type heating furnace, adopts pure aluminium silicate spraying to manufacture thermal insulation layer, replaces the thermal insulation layers such as traditional refractory brick, comprise body of heater, furnace bottom, bell, roof removal mechanism and banded electric heater.Body of heater is made up of aluminum silicate fiber furnace wall and refractory brick furnace bottom.Bell is aluminum silicate fiber bell.Aluminum silicate fiber furnace wall and aluminum silicate fiber bell spray aluminum silicate fiber coating by conventional lance and make.Aluminum silicate fiber furnace wall and bell use temperature mean value are 980 DEG C, and refractoriness mean value is 1100 DEG C, volume density 2.52-2.53g/cm
3, at heater wire is contracted in 110 DEG C, within 24 hours, be 1.96% to 2.02%, folding strength is 0.03Mpa, and thermal conductivity is 0.094w/m.k, and above data are detected by inspection center of Liaoning Technology University and provide.Above-mentioned body of heater is arranged in a metal stove outer covering, forms the furnace lining of body of heater shell.Bell upper end outer wall is fixed with metal stove enclosing cover.
Aluminum silicate fiber is adopted to make furnace wall and bell, tool of the present invention is had the following advantages: thermal conductivity is low, accumulation of heat is few, heat-up rate is fast, good integrity, little without seam, high insulating effect, heat lost by radiation, electric furnace surface temperature 850 DEG C time only has between 38 DEG C-40 DEG C, lower than national electric furnace industry standard 70 DEG C more than 30 DEG C, economize on resources (can save energy consumption more than 30%), in-furnace temperature effectively can be prevented to stove external diffusion, reduce the loss of heat, improve converter life.Aluminum silicate fiber furnace wall and bell volume density low, lightweight, reduce body of heater weight.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiments of the invention.
Embodiment
Energy-saving heat treatment well type heating furnace, comprises body of heater 1, bell 3, banded electric heater 4, electric fan 5 and roof removal mechanism.The furnace bottom 2 that body of heater 1 is built into by aluminum silicate fiber furnace wall 6 and refractory brick is formed.Bell 3 is aluminum silicate fiber bell, and bell 3 be located in the upper port of aluminum silicate fiber furnace wall, and banded electric heater 4 is known electric well heater, is fixed on the inwall of aluminum silicate fiber furnace wall 6.Electric fan 5 is arranged on below bell 3, and fan shaft is connected with the output shaft of motor 8 through bell 3, and motor 8 is fixed on bell 3.Roof removal mechanism comprises bell support plate 9, vertical pivot 10, first wall axle bed 11 and second wall axle bed 12.First and second wall axle beds be arranged in parallel up and down, and are separately fixed on aluminum silicate fiber furnace wall 6, and vertical pivot 10 inserts in the axis hole of first wall axle bed 11 and second wall axle bed 12, rotatable.The upper end of vertical pivot 10 is fixedly connected with bell support plate 9 one end, and the other end of bell support plate 9 is fixedly connected with the housing of motor 8.Roof removal mechanism can make bell 3 do 360 ° of displacements.
