Abstract:
A replaceable graphite electrode tip is detachably connected with the lower end of a metal tube, the upper end of which is rigidly connected to electrical conducting means for supporting the tube from a holder in an electric arc furnace. The tube is protected from the heat of the furnace by refractory material forming a sleeve extending upwardly around the tube from the graphite tip.
