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. Such an electrode consists of sections (5) Graphite and a ceramic lower part (2) together which is connected to the edible graphite tip (14). In the Inside the electrode is a cooling system made of copper pipes (4) arranged that up to a copper nipple (8) stretches to which the consumable graphite tip (14) is attached is. The ceramic electrode part (2) prevents the Electrode is damaged by highly spraying slag, making the life of the electrode simple can be increased significantly.
