Abstract
A bottom anode for a metallurgical vessel destined for producing a metal melt is formed by a metal bar provided with at least one through recess extending from outside of the metallurgical vessel as far as to within the metallurgical vessel. In order to substantially increase the service life of such a bottom anode, conforming it to that of a lining made of refractory material, the bottom anode, on the vessel internal-side end of the metal bar, is provided with a nose formed of metal melt produced within the vessel. The nose incorporates channels departing from the vessel internal-side end of the through recess of the metal bar, which is connected to a supply duct introducing liquid and/or solid hydrocarbons, and at least some of the channels reaching as far as the surface of the nose.
