New anode steel claws for electrolytic aluminum

May 22, 2023

Anode steel claws is an important component of pre-baked anode in aluminum electrolysis production. Its main function is to connect anode carbon blocks and transmit current to the electrolytic cell.The electrical conductivity and service life of electrolytic aluminum greatly affect the electricity consumption and economic benefits.At present, anode steel claws are made of scrap steel and produced by lost mold casting.Easy to produce chemical composition instability, high resistivity, poor oxidation resistance and other defects.

The material of the new anode steel claws is low carbon steel, the anode steel claws beam is made of hot rolled thick plate, the anode steel claws beam is cut according to the size of the anode steel claws beam, the steel anode claws leg is made of rolled round rod, the steel anode claws leg is welded with the steel anode claws beam by special fusion welding technology to realize the metallurgical combination of full section.The application results in domestic electrolytic aluminum enterprises show that the new anode steel claws has higher conductivity and oxidation resistance than the ordinary cast steel claws, which can better meet the requirements of electrolytic aluminum production.
