Abstract

Selon ce procédé, on travaille avec des briquettes de l'agent réducteur possédant un excédent de carbone de plus de 50 % en poids au regard de la réaction indiquée et qu'en plus de SiC, du charbon activé est formé à une température inférieure à 1600 degrés C dans les briquettes, à la partie supérieure du bas fourneau électrique, le quartz étant réduit dans la partie inférieure du bas fourneau à l'aide de ce charbon activé et du SiC.According to this process, working with briquettes of the reducing agent having a carbon excess of more than 50% by weight with regard to the indicated reaction and that in addition to SiC, activated carbon is formed at a temperature below 1600 degrees C in the briquettes, at the upper part of the low blast furnace, the quartz being reduced in the lower part of the low blast furnace using this activated carbon and SiC.
