In response to the low detection accuracy of the electrode tip position and the complexity in the development process for submerged arc furnaces, this paper introduces a novel differential magnetic field array detection system. The system, by deploying a magnetic sensor array and utilizing differential signal processing technology, effectively eliminates environmental interference and system noise, enhancing the accuracy and reliability of electrode tip position detection. 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. This research offers new ideas and technical support for the detection and control of industrial parameters in submerged arc furnaces.
