Transition insert bimetallic plate for anode rod assemblies

Aug 17, 2022

Transition insert bimetallic plate for anode rod assemblies are often used in electrolytic aluminum plants. In order to reduce the loss of intermetallic compounds and heat in the bonding area, one method is to preferentially use a weld with a flat interface without melting; the other method is to provide a barrier at the interface to prevent diffusion. For example, Transition insert bimetallic plate for anode rod assemblies with a 2 mm titanium intermediate layer can withstand higher temperatures than a direct aluminum-steel joint. Including processing (480 ° C to 315 ° C) and use (425 ° C to 260 ° C).

Transition insert bimetallic plate for anode rod assemblies are often subjected to high temperatures and long periods of time during use (for example, they are used as anodes and cathodes in electrolytic melting plants). Under these conditions, FeAl3 and Fe3Al5 type intermetallic compounds are generated at the aluminum-steel interface during welding, which will reduce their bonding strength. For this reason, using titanium as an intermediate layer can reduce intermediate compounds at its interface and increase the strength of the welded joint. When working at 400 ℃ for a long time, the aluminum-titanium-steel transition insert bimetallic plate for anode rod assemblies still have reliable stability for a long time. When the aluminum-titanium-steel transition insert bimetallic plate for anode rod assemblies manufactured by is used, its bonding strength and electrical conductivity can remain unchanged when the use temperature reaches 450 ° C.
