CA 2077669

A furnace configuration is disclosed which is suitable for scale-up of heat transfer limited processes performed at high temperatures, e.g: carbothenmic reduction of transition metal or rare earth oxides. The furnace is inductively heated by external insulated coils (3) and the susceptor (2), preferably graphite rings, is placed within the charge (1) away from the outer surfaces of the charge (1). Consequently heat is transferred to the charge (1) in three dimensions and the process approaches completion before the insulation (4) is subjected to high temperatures. As a result of this three dimensional heat transfer, larger furnaces are possible within the heat transfer constraints of these high temperature processes and higher yields are obtained.

On décrit un four adapté à l'agrandissement à l'échelle des processus à transfert thermique limité réalisés à des températures élevées, tels que la réduction carbo-thermique des oxydes d'éléments de transition ou des terres rares. Le four est chauffé à haute fréquence par des bobines isolées externes (3), et l'on place le suscepteur (2), de préférence des anneaux de graphite, à l'intérieur de la charge (1) et à distance des surfaces externes de celle-ci. En conséquence, la chaleur est transférée à la charge (1) de manière tridimensionnelle et le processus touche à sa fin avant que l'isolation (4) ne soit soumise à des températures élevées. Grâce à ce transfert de chaleur tridimensionnel, on peut réaliser des fours plus grands conformes aux limitations du transfert de chaleur de ces processus à température élevée, et l'on peut obtenir des rendements plus élevés.
