Abstract
The utility model discloses a hard felt composite structure of a sintering furnace. The hard felt composite structure comprises a furnace door hard felt which is fixed on the inner side of the furnace door of the sintering furnace and a furnace body hard felt which is fixed on the furnace body of the sintering furnace, wherein the furnace door hard felt and the furnace body hard felt together with the furnace door are fastened with the furnace body, so as to form mutually closely adhering; the furnace door hard felt is embedded into the furnace door of the sintering furnace and provided with fastening grooves, the fastening grooves are fastened with the convex parts on the corresponding positions of the furnace body hard felt to form a shape like Chinese character 'hu', so as to form a sealing structure of the furnace door of the sintering furnace. The hard felt sealing principle of the prior art is continuously utilized, the furnace door hard felt and the furnace body hard felt are modified, so that the furnace door hard felt and the furnace body hard felt are cooperated in the fastening way, furthermore the close degree of the cooperation of the furnace door hard felt and the furnace body hard felt is increased, the clearances are reduced, the thermal insulation effect is improved, and simultaneously the energy is saved.
Description
Technical field
The utility model relates to the hard felt composite construction of a kind of sintering furnace, by International Patent Classification (IPC) (IPC), divides and belongs to agglomerating plant technical field of sealing technology.
Background technology
Sintering furnace is at high temperature a kind of, makes the mutual binding of ceramic green solid particle, grain growth, space (pore) and crystal boundary gradually reduce, and by the transmission of material, its cumulative volume shrinks, density increases, and finally becomes the stove and accessory with certain microstructural dense multicrystalline sintered body.Therefore, in the lifting of its temperature and stove, heat insulation effect is of crucial importance.
Sintering furnace is mainly used in steel industry, metallurgy industry, electron trade etc.Industrial circle sintering furnace has been contained most high temperature sintering furnace on market, according to industry, divide, the kind of sintering furnace mainly contains: 1. carbide alloy field: vacuum sintering furnace, low pressure (60bar) sintering furnace, vacuum degreasing fritting furnace, the degreasing sintered stove of low pressure, the degreasing sintered air-quenching furnace of low pressure (20bar) is field of powder metallurgy 2.: continuous mesh belt type sintering furnace (1150 degree), push-down sintering furnace (1250 degree), steel band sintering furnace (1000 degree), 3. field of solar energy such as swinging sintering furnace: polycrystalline silicon ingot or purifying furnace also belongs to a kind of of sintering furnace.The board equipment in the canyon carbide alloy field that we mainly produce.
The sintering of carbide alloy is to heat under vacuum condition, carries out vacuum dewaxing and sintering process, is conducive to despumation, improves sintering atmosphere purity, improves the wetability of Binder Phase, promotes reaction; Under sintering temperature, process pressurization, on product, promotes that product is further densified simultaneously, eliminates the defect of product, improves the combination property of product.Pressed compact is placed in to vacuum-sintering atmosphere and heats, along with the rising of temperature, while reaching paraffin evaporating temperature, paraffin is overflowed from pressed compact, is incubated enough time during paraffin vapor partial pressure under being less than this temperature, and paraffin is discharged completely from pressed compact, and reclaim by catching wax device, pressed compact is purified.Along with temperature further raises, there is degassed reaction and further purify in pressed compact, solid-phase sintering occurs thereupon.In whole sintering process, sintered body is fine and close in approaching imporosity, and produces series of physical chemical action and institutional framework adjustment, final formation carbide alloy fine and close, that have certain chemical composition, physical and mechanical property, institutional framework
At present, existing sintering furnace all adopts hard felt as the hermetically-sealed construction of fire door and body of heater, and its structure as shown in Figure 1, is the hard felt 1 of fire door
,with the hard felt 2 of body of heater
,directly laminating is upper, and laminating whether be tight the tightness degree decision that coordinated with body of heater by fire door, so extremely easily occurs gap, and the effect of insulation is bad.
Thus, the inventor is through considering for many years and the time improves existing fire door of sintering furnace and furnace sealing structure, and this case produces thus.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of simple and reasonable, convenient to use, good airproof performance, realizes the hard felt composite construction of fire door of sintering furnace of heat insulation function.
For achieving the above object, the utility model is achieved through the following technical solutions:
A hard felt composite construction, this hard felt composite construction comprises and is fixed on the hard felt of fire door of fire door of sintering furnace inner side and is fixed on the hard felt of body of heater in sintering furnace body, and the hard felt of described fire door and the hard felt of body of heater are with fire door and body of heater fastening, and realization fits tightly mutually; The hard felt of described fire door is embedded in fire door of sintering furnace, and is provided with draw-in groove on it, the mutual clamping of projection of the hard felt correspondence position of described draw-in groove and body of heater, and be " mutually " font, form fire door of sintering furnace hermetically-sealed construction.
Further, all sides of the hard felt of described fire door are also provided with hard felt seal circle.
The utility model has continued the principle that the hard felt of prior art utilization seals, at the hard felt of fire door and the hard felt of body of heater, originally improved with it, when the hard felt of fire door is coordinated with the hard felt of body of heater, being clamping forms, and then increase the tightness degree that the hard felt of fire door coordinates with the hard felt of body of heater, thereby reduce gap, to improve heat insulation effect, realize energy-conservation object simultaneously.
Accompanying drawing explanation
Fig. 1 is prior art structural representation;
Fig. 2 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to shown in Fig. 2, the hard felt composite construction of a kind of sintering furnace, this hard felt composite construction comprises and is fixed on the hard felt 1 of fire door of fire door of sintering furnace inner side and is fixed on the hard felt 2 of body of heater in sintering furnace body, the hard felt 1 of described fire door fastens with fire door and body of heater with the hard felt 2 of body of heater, realizes and mutually fitting tightly; The hard felt 1 of described fire door is embedded in fire door of sintering furnace, and on it, is provided with draw-in groove 11, and the mutual clamping of projection 12 of described draw-in groove 11 and hard felt 2 correspondence positions of body of heater, forms fire door of sintering furnace hermetically-sealed construction; The all sides of the hard felt of described fire door are also provided with hard felt seal circle 3.The hard felt 1 of described fire door fastens and forms " mutually " character form structure with fire door and body of heater with the hard felt 2 of body of heater, effectively reduces gap, and then strengthens the heat insulation effect of fire door, also can reach the effect of energy-conserving and environment-protective simultaneously.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
