Description
Technical field
The present invention relates to glass manufacturing areas more particularly to a kind of composite material to incude electrical crucible.
Background technology
Currently, glassware is usually all by melting glass raw material, the modes such as then being squeezed, be molded and realizing glass
The molding of product.The fusing of existing glass raw material all just uses crucible to carry out, and is all to use nonconducting corundum crucible
It is typically by coal, natural gas, tung oil and other items burn then heating corundum crucible to realize come what is carried out
's.This mode will produce more problem, such as exhaust gas discharge leads to that environmental pollution, working efficiency are relatively low, cost is higher.It is existing
There is iron and steel smelting industry to have to be operated using graphite crucible, but graphite crucible can not be applied to glass manufacture, because
It can react in fusing between graphite crucible and glass, manufactured glass colour is caused to carry irregular black silk or black
Silk block.And if using graphite crucible as outer layer, the inside is arranged one layer of corundum crucible, due at high operating temperatures, corundum earthenware
The coefficient of expansion of crucible and graphite crucible is different, and thus crucible body can be made to be easy to damage because of expanding with heat and contract with cold.
Invention content
Therefore, for above-mentioned problem, the present invention proposes a kind of composite material simple in structure, can realizing electromagnetic heating
Incude electrical crucible.
To achieve the above object, present invention employs following technical schemes：A kind of composite material induction electrical crucible, including it is rigid
Beautiful layer and the conductive composite layer with elastic telescopic function, the electrically conductive graphite layer being coated on successively outside corundum layer, the biography
Lead the raw material that composite layer includes following parts by weight：35~55 parts of graphite powder, 8~15 parts of kaolin, 10~25 parts of leavening agent,
25~40 parts of high-temperature glue agent.
Further, the conductive composite layer is prepared by the raw material of following parts by weight：40 parts of graphite powder, kaolinite
10 parts of soil, 15 parts of leavening agent, 35 parts of high-temperature glue agent.
Further, the leavening agent is high temperature leavening agent.
Further, the corundum layer is equipped with the blanking hole for penetrating conductive composite layer, electrically conductive graphite layer successively, institute
It states blanking hole and is blocked equipped with one and filled in.
Further, the electrically conductive graphite layer is coated with high-temperature-resistant thermal-insulation layer.
Further, the high-temperature-resistant thermal-insulation layer is ceramic fibre.
By using preceding solution, the beneficial effects of the invention are as follows：This composite material incudes electrical crucible and utilizes corundum
Layer using electrically conductive graphite as outer layer, and adds conductive composite therebetween as the internal layer contacted with glass raw material,
To realize electromagnetic heating electrically conductive graphite, then conductive composite is utilized to realize heat transfer, to realize to corundum crucible
Heating, to realize fusing to glass raw material, since conductive composite is added to graphite powder to heating and pass
Ability is led, is added to leavening agent so that entire conductive composite layer rapid bulk shape after being heated to high temperature for the first time
State stablize after, be in conductive composite layer have a plurality of holes thus have certain elastic restoring force, be added to
High-temperature glue agent is bonded primarily with respect to stablizing for several substances, also increases elastic restoring force to a certain extent, and kaolinite
Soil mainly using its clay mineral, heat safe characteristic, can form the preferable stabilization conductive composite with hole
The harmful effect that can be brought to avoid the corundum coefficient of expansion different from graphite is arranged in layer in this way；Further, the corundum
Layer is equipped with the blanking hole for penetrating conductive composite layer, electrically conductive graphite layer successively, and the blanking hole, which is equipped with one and blocks, to be filled in, under
The setting in material hole can facilitate blanking.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
In conjunction with the drawings and specific embodiments, the present invention is further described.
With reference to figure 1, the present embodiment one provides a kind of composite material induction electrical crucible, including corundum layer 1 and is coated on successively
The conductive composite layer 2 with elastic telescopic function, electrically conductive graphite layer 3, ceramic wool insulation layer 4 outside corundum layer 1, it is described
A plurality of holes 21 are equipped in conductive composite layer 2.The conductive composite layer 2 by following parts by weight raw material prepare and
At：40 parts of graphite powder, 10 parts of kaolin, 15 parts of high temperature resistant leavening agent, 35 parts of high-temperature glue agent.The corundum layer 1 be equipped with according to
The secondary blanking hole 22 for penetrating conductive composite layer 2, electrically conductive graphite layer 3, ceramic wool insulation layer 4 is set on the blanking hole 22
There is a closure plug 5.The corundum layer 1 is downwardly extending a tremie pipe 23 by blanking hole 22.The tremie pipe 23 is from top to bottom
Cross section is gradually reduced
The present embodiment two provides a kind of composite material induction electrical crucible based on same inventive concept, is distinguished with embodiment one
It is：Conductive composite layer 2 includes the raw material of following parts by weight：35 parts of graphite powder, 8 parts of kaolin, 10 parts of leavening agent, high temperature
25 parts of adhesive.
The present embodiment three provides a kind of composite material induction electrical crucible based on same inventive concept, is distinguished with embodiment one
It is：Conductive composite layer 2 includes the raw material of following parts by weight：55 parts of graphite powder, 15 parts of kaolin, 25 parts of leavening agent, height
40 parts of warm adhesive.
This composite material incudes electrical crucible using corundum layer as the internal layer contacted with glass raw material, is made using electrically conductive graphite
For outer layer, and conductive composite is added therebetween, it is then multiple using conduction to realize electromagnetic heating electrically conductive graphite
