Description
Technical Field
The utility model relates to a conductive anode device used in aluminum electrolysis, which comprises an aluminum guide rod and an anode steel claw connected with the guide rod.
Background
The anode conducting device used in the electrolytic aluminium industry at present consists of an upper aluminium guide rod and an anode steel claw with a steel lower part, wherein the steel and the aluminium cannot be directly welded and are connected through an explosive welding block. The explosion welding block is made up by welding two different materials of steel and aluminium together by using explosion welding technique, when the anode conducting device is made up, the aluminium portion of explosion welding block is welded with upper aluminium guide rod portion of anode conducting device by means of argon arc welding, and the steel portion of explosion welding block is welded with lower anode steel claw beam flat steel of anode conducting device by means of gas shielded welding, and its connection mode is the content disclosed in attached figure 1 of Chinese patent application 2010100007746, and has no reinforcing device structure. The existing anode conducting device forms aluminum-aluminum welding, aluminum-steel explosion welding and steel-steel welding between the bottom of an aluminum guide rod and the top of an anode steel claw beam flat steel. In the prior art, except that the aluminum-steel explosion welding is full-section welding, the aluminum-aluminum welding and the steel-steel welding can only realize groove girth welding under the prior art. The cold state pressure drop test data of the bottom of the anode steel claw aluminum guide rod and the top of the steel claw beam which are manufactured by connecting explosion welding blocks in the prior art are as follows: the load current is 99.8A, the cold state voltage drop is 0.3Mv, the cold state resistance is 3.5u ohm, the voltage drop belongs to the reactive voltage in the production of the electrolytic aluminum, and the current efficiency is reduced.
On the other hand, in the aluminum electrolysis production process, the steel-aluminum joint of the explosion welding block bears the gravity load in the electrolysis operation and simultaneously conducts the large current in the electrolysis, but the shearing force is generated at the joint due to the difference of the expansion coefficients of the steel and the aluminum, so that the aluminum-steel welding surface is locally cracked, the stress and the conductive area are gradually reduced, the resistance and the voltage drop at the aluminum-steel welding surface are greatly increased, and the temperature rise at the corresponding position is improved. When the cracking failure area reaches the corresponding proportion, the aluminum-steel welding surface is broken under the weight action of the carbon block and the steel claw, or the aluminum-steel welding surface is burnt due to the heating caused by overlarge resistance, so that the failure is caused.
In order to overcome the defects of the prior art, a series of solutions are provided in the prior art, such as: chinese patent application 2010100007746 discloses a technical scheme for adding an aluminum steel connection reinforcing device between an aluminum guide rod and an anode steel claw of a transition block, which is based on the connection mode between the aluminum guide rod and the anode steel claw of the original design by adopting an aluminum steel composite sheet, the reinforcing device is arranged between the upper part of an anode steel claw beam and the aluminum guide rod, namely, a reinforcing connection plate and a stiffening plate are additionally arranged, and a clamping bolt for firmly reinforcing the connection plate. Although the reinforcing plate, the reinforcing connecting plate and the anode steel claw are connected in an all-steel manner in the technical scheme, the weight load of the reinforcing plate is still mainly borne by the explosive welding blocks due to the small welding area, so that the problems in the prior art still exist although the technical scheme is improved to a certain extent compared with the prior art. In practice, the structure of the stiffening plate and the reinforcing connecting plate is found, after obvious cracks are generated at the explosive welding blocks, the resistance at the aluminum-steel welding surface of the explosive welding blocks is increased, and partial current passing through the stiffening plate and the reinforcing connecting plate is increased, so that the reinforcing connecting plate generates high temperature and fusing phenomena, and is broken more rapidly.
Chinese patent 2013107301429 discloses a transition-free welding device and a welding method for an anode guide rod and an anode steel claw, which attempt to increase the conductive area, reduce the resistance, reduce the heat generation, and realize the electricity-saving effect by changing the welding connection mode of the anode guide rod and the anode steel claw, and simultaneously improve the connection strength between the anode guide rod and the anode steel claw, thereby prolonging the service life of the anode guide rod and the anode steel claw. Chinese patent application 2015105033237 discloses a technical solution for preparing anode steel claw by electroslag welding, which attempts to improve the service life by changing the welding mode between steel and aluminum.
The chinese patent applications 2009100208155, 2014106680846 and 2013106400179 are to achieve the connection between steel and aluminum by friction welding, and improve the mechanical properties of the steel-aluminum joint formed by explosive welding.
One of the failure modes of the existing anode conducting device is as follows: the steel-aluminum welding surface of the explosive welding block is cracked. Research and analysis show that the expansion coefficient of the aluminum is more than twice that of the steel due to the difference between the expansion coefficients of the steel and the aluminum. During normal electrolysis operation, the working temperature of the explosion welding block is about 300 ℃, aluminum and steel respectively generate different linear expansions at the temperature, but due to the existence of an aluminum-steel welding surface, the expansion of the aluminum is limited by the steel part of the explosion welding block, meanwhile, a shearing force is generated on the aluminum-steel welding surface, the combination of the shearing force and the action of the gravity of the device tears the structure, so that the aluminum-steel welding surface is locally cracked and fails, the conductive area and the capability of bearing the gravity load are reduced, and simultaneously, the resistance and the pressure drop at the aluminum-steel welding surface are increased, and the temperature rise is intensified. When the cracking failure area reaches a certain proportion, the aluminum-steel welding surface is broken under the weight action of the carbon block and the steel claw, or the aluminum-steel welding surface is directly burnt due to heating because of overlarge resistance. The steel-aluminum joint formed by explosive welding or friction welding in the prior art is subjected to the dual actions of electric conduction and bearing the gravity load of the anode steel claw and the carbon block due to the specific structure, so that the local cracking failure of the aluminum-steel welding surface is enlarged, and the service life of the explosive welding block is shortened.
