• Resumen

  • The Hall-Héroult process is a proven method for aluminium production and the technology is well understood. This short technical note describes some of the basic metallurgy associated with the steel cathode collector bar and how it is possible to reengineer this basic steel component to reduce energy consumption and generate some significant cost savings for the aluminium smelter operation
