Abstract
A method for protecting anode assemblies in an electrolytic cell from thermal shock is disclosed. The method generally involves applying a thermal insulating layer () to the anode () prior to preheating the anode assembly in a furnace, where the layer () protects the anode () from thermal shock during transfer from the preheat furnace to the electrolytic cell. In a preferred embodiment the anode () is attached to a castable plate () that is also protected from thermal shock by an insulating layer.
