Abstract

Cette invention concerne un procédé de production de carbure de calcium à partir d'un mélange de base se composant de chaux et d'une matériau contenant du carbone, lequel procédé consiste à soumettre le mélange à un traitement électrothermique à l'aide d'électrodes. La nouveauté de ce procédé tient au fait que le mélange se présente comme une couche ininterrompue circulant sur un transporteur de type fermé, lequel transporteur se compose de sections de type goulottes assemblées les unes avec les autres par des charnières. La couche de mélange de base est densifiée jusqu'à ce que l'on obtienne la structure la plus homogène possible, puis soumise à un processus de chauffage en trois étapes, au moins, à l'aide d'un groupe d'électrodes cylindriques rotatives horizontales (5, 6, 7). Ces électrodes entrent en contact sans glissement avec la surface de la couche du mélange de base, tandis que la tension appliquée auxdites électrodes (5, 6, 7) diminue d'étape en étape. Lors de la première étape, le chauffage se fait à une température allant de 800 à 1000 DEG C afin d'éliminer la vapeur et les particules volatiles. Lors de la deuxième étape, le chauffage se poursuit à une température s'approchant au maximum de la température à laquelle le carbure commence à se former. Lors de la troisième étape, enfin, le chauffage se fait à la température de formation du carbure, laquelle température est maintenue pendant un certain temps. On procède ensuite au refroidissement naturel du carbure de calcium ainsi obtenu lors de son acheminement à l'aide du transporteur (1) vers une zone de concassage.
