Description
[technical field]
The present invention relates to technical field of aluminum electrolysis, particularly relate to eliminate the insulation stretched one's legs in aluminium cell corner
Material and removing method.
[background technology]
The burner hearth of Hall-Ai Lu aluminium cell is the important component part of electrolysis bath, is whole electrolytic process
Basic.But along with the popularization and application of Low Voltage Technique, electrolysis bath heat income reduces, and generally presents
Corner is cooler, and electrolyte solidifies in a large number in corner, stretches one's legs the phenomenon grown up in corner, causes being electrolysed tank furnace
Thorax deformity, horizontal current increases, affects electrolysis bath stability and current efficiency.And, stretch one's legs greatly easily
Bending anode bus, has a strong impact on the properly functioning of electrolysis bath.
The way stretched one's legs in existing process corner has corner insulation method and artificial treatment method.Corner insulation method is logical
Crossing reinforcement corner external thermal insulation to melt and stretch one's legs, its keeping warmth space is little, stretches one's legs and is difficult to melt；Artificial treatment
Method be anode is put forward after will stretch one's legs with overhead traveling crane and destroy, there is drawback in this method: stretch one's legs itself firm and
Infusibility, overhead traveling crane is difficult to thoroughly process；Processing the process time stretched one's legs longer, labor workload is big, and
Cause substantial amounts of thermal loss；Artificial treatment weak effect, after process, a period of time stretches one's legs and can be the longest
Greatly, the problem of stretching one's legs cannot be effected a radical cure.
Insulation material composition of extremely going up used by existing electrolysis bath is mainly electrolyte 70% and aluminium oxide 30% mixes
Thing, or pure alumina.Electrolyte and alumina mixture heat insulation effect are relatively big by particle size influences, insulation
Effect is relatively poor.Pure alumina easily sinks to anode bottom, forms precipitation, and after crusting in corner,
Forming hard old shell, heat insulation effect reduces.
Therefore, eliminate insulation material and the removing method stretched one's legs in aluminium cell corner at present, still have much room for improvement.
[summary of the invention]
It is an object of the present invention to propose a kind of heat conductivity little, it is possible to the elimination aluminum of exothermic oxidation
The insulation material stretched one's legs in electrolysis bath corner, this insulation material has good heat insulation effect, it is possible to fill at anode scrap
Enter, electric conduction quantity hour provides heat for anode, shortens the anode non-conductive time, increases anode conducting amount,
Promote the fast melt stretched one's legs in corner.
Another object of the present invention is to propose one utilizes described insulation material elimination aluminium cell corner to stretch
The removing method of lower limb, the method can quickly eliminate corner and stretch one's legs；Uniformly anode electrolytic cell CURRENT DISTRIBUTION,
Improve current efficiency；Reduce the potential safety hazard that anode bending hoisting mechanism brings；Reduce corner to stretch one's legs greatly
The primary aluminum abnormal quality caused, improves primary aluminum quality.
For achieving the above object, the present invention provides a kind of aluminium cell corner that eliminates to stretch one's legs in one aspect
Insulation material, described insulation material by weight percentage, consists of composition:
Aluminium oxide 60-90%
Aluminum 5-30%
Electrolyte 5-20%
Wherein, the thickness of described insulation material is 20-30CM.
Preferably, the described insulation material proportion below granularity 3mm is 80-90%, granularity 3-8mm
Described insulation material proportion be 10-20%.
The present invention provides a kind of on the other hand and utilizes described insulation material to eliminate what stretched one's legs in aluminium cell corner
Removing method, described method includes:
A, stretching one's legs aluminium cell corner carries out an artificial treatment, is stretched one's legs in corner and all destroys；
B, the position stretched one's legs in the corner being struck off load hot anode scrap；
C, behind the big face of hot anode scrap and end face crust, carry out receiving limit by described insulation material diagonal section；
After d, receipts limit complete, described insulation material is added a cover one layer of heat preservation cotton；
After e, electrolysis bath run 5-10 days, repeat a-d；
After f, electrolysis bath run 10-15 days, repeat a-d.

Wherein, the thickness of described insulation material is 20-30CM.
The inventors found that the insulation material composition used by traditional electrolyte groove is mainly electrolyte 70%
With the mixture of aluminium oxide 30%, or pure alumina, there is electrolyte and alumina mixture insulation
Effect is relatively big by particle size influences, and heat insulation effect is relatively poor；Pure alumina easily sinks to anode bottom, shape
Become precipitation and after crusting in corner, form hard old shell, reduce the problems such as heat insulation effect.Therefore,
There is no the most at present and can effectively eliminate the insulation material stretched one's legs in aluminium cell corner.The present inventor is in surprise
Find, by the insulation material formula of the present invention, be provided that a kind of heat conductivity is little, it is possible to exothermic oxidation
Eliminate the insulation material stretched one's legs of aluminium cell corner, and successfully solve present in prior art such as
Above-mentioned technical problem, it is achieved good heat insulation effect, it is possible to load at anode scrap, electric conduction quantity hour is
Anode provides heat, shortens the anode non-conductive time, increases anode conducting amount, and it is quick that promotion is stretched one's legs
Melt.
