Abstract

Le procédé de coulée électrique de laitier pour former des lingots à partir d'un mélange granulaire contenant du métal consiste à créer un bain de laitier au moyen d'électrodes en métal refroidies non consommables maintenant dans les couches supérieures du bain de laitier une température comprise entre 1750-1800 °C, à procéder à une alimentation graduelle, à partir de ce dernier, en mélange granulaire métallique à une vitesse égale à 1,0-1,5 fois la vitesse de sa fusion, à obtenir le bain de fusion de métal et à former un lingot.
