Abstract

Die vorliegende Erfindung bezieht sich auf eine selbstkal- zinierende Elektrodenmasse für Elektrolichtbogenöfen, enthal- tend ein oder mehrere Kohlenstoffkomponenten und ein Bindemit- tel, wobei das Bindemittel Hartbitumen mit einer Nadelpenetra- tion bei 25°C nach DIN EN 1426 von 0 bis 20 pro 0.1 mm und/oder einem Erweichungspunkt (Ring und Kugel) nach DIN EN 1427 von 80°C bis 110°C, und mit einer Dichte bei 25°C nach DIN EN 52004 von 0.5 bis 2 g/cm3 ist, wobei die Elektrodenmasse einen polyaromatische Kohlenwasserstoffe oder PAK Gehalt von <500 ppm aufweist. Das Hartbitumen wird durch Flashdestillati- on von weichen und mittelharten Bitumensorten gewonnen und weist vorzugsweise einen hohen Schwefelgehalt auf.
