Abstract

L'invention concerne un four électrique (1) avec une chambre réceptrice (2) pour de la matière en fusion (3), sachant qu'au moins une électrode (4, 5) s'enfonce dans la chambre réceptrice (2) et sachant que des moyens (6) sont présents pour l'introduction de poussières dans la chambre réceptrice (2). L'invention vise à permettre un apport amélioré de la poussière, avec un traitement simple de celle-ci. À cet effet, selon l'invention, les moyens (6) pour l'introduction de poussières dans la chambre réceptrice (2) comprennent un perçage (7) s'étendant au moins partiellement dans la direction longitudinale (L) de l'électrode (4, 5).
