Abstract Scope |
Electrolytic production of aluminium has changed tremendously over the last 50 years, and this is no exception to cathode materials and designs. Over this period the lifetime of cathodes has doubled from an average lifetime of around 1000 days; this being a testimony for the many scientific developments since then. The presentation will cover some of the major developments in cathodes over the decades and the implications these have had on modern aluminium production. Major changes in cell arrangement and cell dimensions as well as composition of carbon cathode and refractory materials are only some of the many developments that have been implemented. Also, the compensation of the magnetohydrodynamic forces created by the amperage increase from large cells around 150-200 kA 50 years ago to modern cells reaching 600 kA have been important for maintaining long lasting cathodes. |
