The study initially constructs a magnetic field detection model for the submerged arc furnace and analyzes the external magnetic field distribution based on the Biot-Savart law. The effectiveness of the differential magnetic field array detection method is validated by simulations. Test results indicate that the system can accurately detect the electrode tip position in harsh industrial environments, providing strong support for the efficient operation of submerged arc furnaces.
