Description
Technical field
This utility model relates to a kind of sintering furnace, especially a kind of alloy vacuum sintering furnace.
Background technology
The manufacturing process of hard alloy generally comprises powder pressing forming, degumming, vacuum-sintering etc., it is finally made hard metal article, but owing to, in scouring processes, the binding agent of alloy powder often cannot thoroughly be removed totally, cause when carrying out vacuum-sintering, the binding agent also having part evaporates, and binding agent can be attached on the heat preservation carbon felt of agglomerating chamber's surrounding, after accumulation a period of time, heat preservation carbon felt can be caused to deform, heat insulation effect reduces, therefore, it is necessary to often change heat preservation carbon felt.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide one to avoid binding agent to be attached to carbon felt heat-insulation layer, makes carbon felt heat-insulation layer have the alloy vacuum sintering furnace of more long life.
For achieving the above object, this utility model is by the following technical solutions:
A kind of alloy vacuum sintering furnace, including body of heater, couveuse, agglomerating chamber, described body of heater includes furnace shell and bell, described couveuse is arranged in the inner chamber of furnace shell, the cross section of couveuse is rectangle, couveuse is followed successively by carbon felt heat-insulation layer and couveuse shell from inside to outside, described agglomerating chamber is arranged on the middle part of couveuse, agglomerating chamber is formed around electric heating body, on described fire door, corresponding couveuse mouth is provided with carbon felt heat-insulation layer, being provided with graphite cake between described agglomerating chamber and carbon felt heat-insulation layer, the carbon felt insulation layer surface on described fire door is provided with graphite ply of paper.
Described electric heating body is graphite heater.
It is provided with silica gel sealing ring between described bell and furnace shell.
Described graphite ply of paper is sewed up fixing with carbon felt heat-insulation layer by connecting line.
This utility model uses above technical scheme, have following technical effect that the surrounding in agglomerating chamber arranges graphite cake, graphite cake can be high temperature resistant, have and binding agent can be stoped to be attached on carbon felt heat-insulation layer, avoid carbon felt heat-insulation layer because adsorbing too much binding agent and deformation failure, carbon felt insulation layer surface on fire door arranges graphite paper, graphite paper equally can also be high temperature resistant, and there is lighter quality and less volume, it is very suitable for the carbon felt heat-insulation layer for stoping binding agent to be attached on fire door, graphite paper can be directly fixed on carbon felt heat-insulation layer by stitching, easy for installation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details:
Fig. 1 is the structural representation of this utility model a kind of alloy vacuum sintering furnace；
Fig. 2 is the structural representation of bell.
Detailed description of the invention
As shown in accompanying drawing 1 or 2, this utility model includes body of heater 1, couveuse 2, agglomerating chamber 3, described body of heater 1 includes furnace shell 11 and bell 12, described couveuse 2 is arranged in the inner chamber of furnace shell 1, the cross section of couveuse 2 is rectangle, couveuse is followed successively by carbon felt heat-insulation layer 21 and couveuse shell 22 from inside to outside, described agglomerating chamber 3 is arranged on the middle part of couveuse 2, agglomerating chamber 3 is formed around electric heating body 5, on described fire door 12, corresponding couveuse mouth is provided with carbon felt heat-insulation layer, graphite cake 4 it is provided with between described agglomerating chamber and carbon felt heat-insulation layer, carbon felt heat-insulation layer 122 surface on described fire door is provided with graphite ply of paper 6.Described electric heating body is graphite heater 5.Silica gel sealing ring 121 it is provided with between described bell and furnace shell.Described graphite ply of paper 6 is sewed up fixing with carbon felt heat-insulation layer 122 by connecting line 7.
This utility model arranges graphite cake 4 in the surrounding of agglomerating chamber, graphite cake 4 can be high temperature resistant, have and binding agent can be stoped to be attached on carbon felt heat-insulation layer, avoid carbon felt heat-insulation layer because adsorbing too much binding agent and deformation failure, carbon felt insulation layer surface on fire door arranges graphite paper 6, graphite paper equally can also be high temperature resistant, and there is lighter quality and less volume, it is very suitable for the carbon felt heat-insulation layer for stoping binding agent to be attached on fire door, graphite paper can be directly fixed on carbon felt heat-insulation layer by stitching, easy for installation.
