In view of the existing aluminum overcapacity and lower aluminum price in China, many companies took measures to reduce the production cost and the energy consumption, but there has been no normalized theory and method defined as yet.To address these issues, this paper puts forward the evident effects of energy-saving and current efficiency improvement in aluminum reduction cells using new thermal insulation pot lining design, application of optimal cathode structure and reduction of horizontal current device. A proper application of new lining materials and combination of relevant process parameters based on the finite element software ANSYS® and thermal field simulation software as the calculation method combining the actual production data are also used. Practice proves that the above-mentioned method combining design, simulation and experiment can become the effective and feasible way to achieve low energy consumption, low cost and high profit.
