Abstract

An electrode holder for arc furnace electrodes having a cooled metal shaft at least partially surrounded by a protective jacket of hollow cylinder configuration, generally moldings resistant to elevated temperatures. The protective jacket can surround and protect portions of the electrode holder positioned within the furnace or portions of the electrode holder in a zone engaged by clamping jaws. The protective jacket consists of individual moldings configured to provide generally ring shapes which may be put together to form rings, and coherently surrounding the metal shaft.
