Description
Technical field
The present invention relates to technical field of aluminum electrolysis, relate to a kind of anode steel claw for aluminum electrolysis specifically.
Background technology
Anode steel jaw plays the electric action formed a connecting link in the anode system of aluminium point solution groove, the material of current anode steel jaw is Normal Steel Casting, the working temperature of the anode steel jaw leg bottom of Normal Steel Casting material is 400 ~ 900 DEG C, very easy oxidative exfoliation, in use this position easily attenuates, the aluminium manufacturer's anode steel jaw leg oxidation rate had now is too fast, mainly because aluminum oxide powder and ionogen are trapped among around anode steel jaw leg, the iron generation electrochemical reaction of aluminum oxide and steel pawl leg in process of production, a life cycle 28-33 days surface energy oxidation 10mm-15mm, leg diameters reduces 20mm-30mm, within 1 year, use several times, just can not use when leg diameters reaches below 100mm.
Steel pawl is mainly used in passing through of anodic current, will the resistance of steel pawl leg be increased as steel pawl leg attenuates, and affects steel pawl energising efficiency, thus affects the power consumption efficiency of electrolytic tank electrolysis aluminium.Each aluminium manufacturer will not change 2---3 thousand groups not etc. every year, and not etc., expense is inconsiderable for each steel pawl 500-800 kilogram.Waste is large.
At present conventional method of redress is prescinded by the part steel pawl leg root attenuated, then do a steel pawl leg and be welded on original position and go, and between the larger 110-180mm of welded section, welds one.Time is long, costly.The cross section docking that thickness is larger, the not weld penetration of steel pawl, can only weld first and second, and welding is many, and steel pawl is just done for, this mode remedy the production capacity not only reducing electrolysis of aluminum and the cost considerably increasing electrolysis of aluminum.
Summary of the invention
The present invention is in order to solve above-mentioned technical problem, there is provided a kind of electrolytic aluminum anode steel pawl, its anti-oxidant, anti-corrosion, high temperature resistant and long service life, even if after the steel cylinder of outside scraps, only need to change steel cylinder excision, decrease the labour intensity of workman.
The technical solution adopted in the present invention is: a kind of anode steel claw for aluminum electrolysis, comprise anode rod, with the crossbeam be connected bottom anode rod and the steel pawl leg be arranged on crossbeam, described steel pawl leg comprises internal steel pawl leg, is set in the steel cylinder of internal steel pawl leg outside and is arranged on internal steel pawl leg excircle top and boss for supporting steel cylinder, the pyramidal structure that described steel cylinder increases gradually in diameter from top to bottom, and the top of steel cylinder is welded with boss, bottom and internal steel pawl leg have a common bottom surface with transmission current.
Be cavity structure between described internal steel pawl leg and steel cylinder.
Described crossbeam is connected with the ferrophosphorus being provided with cast between anode rod.
The outside surface of described steel cylinder is provided with decorative pattern.
Described steel cylinder trypsin method has one deck Al
2o
3protective coating.
Described crossbeam is rectangle or trapezoidal.
Be welded with between described crossbeam and anode rod and conduct electricity reinforced company's fishplate bar.
Beneficial effect of the present invention: the present invention is provided with steel cylinder and boss, after steel cylinder wearing and tearing only need cutting to carry out replacing, not only ensure that welding quality but also effectively reduce the labour intensity of workman, cavity is provided with between steel cylinder and internal steel pawl leg in the present invention, make under the prerequisite ensureing steel pawl leg energising section area, reduce the steel using amount of steel pawl leg, both ensure that energising effect in turn saves resource.
