    Abstract: A cover (3) for a furnace body (2) is connected to each of two upper electrodes (16, 17) which extend through the portions of the furnace cover (3) which are spaced horizontally from each other by a predetermined distance. The upper electrodes (16, 17) have upper conductors (20, 21) thereon, which extend in the directions in which the conductors (20, 21) are away from the other upper electrodes. Two lower conductors (22, 23) are provided so as to be connected to a lower electrode (1) and extend in the same direction as the upper conductors (20, 21). Separate power source circuits (24, 25) are provided between the extended ends of one set of upper and lower conductors (20, 22) and between those of the other set of upper and lower conductors (21, 23), and arcs (12a, 12b) occurring between the upper and lower electrodes (16, 1; 17, 1) are directed toward the center of the furnace body (2).
