Abstract
L'invention concerne la métallurgie. La charge faisant l'objet de l'invention est du type composé de coke et de sciure de bois, et est caractérisée en ce qu'elle se compose : de 85 à 95 % en poids de coke comprenant une fraction de + 0,5 à 2 mm à raison d'au moins 90 % en volume et une fraction de + 2 à 10 mm à raison de 10 % en volume au maximum; et de 5 à 15 % en poids de sciure de bois. L'invention notamment pour la production d'ouvrages carbostraphitisés tels que : électrodes l'élaboration de l'acier au four électrique, blocs pour la fabrication de fonte en haut fourneau et pour la production de titane et de magnésium, anodes pour l'industrie chimique, ainsi que les procédés de réduction mis en oeuvre dans la métallurgie des non-ferreux et la sidérurgie.
