Abstract

Electric furnace arrangement including a furnace vessel with liftable and lowerable lid penetrated by at least one electrode. The electrode is fastened to a liftable and lowerable supporting construction by first clamping devices. For lifting the lid, a further clamping device for the electrode is provided on the lid, at least one coupling element is provided on the supporting construction and at least one counter-coupling element is arranged on the lid, which can be brought into and out of engagement with the coupling element. A connecting element can be provided between coupling element and supporting construction.
