摘要
A new electrode is joined to a consumed electrode of the electric furnace according to a method comprising the steps of lifting and transporting the new electrode suspended from a joining apparatus by a crane, aligning both electrodes by throwing a laser beam from a projector disposed to the crane on a positioning marker disposed on a deck plate provided in the vicinity of the electric furnace, screwing a screw thread of the new electrode into a threaded hole of the consumed electrode by actuating an electric motor disposed in the joining apparatus, and tightening both electrodes at desired tightening torque by operating the motor in a stalled state with a small electric current of low frequency.
