Abstract

L'invention concerne un procédé permettant de contrer les effets indésirables de la désintégration de flux d'acier en fusion dus à la croissance sous-jacente de bulles d'oxyde de carbone lorsque les flux d'acier en fusion sont exposés à des pressions réduites et qui permet ainsi de raffiner la ferraille liquide sensiblement de la même façon que s'il s'agissait d'un liquide de repos en fusion. La ferraille d'acier contaminée par du cuivre, de l'étain, du zinc et des substances organiques, telles qu'un revêtement de PVC, est préchauffée et fondue en continu au moyen de la circulation du liquide en fusion, puis raffinée en continu en ligne de façon à obtenir un acier liquide de haute qualité et des sous-produits métalliques non ferreux séparés par désorption physique simple à une pression réduite au moyen d'un gaz d'extraction inerte dans un désorbeur, puis par condensation de vapeur de fer par contact direct avec de l'acier liquide, enfin par condensation sélective du cuivre et par récupération de l'étain. La formation de dioxines dans de la ferraille contenant du chlore est évitée par épuration en ligne de gaz de pyrolyse formés pendant le préchauffage de la ferraille. La fusion initiale de ferraille préchauffée utilise la du liquide en fusion et la combustion de gaz au lieu de l'électricité dérivée des combustibles fossiles et, par conséquent, elle est éconergétique.
