Abstract
The invention provides an electric-arc furnace electrode assembly having electrode sections of improved structural integrity. A pair of carbonaceous electrode sections are held securely in end-to-end relationship by a pin threaded into a pair of sockets found in the respective ends of the electrode sections. Harmful stress concentrations which occur near the base of the socket are reduced by providing a novel base portion. This is achieved by incorporating a generous radius of curvature intermediate the lower-most socket thread and the base of the socket. All of the socket threads are engaged and a threaded portion of the pin extends beyond the lowermost socket thread without engaging the base of the socket.
