  • ELECTRIC ARC MELTING FACILITY AND METHOD FOR PRODUCING MOLTEN METAL BY USING THE ELECTRIC ARC MELTING FACILITY
    Publication number: 20120152057
    Abstract: An electric arc melting facility includes a melting chamber configured to melt a source iron therein by electric arc discharge generated from an electrode, and a source iron feeder configured to continuously feed the source iron to the melting chamber. The facility further includes a state change detector configured to detect a state change of the melting chamber when the electric arc discharge is generated from the electrode, and a controller configured to adjust a feed rate at which the source iron feeder feeds the source iron to the melting chamber, based on a detection result of the state change detectors.

  • Method for increasing the efficiency of a direct current electric arc furnace
    Patent number: 5189682
    Abstract: The invention provides a direct current electric arc furnace which is composed of a feeding system of direct current to the furnace, a movable electrode at the roof of the furnace, and a bottom electrode attached to the bottom of the furnace at the position deviated from the center of the bottom of the furnace, the deviated distance from the center being determined by a magnetic field, generated by a current in the steel bath of the furnace, from under an arc generated by the movable electrode to the bottom electrode, which can cancel a second magnetic field generated by the current of the feeding system.
