dc.description.abstract | The lifetime of an aluminum electrolysis cell is mainly determined by the cathode wear, especially for high amperage cells utilizing graphitized carbon cathodes. The cathode wear mechanisms are, however, complex and still subject to debate. Laboratory tests using inverted cell configurations have previously been used to study commercial cathode materials. Here we report on results obtained in the last 5 years for three different commercial cathode materials. The current density applied in the tests was in the range from 0 to 2 A/cm2 and the rotation speed of the cathode was from 0 to 125 rpm, corresponding to surface velocity 0-19.6 cm/s. The wear mechanisms with respect to current density, limiting current of Al4C3 formation and mass transport are discussed. In addition, similarities and differences between wear observed in the laboratory and in industry cells are discussed. | nb_NO |
