Description
Technical field
The utility model is specifically related to a kind of graphitizing device for acheson furnace.
Background technique
When acheson furnace is graphitized product, product is placed in furnace in graphitization crucible, earthenware
Crucible must be there are at a distance from 0.5-0.8 meters between furnace wall, and crucible requires heat to 3000 degrees Celsius and carries out stone to product in it
Mo Hua, furnace body are built by high-alumina brick, the resistance to degree for bearing high temperature of high-alumina brick at 1400 degrees Celsius hereinafter, therefore crucible and furnace wall it
Between need to fill after-smithing petroleum coke (0-1 mm dia) and be thermally shielded, make its furnace wall bearing temperature at 1400 degrees Celsius or less.
After-smithing petroleum coke belongs to green coke, can partially be graphitized when which passes through 2000 degrees Celsius or more, which passes through 3000
It degree Celsius can be graphitized completely, petroleum coke has very big purposes after being graphitized, such as makees carburant, and after-smithing petroleum coke passes through
Itself value will increase 40% or more after crossing graphitization, can increase very big economic benefit.
When being graphitized to product in crucible in furnace, edge petroleum coke also can be partially graphitized in furnace, increase its warp
It helps benefit, but the problem is that, the temperature for wanting the petroleum coke to be graphitized completely needs must be at 2000 degrees Celsius or more, and furnace
Wall can only bear 1400 degrees Celsius of temperature, so in process of production in order to guarantee that furnace body is not damaged, petroleum coke will not be by
Graphitization completely, and then economic benefit is restricted.
Utility model content
In order to solve after-smithing petroleum coke in graphitizing process, furnace wall can damage the utility model because of high temperature, raw stone
Oil coke will not provide a kind of graphitizing device for acheson furnace by complete graphited problem.
The utility model adopts the technical scheme that solve above-mentioned technical problem:
It includes crucible, furnace wall, conductive wall and two three layers of furnace cores, and crucible setting is in two furnace walls and two conductive walls
Between, two three layers of furnace cores found the inner plating of intermediate plate and neighbouring crucible in the two sides of crucible, each three layers of furnace core
Between filled with graphitization focus layer, the intermediate plate in each three layers of furnace core and between the lamina rara externa far from crucible filled with raw stone
Oil coke layer, each of neighbouring furnace wall side is between the lamina rara externa and furnace wall of three layers of furnace core filled with graphitization focus layer, Mei Gesan
Layer furnace core is equipped with suspension hook, is filled with raw petroleum coke layer between two three layers of furnace cores.
The utility model has the advantages that compared with prior art
One, filled with graphitization focus layer between the lamina rara externa and furnace wall of each furnace core of neighbouring furnace wall side, in raw stone
When oil coke layer is graphitized completely, since graphitized coke layer resistivity is less than the resistivity of raw petroleum coke layer, graphitization focus layer is produced
Raw temperature is relatively low, and the heat of transmitting is less, accelerates the speed of raw petroleum coke layer heating, and raw petroleum coke layer is graphitized
When furnace wall temperature lower than 1400 DEG C and complete production, on the one hand ensure that the service life of furnace wall, on the other hand save electricity
Energy.
Two, it is improved between the intermediate plate in each three layers of furnace core and the lamina rara externa far from crucible filled with raw petroleum coke layer
Product graphited yield, greatly improves economic benefit.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
Specific embodiment 1: illustrate present embodiment in conjunction with Fig. 1, present embodiment it include crucible 6, furnace wall 2, lead
Electric wall 3 and two three layers of furnace cores 1, the setting of crucible 6 is between two furnace walls 2 and two conductive walls 3, two three layers of furnace cores 1
It stands between the inner plating of intermediate plate and neighbouring crucible 6 in the two sides of crucible 6, each three layers of furnace core 1 filled with graphitization
Raw petroleum coke layer, neighbouring furnace are filled between focus layer, the intermediate plate in each three layers of furnace core 1 and the lamina rara externa far from crucible 6
It is filled between the lamina rara externa and furnace wall 2 of three layers of each of 2 side of wall furnace core 1 and is graphitized focus layer, on each three layers of furnace core 1
Equipped with suspension hook 4, raw petroleum coke layer is filled between two three layers of furnace cores 1.
Raw petroleum coke layer, raw stone are filled between intermediate plate in each three layers of furnace core 1 and the lamina rara externa far from crucible 6
Oil coke layer is equipped with graphite, and one is to speed up graphited speed, second is that improving the graphited yield of product.
Specific embodiment 2: illustrate present embodiment in conjunction with Fig. 1, each three layers of furnace core 1 of present embodiment
In connected by multiple crossbeams between two neighboring plate.
Other compositions and connection relationship are same as the specific embodiment one.
Specific embodiment 3: illustrate present embodiment in conjunction with Fig. 1, each three layers of furnace core 1 of present embodiment
In the distance between two neighboring plate be 100mm.
Other compositions and connection relationship are identical with embodiment two.
Specific embodiment 4: illustrate present embodiment in conjunction with Fig. 1, the institute of two three layers of furnace cores 1 of present embodiment

The course of work
Before the energization of conductive wall 3, two three layers of furnace cores 1 are extracted out out of furnace, the electric current of conductive wall 3 passes through raw petroleum
Focus layer, since the resistivity of raw petroleum coke layer is big relative to the resistivity of graphitization focus layer, so that raw petroleum coke layer is being graphitized
During temperature it is higher than the temperature for being graphitized focus layer, while to guarantee the inner plating of two three layers of furnace cores 1 to respective
The distance L1 of the furnace wall 2 of side is 700mm, reduces the heating rate of furnace wall, raw when the temperature of raw petroleum coke layer rises to 2000 DEG C
Petroleum focus layer starts to be graphitized, and when the temperature of raw petroleum coke layer region reaches 3000 DEG C, the temperature of furnace wall is lower than 1400 DEG C, this
When completed the graphitization work of product in furnace.
