  • Method and apparatus for smelting charge materials in electric arc furnace
    Patent number: 4388108
    Abstract: A method for smelting charge materials in an electric arc furnace consists in that a bath of the electric arc furnace is loaded with the charge materials, electrodes of the electric arc furnace are supplied with an alternating current, the charge materials are melted, redox reactions are conducted and a finished melt and a slag are tapped, the alternating current of industrial frequency supplied to the electrodes of the electric arc furnace being first converted to one of a frequency ranging between 0.05 and 30 Hz. An apparatus for carrying into effect the above method comprises an electric arc furnace, in a bath of which are inserted electrodes. A secondary winding of a transformer is coupled with the electrodes through power supply arrangements.
