Traditional graphitizing furnace is acheson furnace, be in the way of indirectly heat based on, constitute conductive combustion chamber
It is the particulate material of the blank of charcoal as product and the charcoal as resistance material.Although product is the resistance of heating, it is also to be added
The object of heat, the heat needed for product graphitization is mainly by the heat transfer of resistance material.The heating of product be first from surface start again by
Gradually internally penetrate into, the mode of this external heat causes temperature distributing disproportionation and produces thermal stress, the heat conduction of general carbon product
Property all poor, when furnace temperature rises very fast it is possible to produce situation significantly uneven in temperature, crackle waste product occurs.
A kind of Super-high temperature graphitization treatment equipment of the disclosure of the invention of Application No. 2014100162970, including furnace shell, stove
Is disposed with the feed space being interconnected, heating chamber and discharge chamber along material conveying direction in shell, feed space and heating chamber it
Between be provided with charging insulated door, be provided with discharging insulated door between heating chamber and discharge chamber, furnace shell be provided with and discharge chamber phase
The quick cooling system of cooperation, furnace shell to be internally provided with the material matching respectively with feed space, heating chamber and discharge chamber defeated
Send device；Charging interior is provided with the first vacuum extractor cooperating and the first air intake installation, and heating interior is provided with phase
Mutually the second vacuum extractor of cooperation and the second air intake installation, discharging interior be provided with the 3rd vacuum extractor cooperating and
3rd air intake installation, furnace shell is provided with and is matched with the first vacuum extractor, the second vacuum extractor and the 3rd vacuum extractor
The vacuum pump set closing.The electrode tip of this processing equipment easily produces pit, resistivity is difficult to ensure that satisfaction requires.
Content of the invention
Goal of the invention:
There is provided that an a kind of batch is many, electrode end surface does not have the pitted graphite anode for magnesium electrolysis of resistance to high current substantially
Graphitizing device.
Technical scheme:
This utility model is related to a kind of graphitizing device of the graphite anode for magnesium electrolysis of resistance to high current, has Packed stove
Wall, is burner hearth inside furnace wall, and the length of burner hearth is more than the length sum of two or many graphite anode blanks, and each two series connection is even
Soft graphite ring is employed as connector, to improve electric conductivity, to reduce between electrode between the graphite anode blank connecing
Collision.Between the axial external surface (parallel to central axial outer surface) of furnace wall and graphite anode blank, there is filled insulation layer
(using the preferable metallurgical coke of the substantially different insulating properties of size as filled insulation), outermost graphite anode blank
End is connected with anelectrode or negative electrode after being connected with a conductive regulating block more respectively, and positive and negative electrode passes through furnace wall respectively
Two ends.
The width of burner hearth is preferably greater than the diameter sum of two graphite anode blanks, can by two graphite anode blanks simultaneously
Connection is placed in burner hearth, to improve batch and protection furnace wall, heat-insulated.
During graphitization shove charge, the semi-finished product (blank) after two or many roastings are joined end to end and loads the stone of this equipment
In Mo Hualu, use soft graphite ring pad good between end to end electrode, when installing last, compressed with conductive regulating block,
Calculate and keep suitable pushing tow pressure to realize good electrical contact, head and the tail two ends connect anelectrode or the negative electricity of conduction respectively
Pole, facilitates conductive heater.
In gap between the end of graphite anode blank and body of heater, preferably adopt between the end of two neighboring blank in parallel
Use special filling material；Special filling material is the good metallurgy of the substantially uniform electric conductivity consistent, that particle diameter is 1-5mm of size
Burnt.It is easy to more densely cross-linked, the generation of minimizing electric arc filled out, the side reducing electrode tip produces the effect of pit.
After shove charge, positive and negative electrode is energized, relies primarily on the resistance heat heating electrode that electrode energising itself produces, filler master
Play insulation heat insulating function；Rather than generated heat and deliver heat to electrode as traditional acheson furnace relies primarily on filler
Heating means, electrode quick heating, be heated evenly, filler be heated less, waste electric energy less.Because product is heated concentration, need not
The medium heat-transfer of outside, substantially, cool time can also shorten a few houres to energy-saving effect.
Beneficial effect:
This equipment major technique advantage is:
The utilization of special filling material, reduces the pit of electrode tip both sides side, while presentation quality provides, electrode tip
Surface resistivity is low, during identical voltage-drop loading, can produce and bear bigger electric current, improve the occasions such as the electrolysis of magnesium chloride
The efficiency using.
This equipment batch is more, and production efficiency is higher, can improve the thermal conductivity between them in electrode；And
Adiabatic preferable, reduce thermal loss, reduce thermal loss and power consumption during using.
