The present invention concerns a method and a device for processing calcinated carbon bodies such as anodes or cathodes for use in connection with electrolytic production of aluminium. The carbon bodies are processed using a rotating processing tool (1) that consists of a mainly circular disc with cutting edges (12, 12') mounted at its periphery. The cutting edges may be made of polycrystalline diamond (PCD) or an equivalent material. With the present invention it is possible to create slots in calcinated carbon bodies in an efficient manner with low tool wear.
La présente invention concerne un procédé et un dispositif de traitement de corps carbonés calcinés tels que des anodes ou des cathodes, pouvant être utilisés conjointement avec la production électrolytique d'aluminium. Les corps carbonés sont traités à l'aide d'un outil de traitement rotatif (1) composé d'un disque principalement circulaire à bords tranchants (12, 12') disposés à sa périphérie. Les bords tranchants peuvent être constitués de diamant polycristallin (PCD) ou d'un matériau équivalent. Avec la présente invention, il est possible de créer des encoches dans des corps carbonés calcinés de façon efficace avec une faible usure d'outil.
