Abstract
Le procédé vise à réchauffer en continu du fer en fusion produit à partir de ferraille. On fait couler le fer en fusion 8 dans une chambre de réchauffage 7 séparée du récipient de fusion 1, mais en liaison directe avec ce dernier. On ajoute au fer en fusion 8 de l'oxygène et du combustible pouvant être en particulier du carbone solide. Application à la production de l'acier.
