  • 2 Citations


Over the last twenty years, modeling of the Hall-Heroult cell has given researchers an enhanced understanding of the physical laws which govern this time-honored unit’s operation. Such knowledge has led directly to important gains in productivity through higher cell amperage, increased current efficiency, improved energy utilization and longer cell life. Mathematical and physical models will continue to be key elements to further gains in reduction process technology.
