Abstract
A method is provided for retrofitting conventional aluminum smelting cells with inert anode assemblies which replace the consumable carbon anodes of the cell. The inert anode assemblies are pre-heated prior to introduction into the operating cell. Insulation may be installed for reducing heat loss during operation of the retrofit cells.
