power savings potential
improvement in current stability
- Regular anode assemblies with a cast-iron connection between rod stub and carbon anode (STC connection) suffer from high electrical resistance due to solidification shrinkage of the iron.
- Hatch anode nails form a tight, conductive bridge across the shrinkage gap. This reduces the electrical resistance of the anode assembly, making it less dependent on temperature.
- Reduced power consumption (kwh/kg Al)
- Increased current efficiency(%) due to lower pot noise (unstable current)
- Anticipated longer stub life due to colder stubs from less ohmic heating
