PURPOSE:To heat a wire rod efficiently without causing damage thereof, by arranging electrodes contg. molten metal of low m.p. for electricity conduction heating on transporting line of wire rod at a necessary interval, and conducting electricity to the wire rod during transportation through the electrodes. CONSTITUTION:At least a pair of the electrodes 1, 1' for electricity conduction heating are arranged on linear transporting line of the wire rod 2 at a necessary interval to heat continuously the rod 2 during transportation. IN this method, the molten metal 3 of low m.p. contained in a molten metal bath vessel 4 is heated by a heat source 5, and used in molten state as electrodes 1, 1'. Which are connected to a power source 6, to conduct electricity to the material 2 therethrough. Thereby, the rod 2 is heated continuously without causing arc flaw, scratch flaw therein, efficiently and without arc generation with high voltage, high transporting velocity due to low contact resistance. |
