Title
(EN) METHOD AND ARRANGEMENT FOR PROCESSING CARBON BODIES
(FR) PROCÉDÉ ET AGENCEMENT POUR TRAITER DES CORPS DE CARBONE
Abstract
(EN)
The present invention concerns a method and an arrangement 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 (101) that consists of a mainly circular disc with cutting edges (114) mounted at its periphery. The cutting edges may be made of polycrystalline diamond (PCD) or an equivalent material. The rotating processing tool mounted on a rotating, driven spindle and is guided by guiding elements (110) that can be jets or perforated discs that blows pressurized air at the tool, or rollers (120). With the present invention it is possible to create narrow and deep slots in calcinated carbon bodies in an efficient manner with low tool wear.

La présente invention porte sur un procédé et sur un agencement pour traiter des corps de carbone calcinés, tels que des anodes ou des cathodes, pour l'utilisation en association avec la production électrolytique d'aluminium. Les corps de carbone sont traités à l'aide d'un outil de traitement rotatif (101) qui est constitué par un disque principalement circulaire, des bords coupants (114) étant montés à sa périphérie. Les bords coupants peuvent être faits de diamant polycristallin (DPC) ou d'un matériau équivalent. L'outil de traitement rotatif est monté sur un arbre rotatif entraîné et guidé par des éléments de guidage (110), qui peuvent être des jets ou des disques perforés qui soufflent de l'air comprimé au niveau de l'outil, ou des rouleaux (120). Grâce à la présente invention, il est possible de créer des fentes étroites et profondes dans des corps de carbone calcinés d'une manière efficace avec une faible usure d'outil.
