Abstract

Eine solche Elektrode setzt sich aus Teilstücken (5) aus Graphit und einem keramischen Unterteil (2) zusammen, an den die verzehrbare Graphitspitze (14) anschliesst. Im In­ nern der Elektrode ist ein Kühlsystem aus Kupferrohren (4) angeordnet, das sich bis zu einem Kupfernippel (8) er­ streckt, an der die verzehrbare Graphitspitze (14) befestigt ist. Der keramische Elektrodenteil (2) verhindert, dass die Elektrode durch hochspritzende Schlacken beschädigt wird, wodurch die Lebensdauer der Elektrode in einfacher Weise wesentlich erhöht werden kann.
