Abstract: A self-baking extruded electrode for a submerged arc electric furnace includes [comprising: -] a metal outer casing (1), cylindrical in shape, on which electric contact plates (5) are applied for the electrical supply. The electrode includes [-] an inner part [comprising] with electrolytic paste (3, 7, 8) anchored to an anchoring core (2) disposed axially inside the casing (1)[, -] an extrusion device (10) is connected to [said] the anchoring core (2) to control axial sliding of [said] the inner part of the electrode with respect to [said] the casing (1)[, downward].
