Based on Gaussian meter measurement and simulation calculation, the spatical magnetic field distribution outside aluminum reduction pot was studied, and the simulation and measurement results were compared to verify the accuracy and reliability of the calculation model. The calculation ressult of the spatial magnetic field in the aluminum potroom shows that the magnetic field strength and gradient are relatively larger in areas closer to reduction pots and busbar, and vice versa. Based on the simulation calculation results, the corresponding technical requirements for anti-magnetic design are put forward for some important production and control equipment which operate in relevant areas of the potroom in the long term.
