Description
Technical field
The present invention relates to a kind of aluminium electrolysis anode steel pawl technical field, especially a kind of novel note copper aluminium electrolysis anode steel
Pawl.
Background technique
Modern aluminium electrolytic industry generallys use prebaked anode and produces for aluminium electrolytic industry.It is set in anode carbon block upper surface
Having 2-4 diameter is 160-180mm, and depth is the circular groove of 80-110mm, is commonly called as charcoal bowl, and in anode assembling, charcoal bowl is used to install sun
Pole pawl foot, and cast in anode claw foot in charcoal bowl with the phosphorus pig iron, anode claw top and aluminium conducting rod are connected by aluminum steel explosion weldering
It connects, connect aluminium conducting rod closely with anode carbon block, form anode carbon block group.
Existing anode steel claw is all formed by molten steel is integrated poured, and is solid construction.It (is connect with explosion piece by steel pawl head
Part), steel pawl crossbeam and 2-8 steel pawl foot constitute, steel pawl foot is solid cylinder, and resistivity is higher, and electric current is caused to waste
It is excessive.
In electrolysis production, in order to reduce the waste of anode anode scrap, it is necessary to it is as far as possible that anode anode scrap burning is thin, when residual altitude is
When 15-18mm, it is necessary to change poles.The depth that general carbon block immerses electrolyte is 150mm, in anode carbon block service life latter stage, sun
For the thickness of pole carbon block in 180mm or less, the top surface of anode carbon block is very close to electrolyte level face, and anode steel claw is close to anode
The part of carbon block is easy to deform because temperature is excessively high, scaling loss.By magnetic field and airflow influence, bath surface constantly has strong liquid
State electrolyte wave generates, and in the actual production process, anode joint is often corroded by electrolyte, and the ferro element of anode joint dissolves in
In electrolyte, enters aluminium ingot immediately, influence quality of finished；It will also result in anode steel claw ablation, deformation because temperature is excessively high simultaneously, make
At the general service life of anode joint at 3 years or so, this also increase accordingly production cost, and in anode carbon block end of lifetime,
It is extremely conductive uneven necessarily to bring charcoal, and then leads to electrolytic cell fluctuation of operating conditions for excessively thin anode anode scrap thickness, and power consumption increases.
In a series of hollow note aluminium formula steel pawls applied before the present invention, such as the present inventor's application 201910324977.1
Anode steel claw in patent uses steel shell, aluminium core structure, especially steel pawl foot and crossbeam and has been all made of steel shell aluminium core structure,
But it is had the following problems in subsequent actual production:
1, for hollow note aluminium formula steel pawl when being used on electrolytic cell, under 920-950 DEG C of electrolytic cell of high temperature action, because
Fusing point for aluminium is 660 DEG C, so the aluminium core on steel shell in the end of steel pawl underfooting melts, the aluminum water after fusing is to steel shell material
Material has certain solution ration, has seriously affected the service life of steel pawl.
2, since the aluminum water after fusing is having certain solution ration to steel shell material, the elements such as iron in steel shell material by
Gradually be dissolved in aluminum water, at 740 DEG C saturated concentration of the iron in aluminium up at 8.12%, 900 DEG C up to 16%, iron content 8%-16%
Ferroaluminium, resistivity is up to 7-16 × 10-4Europe mother/m, and the resistivity of fine aluminium is only 2.83 × 10-8Europe mother/m, aluminum water
In dissolved steel shell material after resistance also increase accordingly, cause electric energy loss to increase.
In conclusion in the prior art for aluminium electrolytic industry, a series of hollow note aluminium formulas applied before the present invention
In steel pawl, such as the present inventor applies for the anode steel claw in 201910324977.1 patents, and there are following technical problems for patent: steel
Aluminium core in shell melts under electrolytic cell high temperature action, and the aluminum water after fusing is having certain corrosion energy to steel shell material
Power has seriously affected the service life of steel pawl, and resistance also increases accordingly after steel shell material has been dissolved in aluminum water, causes electric energy loss
Increase.
Summary of the invention
The object of the present invention is to provide a kind of Novel hollows to infuse copper anode steel claw for aluminum electrolysis.The present invention passes through to sun
Structure, material and the production method of pole steel pawl are transformed, and are applied to aluminium cell, and extend anode steel claw uses the longevity
Life；Reduce the resistivity of anode rod, steel pawl；Reduce electricity damage, save the cost.
Technical solution of the present invention: a kind of Novel hollow note copper anode steel claw for aluminum electrolysis includes steel shell, sets on steel shell
