Abstract
The invention relates to a method for connecting an anode guide rod and an anode steel claw, which is characterized in that the connection process of the method comprises the following steps: (1), respectively welding aluminum surfaces of aluminum-steel explosion composite soldering terminals at eudipleural positions at the lower part of the anode guide rod; and (2), arranging a concave groove on a boss of the anode steel claw, embedding the lower part of an aluminum guide rod, at which the welding terminals are welded well, into the concave groove of the boss of the steel claw, and welding the edges of the soldering terminals, which are in contact with the concave groove of the boss of the steel claw, wherein the width of the concave groove is the sum of the width of the cross section of a guide rod of the anode guide rod and the thicknesses of two aluminum-steel explosion composite soldering terminals. The method provided by the invention is applicable to the connection of the anode guide rod and the anode steel claw applied on all prebaked aluminum electrolytic cells; the contact voltage drop of aluminum-iron can be decreased greatly; the connection strength of the aluminum-iron is further enhanced synchronously; and the economic benefit of an aluminum electrolysis factory is improved.
Description
Technical field
The present invention relates to the method for attachment of a kind of anode rod and anode steel jaw.
Background technology
In the pre-calcining electrolytic cell production process, the connection between anode rod and the anode steel jaw is very important, should have less resistance stronger strength of joint is arranged again.Aluminum current guide rod and anode steel jaw generally are employed between aluminium guide bar and the anode steel jaw boss with an aluminium-steel compound weld tabs that explodes and connect; Mode of connection is welding, weld seam be aluminium guide bar with aluminium-steel explode that compound weld tabs contacts all around and aluminium-steel explode that compound weld tabs contacts with steel pawl boss around.Owing to mainly lean on this eight weld seams completion being connected between guide rod and the steel pawl; Therefore aluminium-iron contact drop is not ideal, is generally about 10mV, separately this piece ton aluminum consumption 30kWh; Strength of joint is also not ideal, and the situation that has anode and aluminium guide bar to break away from the time of in process of production occurs.
Patent 200510017656.5 invention anode production technology of steel aluminium conical surface press joining method, feasible on this Technology, but implementing process is complicated; Patent 200810229268.7 has been invented the syndeton of anode rod and anode steel jaw; This patent is built guide rod and steel pawl contact surface with the phosphorus pig iron; Connect through a bearing pin between guide rod and the steel pawl simultaneously, this method medium phosphoric iron is big inadequately to the sticking power of aluminium and steel, and the intensity of bearing pin is also big inadequately; Therefore strength of joint can not satisfy application request, and implementing process is complicated.
Summary of the invention
The object of the invention is exactly the deficiency that exists to above-mentioned prior art, provides a kind of anode rod that can effectively solve to be connected anode and the anode rod of the easy disengaging problem of aluminium guide bar and the method for attachment of anode steel jaw in ferro-aluminum contact drop height, the production with anode steel jaw.
The objective of the invention is to realize through following technical scheme.
The method of attachment of a kind of anode rod and anode steel jaw is characterized in that the step of its connection process comprises:
(1) in symmetrical position, anode rod bottom respectively with aluminium-steel explode compound weld tabs and the aluminium face weld;
(2) boss of anode steel jaw is left a Baltimore groove; The Baltimore groove width is guide rod transverse section width and two aluminium-steel of anode rod compound weld tabs thickness sums of exploding; The aluminium guide bar bottom of having welded weld tabs is embedded in the recessed table groove of steel pawl boss, weld tabs and steel pawl boss grooves contact edge are welded.
The method of attachment of a kind of anode rod of the present invention and anode steel jaw aluminium guide bar and anode steel jaw are increased to 14 through the explode weld seam of compound weld tabs of aluminium-steel by original eight, and being connected of steel pawl and aluminium guide bar has also increased by eight welds.Not only significantly reduced aluminium-iron contact drop, can be reduced in the 3mV from 10mV, ton aluminium 21 kWh that economize on electricity, and increased the strength of joint between steel pawl and the guide rod, significantly reduce the generation of anode and aluminium guide bar disengaging.
Method of the present invention is applicable to being connected of the anode rod used on all pre-calcining electrolytic cells and anode steel jaw, can significantly reduce aluminium-iron contact drop, has also strengthened the strength of joint of aluminium-iron simultaneously, has reduced the economic benefit that has improved aluminum electrolysis.
Embodiment
The method of attachment of a kind of anode rod and anode steel jaw, connection process are that the right and left respectively welds an aluminium-steel compound weld tabs that explodes in the anode rod bottom, and the aluminium face of weld tabs is towards aluminium guide bar; The boss of anode steel jaw is designed to the Baltimore groove with anode rod and two compound weld tabs thickness sums; To weld the explode guide rod of compound weld tabs of aluminium-steel and embed in the Baltimore groove of steel pawl boss, the outer, contact site of steel pawl boss and compound weld tabs welded, thereby accomplish being connected of anode rod and steel pawl.
The method of attachment of a kind of anode rod of the present invention and anode steel jaw, its used raw material and existing guide rod with being connected of steel pawl used material consistent, need not to purchase separately, the groove on the anode steel jaw boss only needs do slightly to transform and can accomplish foundry pattern.Though this mode of connection has increased welding job, explained that also welding quality and welding strength have significantly raising than original mode of connection, thereby significantly reduced the aluminium-iron contact drop between guide rod and the steel pawl and significantly improved their strength of joint.
Embodiment
The explode aluminium face of compound weld tabs of aluminium-steel is welded on symmetrical position, anode rod bottom respectively, forms weld seam; The anode steel jaw boss is cast as a groove shapes; Recess width is guide rod transverse section width and two aluminium-steel of anode rod compound weld tabs thickness sums of exploding; The aluminium guide bar bottom of having welded weld tabs is embedded in the groove of steel pawl boss; Aluminium-steel is exploded compound weld tabs and steel pawl boss contact edge along welding, and weld seam is finally to form 14 weld seams.
Claims (1)
1. the method for attachment of anode rod and anode steel jaw is characterized in that the step of its connection process comprises:
