Abstract
A composite electric arc furnace electrode comprises a heavy-walled tubular graphite body with a sealed inner bore, a hollow nipple, a central coolant supply pipe, and a metal header assembly. If the unit fails, it is disassembled, a new graphite main tube assembled with the metal parts, and the graphite tube consumed in the normal fashion as a tip electrode.
