The method and procedure for measuring the magnetic field of the aluminum reduction cell at low temperature and the principle of calculating the magnetic field of the aluminum reduction cell by the surface magnetic charge method are described. The technology of the technology and the calculation software are used to simulate the 160kA large prebaked anode aluminum reduction cell The magnetic field was measured and calculated. The actual measurement results show that it is more accurate to measure the magnetic field in the electrolyzer under the condition of low temperature, the method is simple and easy to operate, and the data stability is better. The measured magnetic field data at low temperature is in good agreement with the actual calculation. Compared with the magnetic field measurement and calculation methods in the United States, the low-temperature magnetic field measurement technology and the special calculation software for the magnetic field of the aluminum reduction cell developed according to the surface magnetic charge method are advanced
