Description

Technical Field

[0001] The utility model relates to the field of electrolytic aluminum, in particular to an anode steel claw full-section welding device. Background Art

[0002] After repeated use, the anode steel claws used by electrolytic aluminum enterprises have erosion, wear, and inward bending. The diameter of the steel claws gradually becomes thinner, which affects the use and increases the steel-carbon pressure drop. Such steel claws are unqualified anode steel claws and need to be replaced and repaired. For unqualified anode steel claws, the gas cutting method is used to separate the steel claws from the steel beam of the claw body, and then the sawn round steel of the same specification is replaced by welding to complete the replacement and repair of unqualified anode steel claws.

[0003] The traditional welding method can only achieve welding of the periphery of the anode steel claw and the main body of the steel claw head. The center of the anode steel claw cannot be welded, thus failing to achieve overall seamless welding. Its mechanical strength is low, and it mainly relies on the welds around it for conductivity. The current flowing through this area forms a bottleneck effect, causing intense heat and a large voltage drop, resulting in high power consumption in aluminum electrolysis.

[0004] Patent No. CN201510867586.6 discloses an automatic welding repair method for anode steel claw heads, which first welds the center position of the anode steel claw, and then welds by annular surfacing until the overall welding of the anode steel claw is completed, which effectively enhances the welding structural strength of the anode steel claw head; but this method is complicated to operate and time-consuming, which seriously reduces the repair efficiency of the anode steel claw; at the same time, there will inevitably be a certain welding gap in the annular surfacing process, which cannot make the welded anode steel claw achieve the best use effect; and, the existing welding work is usually completed on a workbench. Since the anode steel claw head is heavy, it is not easy to achieve the welding positioning operation between the anode steel claw head and the steel claw head body when there is a height difference between the welding position of the anode steel claw head and the steel claw head body, which seriously affects the welding efficiency of the anode steel claw, and it is necessary to improve it.
