First, carefully select the aluminum anode assembly, and select the aluminum anode assembly that do not have defects such as explosive welding ingot cracking, steel claw cracking, rotten claws, and falling claws. The steel claws are first dedusted, and then put into the pickling tank. Carry out pickling treatment, and then straighten the aluminum guide rod on the press, so that the straightness of the aluminum guide rod reaches 1/1000, and the projection error reaches the requirement of 3/1000. Finally, polish the head of the steel claw and the crimping surface of the aluminum guide rod with the anode bus bar until the metal luster is exposed. The aluminum anode assembly after the above treatment can be put into electrolysis production and use.
Saw off the explosive solder nugget
First set up a sewing machine to saw off the explosive welding block from the aluminum anode assembly. After sawing, carefully check the end face of the aluminum guide rod and the end face of the steel claw. If there are more pores, you can cut off more as appropriate, but you must ensure the use of the aluminum anode assembly. length.
Repair and Treatment of Shallow Cracked Steel Claw
For steel claws with shallow cracks, we only plan a "V" groove of no more than 60° at the crack, remove dirt and rust in the grooves, and repair them to the original shape of the steel claws with carbon dioxide gas shielded welding.
