Abstract

Es handelt sich um ein Verfahren zur Erzeugung von Gußeisen in verschiedenen Sorten mit unterschiedlichen Kohlenstoffgehalten. Bei der Gußeisenerzeugung wird mit einer bestimmten Einsatzgattierung, im wesentlichen bestehend aus bestimmten Anteilen Eisen, Koks und Kalkstein eine Gußeisensorte erzeugt. Für eine andere Gußeisensorte ist ein entsprechend anders zusammengesetzter Einsatz notwendig. Um den Betrieb eines Kupolofens flexibler zu gestalten, wird kohlenstoffhaltiges Material in staubförmiger Form zur Beeinflussung des Kohlenstoffgehalts des entstehenden Eisens in den Kupolofen eingeführt und zwar in einer vom Kohlenstoffgehalt der zu erzeugenden Gußeisensorte abhängigen Menge.
