Abstract: PURPOSE: To provide a graphite nipple suitable for connection of a graphite electrode by containing mesophase pitch carbon fibers in a nipple extrusion blend, extruding the blend, and baking it at the specified temperature for graphitizing. CONSTITUTION: Carbon fibers manufactured from mesophase pitch having a melting point of less than 350 deg.C are mixed with cokes and a binder, a mixture is extruded to firm an extruded blend. The extruded blend is extruded to form a carbon nipple. The carbon nipple is baked at a temperature exceeding about 538 deg.C for sufficient time, then the baked carbon nipple is heated at a temperature exceeding about 2704 deg.C for graphitization. A graphite nipple suitable for connection of a graphite electrode is obtained.
