Description
Technical field
The utility model relates to heat treatment apparatus field, particularly relates to a kind of well formula forvacuum nitriding furnace.
Background technology
Vacuum nitriding furnace is mainly used in the surface Hardening Treatment such as nitriding, multiple permeation, low temperature austenitic nitro-carburizing, cxygen nitrogen coinfiltration, vapor oxidation surface treatment, rough vacuum tempering (or timeliness) of the hardwares such as steel components, tool and mould and survey instrument.Due to the work under bad environment of this kind of heat treatment furnace, higher to the requirement of stove itself, all there is complex structure, fluctuation of service, poor thermal insulation property in current existing vacuum nitriding furnace, energy consumption is high, the shortcoming of product treatment weak effect.
Summary of the invention
In order to solve above-mentioned technical problem, it is more reasonable that the purpose of this utility model is to provide a kind of structure, the well formula forvacuum nitriding furnace of better heat preservation.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of well formula forvacuum nitriding furnace, comprise furnace shell successively from outside to inside, furnace lining flue and vacuum pump, described furnace shell is connected with bell by furnace cover lifting device, described bell is also provided with instrument meter and blower fan, described furnace lining is shaped by multiple high temperature resistant pure aluminium silicate fire-proof fiber module collapsible, described furnace lining is fixed on furnace shell inwall by anchoring piece, described furnace lining inwall is also fixed with resistant to elevated temperatures resistive band by ceramic screw, and be folded with ceramic washer between resistive band and furnace lining, described flue adopts the thick stainless steel materials of 10mm to be welded, and flue and bell are by the seal with elastometic washer of O type, described bell is also connected with vacuum pump by pipeline.
Preferably: described lining thickness is at least 300mm, described bell adopts A3 steel plate to process.Furnace lining and the bell of this structure have quick heating, the features such as good heat insulation, greatly reduce energy consumption, have saved use cost.
Preferably: described blower fan comprises centrifugal fan and sealed electric-motor, described centrifugal fan adopts that 310S is stainless steel welded to be made, and described sealed electric-motor adopts water cooling.
Compared with prior art, the beneficial effects of the utility model are: because furnace lining adopts fully fibrous structure, lagging material heatproof 1350 DEG C, lining thickness >=300mm.This structure has quick heating, and the features such as good heat insulation greatly reduce energy consumption, has saved use cost.Furnace lining inwall is also fixed with resistant to elevated temperatures resistive band by ceramic screw in addition, and its structure installment is convenient, safeguards, changes fast.Be folded with ceramic washer between resistive band and furnace lining, to ensure that fibrous face does not directly contact with resistive band, thus increase the heating effect of resistive band further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
A kind of well formula forvacuum nitriding furnace as shown in Figure 1, comprise furnace shell successively from outside to inside, furnace lining 5 flue 7 and vacuum pump 8, described furnace shell embeds and is arranged in ground 9, described furnace shell is round shape, it is formed by shaped steel and Plate Welding, described furnace shell is connected with bell 2 by furnace cover lifting device 1, described bell 2 is also provided with instrument meter 3 and blower fan 4, described furnace lining 5 is shaped by multiple high temperature resistant pure aluminium silicate fire-proof fiber module collapsible, described furnace lining 5 is fixed on furnace shell inwall by anchoring piece, described furnace lining 5 inwall is also fixed with resistant to elevated temperatures resistive band 6 by ceramic screw, its structure installment is convenient, safeguard, change quick.Be folded with ceramic washer between resistive band 6 and furnace lining 5, to ensure that fibrous face does not directly contact with resistive band, thus increase the heating effect of resistive band.Ceramic screw and packing ring all adopt corundum material at high temperature to sinter and form, and ensure that it has enough intensity and work-ing life.The stainless steel materials that described flue 7 adopts 10mm thick is welded, and flue 7 and bell 2 are by the seal with elastometic washer of O type, and described bell 2 is also connected with vacuum pump 8 by pipeline.
Described furnace lining adopts fully fibrous structure, and Whole fiber adopts Luyang, Shandong high-quality high temperature resistant pure aluminium silicate fire-proof fiber module collapsible to be shaped, and lagging material heatproof 1350 DEG C, is fixed on body of heater with anchoring piece.When production is installed, first, tile two-layer fire-retardent fiber felt-rug as insulating pad layer at the fissure of displacement on furnace wall, then aluminosilicate refractory fiber module is installed, is anchored on furnace wall with high temperature steel anchoring piece, lining thickness >=300mm.This structure has quick heating, and the features such as good heat insulation greatly reduce energy consumption, has saved use cost.
Described bell 2 adopts A3 steel plate to process.Described blower fan 4 comprises centrifugal fan and sealed electric-motor, and described centrifugal fan adopts that 310S is stainless steel welded to be made, and assemble after dynamic and static balance check, described sealed electric-motor adopts water cooling.
