The utility model discloses the life of anode steel claw landing leg can obviously improve more than 1 year, and need not change the maintenance weldment work flow of current anode steel claw landing leg, can change an anode steel claw leg strap next welding and other maintenance work volumes and reduce former material consumption by greatly reduced to help reducing the manufacturing cost of electrolytic aluminum enterprise, reduce the loss that black appliances were pressed, reduce ton aluminium power consumption, reduce CO2 and discharge.

Description

A kind of corrosion-resistant antioxidative aluminium cell anode steel pawl supporting leg
Technical field
This utility model relates to technical field of aluminum electrolysis, is specifically related to a kind of corrosion-resistant antioxidative aluminium cell anode steel pawl supporting leg.
Background technology
Modern aluminum industry produces and uses cryolite alumina molten salt electrolysis.Molten cryolitic is solvent, and aluminium oxide is as Aluminum Electrolysis Production solute, and using carbon body as anode, aluminum liquid is as negative electrode, after being passed through powerful unidirectional current, under the high temperature of 900 DEG C-1000 DEG C, the two poles of the earth in electrolysis bath is electrochemically reacted, is i.e. electrolysed.Carbon body anode i.e. anode carbon block is to be connected with the anode bus on electrolysis bath by anode steel claw and guide rod.In normal productive process, anode carbon block is constantly to consume, and has certain anode change cycle.Generally in the latter stage of anode change cycle, it may appear that high-temperature fusion electrolyte washes away the risk of anode steel claw supporting leg.
Currently used anode steel claw supporting leg is easy for attenuating due to constantly erosion and the high-temperature oxydation of electrolyte, when diameter becomes the 2/3 of original diameter, being accomplished by amputating the steel pawl supporting leg the most more renewed, current anode steel claw supporting leg service life is generally at about 1 year.In steel pawl supporting leg Renewal process, needing to beat groove and weld, bonding area is often below the diameter of mother metal, during causing use, soldering tip pressure drop is bigger than normal, adds the loss of black voltage in vain, simultaneously because bonding area is bigger, welding job amount is huge, and welding cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is to provide the corrosion-resistant antioxidative aluminium cell anode steel pawl supporting leg of a kind of low energy consumption, easy care, length in service life.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
Designing a kind of corrosion-resistant antioxidative aluminium cell anode steel pawl supporting leg, including steel pawl supporting leg blank, be covered with 1~3 layer of coat of metal on the surface of described steel pawl supporting leg blank, the described coat of metal is aluminium coat, copper coating or nickel coating.
Preferably, the described coat of metal is 3 layers, and it is followed successively by copper coating, aluminium coat, nickel coating from the inside to the outside, and its electric conductivity is more preferable, corrosion resistance is higher, and service life greatly extends.
Preferably, the thickness of the described coat of metal is 0.01~5mm.
Preferably, porosity≤5% of the described coat of metal.
Preferably, the bond strength > 50MPa between the described coat of metal and described steel pawl supporting leg blank.
Advantageous Effects of the present utility model is:
1. this utility model anode steel claw supporting leg compares with existing anode steel claw supporting leg, electrolyte-resistant corrosion and the coat of metal of resistance to high temperature oxidation is covered on the surface of steel pawl supporting leg blank, the coat of metal and mother metal bond strength >=50MPa, porosity≤5%, corrosion rate≤0.01mm/d in the high-temperature electrolysis matter melt liquid of 900 DEG C~1000 DEG C, under the hot environment of 900 DEG C, the oxidation rate≤0.01mm/d being exposed in air, it is corrosion-resistant, antioxygenic property is excellent.
2. can significantly improve more than 1 year the service life of this utility model anode steel claw supporting leg;And need not change the repair welds workflow of existing anode steel claw supporting leg;Can be substantially reduced and change the welding that brings of anode steel claw supporting leg and other maintenance workload and reduce raw materials consumption, and contribute to reducing the production cost of aluminium electrolysis enterprise, reduce the loss of black voltage, reduce ton aluminum power consumption, reduce CO2Discharge.
