Abstract
An apparatus for a self-baking electrode includes an electrode having at least three zones, a first zone containing uncarbonized carbon-containing composition, a second zone which adjoins the first zone and in which the carbon-containing composition is present in a paste-like or liquid form, a third zone which adjoins the second zone and in which the carbon-containing composition is present in carbonized form, and a cylindrical housing which encloses at least the first and second zones. A tube can be lifted and lowered in a vertical direction at least partly within the zones and an extendable holding element for taking up tensile forces runs partly within the tube and partly outside the tube where a first end of the holding element (101) can be detachably connected to a fastening element, a second end of the holding element enters the third zone and is anchored there.
