Description

Anti-deformation anode guide rod group Technical Field The application relates to the technical field of anode guide rod groups, in particular to an anti-deformation anode guide rod group. Background The anode of the aluminum electrolysis cell is one of important raw materials for producing electrolytic aluminum, and is used as a conductor for leading direct current to an electrolyte layer and also used as a carbon material for participating in anode reaction of electrolysis. In the prior art, the anode of the aluminum electrolysis cell consists of an anode guide rod group and an anode carbon block. The anode guide rod group mainly comprises an anode guide rod, an anode steel claw and a steel-aluminum connecting structure for welding the anode guide rod and the anode steel claw together. The anode steel claw comprises a beam and a claw part. At present, the steel-aluminum connecting structure is usually a steel-aluminum explosion welding block, and the anode guide rod and the cross beam of the anode steel claw are welded together in a steel-aluminum explosion welding block transition welding mode. Claw parts of the anode steel claw are cast in a carbon bowl of the anode carbon block through phosphorus pig iron. In the production process of electrolytic aluminum, the anode steel claw of the aluminum electrolysis cell is conductive and can be heated to expand, and the anode carbon block is heated and also can be expanded. Because the claw part of the anode steel claw is cast in the carbon bowl of the anode carbon block, and the thermal expansion coefficient of the anode carbon block is smaller than that of the anode steel claw, the expansion length of the cross beam of the anode steel claw is larger than that of the anode carbon block, so that the cross beam of the anode steel claw is arched upwards, and the claw part of the anode steel claw is bent inwards. As the number of cycles of use of the anode steel stud increases, anode steel stud deformation is gradually exacerbated. According to the related data, after a period of annual production in a certain factory, the repair quantity of the anode guide rod set reaches 2000 sets/month, the deformation and damage rate of the anode steel claw reaches 55%, and the service life of the anode guide rod set is seriously shortened. Disclosure of utility model The application provides an anti-deformation anode guide rod group, which solves the technical problems of easy deformation and short service life of the anode guide rod group in the prior art. The application provides an anti-deformation anode guide rod set, which adopts the following technical scheme: The anti-deformation anode guide rod group comprises an anode steel claw, a steel-aluminum connecting piece and an anode guide rod, wherein the steel-aluminum connecting piece is used for connecting the anode steel claw with the anode guide rod, the anode steel claw comprises a cross beam and a claw part, the steel-aluminum connecting piece comprises a plurality of steel-aluminum composite sheets which are arranged in a laminated and compact manner, each steel-aluminum composite sheet comprises steel sheets and aluminum sheets which are tightly combined together, each steel-aluminum connecting piece is provided with an aluminum welding surface welded with the side surface of the anode guide rod and a steel welding surface welded with the upper surface of the cross beam, the side surface of each steel sheet, which is used for being welded with the cross beam, forms the steel welding surface, and the cross beam is provided with a deformation joint for expansion deformation of the cross beam. The anode guide rod group has the advantages that in the first aspect, the deformation joint can provide a certain stress deformation space for the cross beam when the cross beam is subjected to conductive heating expansion, so that the deformation stress of the cross beam is reduced, the deformation of the anode guide rod group is reduced, and the service life of the anode guide rod group is prolonged. In the second aspect, the steel-aluminum connecting piece comprises a plurality of steel-aluminum composite sheets which are arranged in a laminated and compact manner, when the steel-aluminum composite sheets are used for welding the anode guide rod and the anode steel claw, the steel-aluminum connecting piece, the anode guide rod and the anode steel claw can have larger welding areas, so that the actual contact area of the anode guide rod and the anode steel claw is increased, the pressure drop between the anode guide rod and the anode steel claw can be reduced, and the connection strength of the anode guide rod and the anode steel claw can be improved. Optionally, two steel-aluminum connecting pieces are provided, and the two steel-aluminum connecting pieces are respectively located at two opposite sides of the anode rod, and the deformation joint is located at a position between the two steel-aluminum connecting pieces on the
