Abstract

L'invention concerne une installation de refusion sous laitier électroconducteur. Le but de l'invention est d'augmenter la vitesse de fusion sans pour autant agrandir l'aire (12) de la section transversale de l'électrode consommable (4). Pour ce faire, l'électrode est introduite à l'oblique dans la coquille (1) de l'installation de refusion sous laitier électroconducteur, de manière à ce que la surface fusible (13), significative de la vitesse de fusion, soit agrandie par rapport à l'aire (12) de la section transversale.
