Abstract
Die Erfindung bezieht sich auf ein Verfahren zur Verbesserung des Reduktionsgrades von Metallkomponenten in einem Chromitkonzentrat, wenn Ferrolegierungen geschmolzen werden, die für die Herstellung von Edelstahl geeignet sind. Das Chromitkonzentrat wird gemeinsam mit Nickel-hältigem Rohmaterial zugeführt, so dass mittels der Menge an Nickel-hältigem Rohmaterial ein gewünschter Reduktionsgrad für die Metallkomponenten der Ferrolegierung erreicht wird.
