Cathode designs and the impact on cell performance

摘要

In the last decade, the aluminum industry has realized interesting achievements due to the cathode design.The combination of cathode shapes and collector bar designs allows for significant energy savings.On the basis of thermo-electric and magneto-hydrodynamic modeling work a number of designs are discussed.If some basic concepts are valid for all smelters, the optimum solution may significantly depend on the local cost structure.
