[0002] The anode steel claw is an important connecting structure between the guide rod and the carbon block in the electrolytic aluminum anode. On the one hand, the anode steel claw needs to withstand the strong current passed into the electrolytic cell during the aluminum electrolysis production process. The average current passing through each steel claw is about 8333A (single anode), so the anode steel claw has good conductivity; on the other hand, the anode steel claw connects the aluminum guide rod and clamps the anode carbon block. Since each new anode weighs about 1000kg, the anode steel claw needs to have a certain strength and stability.
[0003] At present, the quality of anode steel claws of electrolytic aluminum enterprises has inherent defects. In terms of production raw materials, scrap steel, miscellaneous steel and scrapped steel claws are mostly used. The content of alloy elements in the steel claws fluctuates greatly, especially the content of impurity elements such as C, S, and P is too high, which will lead to increased resistance of the steel claws and reduced conductivity of the steel claws. In terms of production methods, the unreasonable casting process of the steel claws will lead to defects such as shrinkage cavities, shrinkage, and inclusions inside the steel claws, which will reduce the effective conductive area of the steel claws, increase the resistance of the steel claws, and reduce the conductivity of the steel claws.
