Specific embodiment
Core of the invention is to be combined with graphitization technique and provide a kind of superhigh temperature graphitization equipment, the superelevation fire stons
The superhigh temperature graphitization process more continuous high-efficient of blackization equipment.
In order that those skilled in the art more fully understand the present invention program, come below in conjunction with the accompanying drawings further specifically
Bright specific embodiment.
Graphitization sample 10 of the present invention reaches primary pre- by the feed system of feed system 7 by the material channel of haul track 8
Heating rod 11 is set in hot stove 1, stove, and primary preheating furnace 1 is closed thermal-insulating sealing system 2 and is passed through nitrogen protection, in primary preheating furnace 1
Middle heating reaches 1200 DEG C by room temperature, and thermal-insulating sealing system 2 is opened afterwards；Heated into two grades of preheating furnaces 3 by 1200 to
1500℃；Heating and thermal insulation realizes carbonisation by 1500 to 1800 DEG C in the carbide furnace of high temperature carbonization furnace 4；Enter superhigh temperature afterwards
Graphitizing furnace 5, temperature is passed through helium-atmosphere gas by 1800 to 2850 DEG C, and the change of carbon material structure is realized in the environment of superhigh temperature
Change, sp2 processes are changed into from sp3, finally enter the cooling cooling stove of stove 6 and be cooled to room temperature；Graphitization is collected by material-receiving system 16
Product.
Heating process is divided into several stages by the present invention so that each stove need not be cooled to room temperature, reduces lifting warm area
Between.Due to being very slow in superhigh temperature heating process, by shortening the heating and cooling interval of stove, heating institute is greatly reduced
The time of consumption.Therefore the design has operating efficiency very high.
By feed system in the present invention, when material enters next stage stove, entered by the material in the stove of upper level
Row supplement, ensure that each stove can be accessed and ceaselessly applies, enabling continuous work.
Each high temperature furnace quickly can be down to specific heating initial temperature by the present invention by the water circulation channel of water channel 12,
Different process can be designed according to material property, realize the adjustment in different heating temperature range, and design specific different phase
The rate of heat addition and soaking time.
