Patent

CA 2425457

A method for rebaking and graphitizing pitch- impregnated carbon bodies in an encapsulated Castner- type lengthwise graphitization furnace in one step, and a furnace shell constructed of element modules for carrying out the method. The oxygen content in the interior of the furnace is kept below 4% by volume. The method is carried out under atmospheric pressure or at pressures which differ only slightly from the atmospheric pressure.

Une méthode pour recuire et graphitiser des produits de carbone imprégnés de goudron dans un four de graphitisation longitudinal de type Castner encapsulé, en une étape, et un four constitué d'éléments modulaires pour exécuter cette méthode. La teneur en oxygène dans le four est maintenue à moins de 4 % en volume. Cette méthode est exécutée à la pression atmosphérique ou à des pressions très légèrement différentes de la pression atmosphérique.
