Technical field
The present invention relates to auto parts and components casting field, specifically, is a kind of melting furnace being used for melting aluminum liquid.
Background technology
In auto parts and components processing and manufacturing process, often need solid aluminium ingot to be fused into aluminium liquid and be then cast to the auto parts and components that grinding tool cooling forming becomes various needs, this just needs to use melting furnace, existing melting furnace often structure is simple, do not use heat-insulation layer or heat insulation layer structure single, heat insulation effect is undesirable, therefore in fusing aluminium ingot process, needs more fuel and time, improve production cost, and cause the wasting of resources and environmental pollution.
Summary of the invention
In order to solve the problems of the technologies described above, for auto parts and components manufacturing enterprise provides a kind of melting furnace containing heat-insulation layer, good heat insulation effect can be reached, temperature in body of heater is avoided to decline too fast, the object that the energy reduces production cost is saved to reach, a kind of melting furnace that the present invention discloses, comprise body of heater and crucible, crucible is embedded in body of heater, crucible and body of heater binding site are provided with supporting plate, be provided with refractory plate under supporting plate to play a supporting role, inboard wall of furnace body is provided with the flame retardant coating that refractory brick is formed, refractory brick is provided with holder brick, holder brick is provided with igniter, also heat-insulation layer is provided with outside the flame retardant coating of body of heater, the bottom of body of heater is provided with air inlet, air inlet is through heat-insulation layer and flame retardant coating, one end of air inlet is connected with appendix.
In the technical program, body of heater and crucible are prior aries, the effect one of body of heater is support crucible, two is for crucible provides heat to reach the fusing point of aluminium ingot by gas fuel burning, aluminium ingot is made to be fused into aluminium liquid, the effect of crucible holds solid aluminium ingot and is fused into the aluminium liquid of liquid, crucible and body of heater binding site are provided with supporting plate and play crucible and support fixation and can prevent crucible from toppling over, be provided with refractory plate under supporting plate to play a supporting role, inboard wall of furnace body is provided with the flame retardant coating that refractory brick is formed, flame retardant coating forms a closed combustion chamber confession gas fuel burning, refractory brick is provided with holder brick to be used for igniter is installed, holder brick is provided with igniter and is used for ignited flammable gas, igniter can adopt electronic ignition device to connect outside power switch by wire, reach the effect of long-range igniting, also heat-insulation layer is provided with outside the flame retardant coating of body of heater, temperature in air and the mutual body of heater on earth of outside air is used for preventing in body of heater to decline too fast, the bottom of body of heater is provided with air inlet, air inlet is through heat-insulation layer and flame retardant coating, be used for providing imflammable gas in body of heater, one end of air inlet is connected with appendix.
Further improvement of the present invention, heat-insulation layer is made up of soft-porcelain insulation board, asbestos board and phenolic foam material, heat-insulation layer is outwards followed successively by one deck soft-porcelain insulation board, two-layer asbestos board from inner, and two-layer asbestos board forms a hollow layer, is filled with phenolic foam material in hollow layer.Soft-porcelain insulation board directly contacts with the flame retardant coating of melting furnace as heat insulation layer structure innermost layer, and this is because the character of porcelain tendre material determines, porcelain tendre the porcelain of really, neither ceramic tile, and it is a kind of novel
building and ornament materials, be primary raw material by modification earth, use special temperature control moulding system shaping, baking,
irradiationcrosslinked a kind ofly have flexible building decoration plane materiel, and have quality soft, ductility is good, the advantages such as seismic crack, and also have the character such as high temperature resistant, seismic crack, low cost can also recycle simultaneously; Outside soft-porcelain insulation board, arrange two-layer asbestos board, the core body good permeability of asbestos board, volume stability, intensity is high, hydrophobic, it is high that overall asbestos board has intensity, and anti-impact is shockproof, and overall performance is good, insulation, from heavy and light, sound insulation and noise reduction, space increases, environmental protection, the advantages such as resistance to combustion fire prevention; The hollow layer that asbestos board is formed has the effect of leakproof, therefore inside filled phenolic foamed material, and phenolic foam material belongs to the organic hard of macromolecule
aluminium foilfroth pulp, be by
thermosetting phenolic resinfoaming forms, it has lightweight, fire prevention, chance naked light do not burn, smokeless, nontoxic, without drippage, serviceability temperature is not shunk under enclosing extensively (-196 ~+200 DEG C) low temperature environment, not brittle, it is the desirable heat-insulating material of HVAC Refrigeration Engineering, because phenol formaldehyde foam rate of closed hole is high, then thermal conductivity factor is low, heat-proof quality is good, and have a water resisting property and water vapour permeability, it is desirable heat insulating energy saving material, therefore greatly can alleviate the weight of heat-insulation layer as the filling with insulation material of heat insulation layer structure, be convenient to transport and install.
Further improvement of the present invention, the thickness of soft-porcelain insulation board, between 10-100mm, is preferably 50mm; The thickness of asbestos board, between 10-50mm, is preferably 30mm; The thickness of the described hollow layer that two-layer asbestos board is formed, between 10-50mm, is preferably 30mm.
Further improvement of the present invention, at the outermost layer of heat insulation layer structure, the thick stainless steel bed of material of one deck 5mm is set, be used for fixing heat insulation layer structure, soft-porcelain insulation board, asbestos board, phenolic foam material are sealed in the stainless steel bed of material, also being to prevent phenolic foam material from leaking, playing better heat insulating effect.
Beneficial effect of the present invention: the present invention is a kind of melting furnace making heat-insulation layer containing composite, can reach good heat insulation effect, avoids temperature in body of heater to decline too fast, has and save the advantage that the energy reduces production cost.
