Latest Patents

Nusslin holds a pivotal patent titled "Arrangement for controlling the electrodes of an arc furnace." This invention introduces an impedance controller designed to regulate electrode-to-bath spacing in arc furnaces. The controller processes measurements related to electrode voltage and current, forming an actual impedance value through a divider. By comparing this value against a predetermined desired impedance, it generates a control signal. In cases of short circuits, if the actual impedance dips to a set lower limit, the controller's signal prompts full drive, allowing the electrodes to ascend at maximum speed. Furthermore, if the sum of the measurement quantities equates to zero, the controller’s output is effectively disabled, ensuring safety and efficiency.
