  • Arc furnace control system
    Patent number: 4029888
    Abstract: An electric arc furnace control system is provided for positioning the furnace electrodes in accordance with the resistance of the arc. This is accomplished by balancing the arc current signal against a voltage signal multiplied by a signal representing the arc circuit power factor to provide an error signal. An analog command signal is then derived from the error signal to control the direction and speed of the electrode hoist drive motor.
