  • Electrode positioning control
    Patent number: 4349912
    Abstract: An electrode positioning control for electric arc furnaces includes a first circuit for producing an electric error signal functionally related in magnitude and sense to the electrical parameters in the electrode. The error signal is used to control the firing angle of an electronic switching device coupled between an electrode positioning motor and its power source. In addition, a signal generator is coupled to the motor for providing a velocity feedback signal functionally related to motor speed and direction for further modulating the firing angle.
