Abstract

An arc furnace electrode comprises a top portion (5) of metal and a consumable bottom portion (6) of carbon material of substantially cylindrical shape connected to each other by means of a screw nipple (1) or the like. The top portion (5) has a liquid cooling device with a feed duct (2) and a return duct (3). The bottom region (12) of the top portion (5) can be protected advantageously by a high temperature resistant covering (4). The carbon material of the bottom portion (6) is formed only partially of graphite structure elements or is free thereof. The electrode is employed in a method for the production of steel.
