Beschreibung
Zusammenfassung:	A method for producing a ferro-alloy, such as steel, in an electric arc furnace or other suitable metallurgical furnace is disclosed. The method comprises supplying a mixture of (a) a carbon-containing polymer that is capable of acting as a slag foaming agent and (b) another source of carbon into the furnace during at least a part of a power-on phase of the method. A metallurgical furnace is also disclosed. La présente invention porte sur un procédé de production d'un ferro-alliage, tel que l'acier, dans un four à arc électrique ou dans un autre four métallurgique approprié. Le procédé comprend la fourniture d'un mélange (a) d'un polymère contenant du carbone qui peut faire office d'agent de moussage de laitier et (b) d'une autre source de carbone dans le four pendant au moins une partie d'une phase de mise en service du procédé. L'invention porte également sur un four métallurgique.
