Abstract
An iron free self baking electrode comprises an outer metallic shell, a center core formed of a graphite or prebaked carbon material spaced from the shell and a quantity of a carbonaceous paste which cures into a solid electrode and bonds to the graphite or prebaked carbon core as the core and paste passes downwardly through the casing. The graphite or prebaked carbon core conducts heat to the paste material to promote more rapid curing.
