Increasingly by the favor of people.Cermet heating element is other than integrally formed main structure, as needed, can also be outside it
Add flange arrangement in portion.Ceramic glue is mostly used between cermet heating element and ceramic flange at present or silica gel is bonded, and these glue
After frequent temperature change, it is easy cracking, causes the sealing performance of cermet heating element and flange connections bad,
And these glue are oxidized easily and generate color change, and it is not beautiful enough.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides the connections of a kind of cermet heating element and flange
Method, the cermet heating element connected by this method and flange stability are high, good seal performance.
The technical solution adopted by the present invention to solve the technical problems are as follows:
A kind of connection method of cermet heating element and flange comprising the steps of:
There is provided cermet heating element to be connected, flange and the glaze as connection medium, wherein cermet heating element
For cylindrical body, the flange is ring body, and the glaze is in solid-state or liquid；
Annular gap slot is opened up on the inside of the upper surface of flange；
Cermet heating element and flange are placed in positioning tool, wherein flange sleeve outside cermet heating element,
Flange keeps horizontality；
Glaze is placed in annular gap slot；
Positioning tool, cermet heating element, flange and glaze are put into togerther in continuous tunnel furnace and are sintered；
After cooling, the connector of cermet heating element and flange is obtained.
As an improvement of the above technical solution, in sintering, H is filled with into continuous tunnel furnace2, H2Squeeze out the sky in continuous tunnel furnace
Gas.
As an improvement of the above technical solution, in sintering, tunnel in-furnace temperature is 1050~1100 DEG C, soaking time 2
Hour.
As an improvement of the above technical solution, the positioning tool has for placing cermet heating element and flange
The hole shoulder of stepped hole, the stepped hole is horizontality, and the lower part of the cermet heating element is protruded into stepped hole, the method
Orchid is placed on the hole shoulder of stepped hole.
As an improvement of the above technical solution, the positioning tool is made of ceramics or graphite.
The beneficial effects of the present invention are as follows:
The connection method of this cermet heating element and flange is using glaze as medium by cermet heating element and flange
It is attached, since the heating temperature of cermet heating element does not exceed the melt temperature of glaze, is passing through metal ceramic heating
After the frequent temperature change of body, glaze is not in the situations such as cracking, good seal performance；And the color of glaze is Transparent color, is passed through
It is round and smooth glossy to be sintered rear surface, and is not easy oxidation by air, relatively beautiful, high temperature resistant, environmental protection.
Detailed description of the invention
With reference to the accompanying drawing and specific embodiment the invention will be further described, in which:
Fig. 1 is the structural schematic diagram for the connector that the embodiment of the present invention obtains；
Fig. 2 is the longitudinal profile schematic diagram of flange in the embodiment of the present invention；
Fig. 3 is the longitudinal profile schematic diagram of positioning tool in the embodiment of the present invention.
Specific embodiment
Referring to figure 1, figure 2 and figure 3, the connection method of a kind of cermet heating element and flange of the invention, comprising following
Step: cermet heating element 1 to be connected, flange 2 and the glaze 3 as connection medium are provided, wherein cermet heating element
1 is cylindrical body, and the flange 2 is ring body, and the glaze 3 is in solid-state or liquid；Annular notch is opened up on the inside of the upper surface of flange 2
Slot 21；Cermet heating element 1 and flange 2 are placed in positioning tool 4, wherein 2 sets of flange in cermet heating element 1
Outside, flange 2 keeps horizontality；Glaze 3 is placed in annular gap slot 21；By positioning tool 4, cermet heating element 1, method
Orchid 2 and glaze 3 are put into togerther in continuous tunnel furnace and are sintered；After cooling, the connector of cermet heating element and flange is obtained.
Further, before sintering, can the cermet heating element be polished and is cleaned respectively with flange, increased and connect
The roughness for meeting place washes the impurity of polishing bits and surface, makes connection stronger.In sintering, H is filled with into continuous tunnel furnace2,
H2Squeeze out the air in continuous tunnel furnace, form protective atmosphere, avoid cermet heating element 1, flange 2 and glaze 3 at high temperature by
Oxidation.Tunnel in-furnace temperature is 1050~1100 DEG C, soaking time 2 hours, fills cermet heating element 1, flange 2 and glaze 3
Divide sintering.
Wherein, positioning tool 4 used by the present embodiment has the rank for placing cermet heating element 1 and flange 2
The hole shoulder in terraced hole 41, the stepped hole 41 is horizontality, and the lower part of the cermet heating element 1 is protruded into stepped hole 41,
The flange 2 is placed on the hole shoulder of stepped hole 41, is positioned to cermet heating element 1 and flange 2, and guarantees flange 2
In horizontality.The positioning tool 4 is made of ceramics or graphite, guarantees positioning tool 4 not because high temperature generates deformation even
Melt, and itself and cermet heating element 1 or flange 2 is avoided to react.
In addition, in the present embodiment, glaze 3 is in solid-state before sintering, liquid is molten into sintering, and send out with cermet
Hot body 1 and flange 2 became one, solid glaze before sintering will not the gap between flange 2 and cermet heating element 1 flow to
The position that connection is not needed in cermet heating element 1, using more convenient.
The connection method of this cermet heating element and flange is using glaze as medium by cermet heating element and flange
It is attached, since the heating temperature of cermet heating element does not exceed the melt temperature of glaze, is passing through metal ceramic heating
After the frequent temperature change of body, glaze is not in the situations such as cracking, good seal performance；And the color of glaze is Transparent color, is passed through
It is round and smooth glossy to be sintered rear surface, and is not easy oxidation by air, relatively beautiful, high temperature resistant, environmental protection.
The above, only better embodiment of the invention, but the present invention is not limited to above-described embodiments, as long as
The technical effect of the present invention is achieved by any identical or similar means for it, all should belong to protection scope of the present invention.
