Abstract
Electrodes for arc furnaces comprising a top portion (5) of metal and a replaceable bottom portion (6) of material which is only slowly consumable, being substantially cylindrical shape and the portions being interconnected by means of a screw nipple (1) or the like and the top portion has a liquid cooling device with a header duct (2) and a return duct (3) and the top portion (5) is advantageously protected in the bottom region thereof by means of an insulating coating of high temperature stability representing a detachably surmountable moulding. An electrically conductive intermediate layer of high temperature stability can be provided between the insulating moulding and the top portion. The electrodes are only slightly trouble prone, have emergency operating properties, have a high mechanical stressability and are easy to repair.
