Abstract

La présente invention concerne une électrode et un procédé de fonctionnement connexe, destinés en particulier aux fours sidérurgiques à arc électrique et analogues, laquelle électrode comprend des moyens qui permettent de projeter un fluide vers le bain métallique, le fluide précité comprenant un composant combustible riche en carbone se décomposant à la chaleur, en particulier un hydrocarbure gazeux choisi dans le groupe composé du méthane, de l'éthane, du propane, du butane et de mélanges de ces derniers, de façon à produire un nuage qui protège le bout de l'électrode et qui revêt d'une couche solide la surface en graphite de cette dernière.
