Abstract
La présente invention concerne un procédé de commande d'aspiration de fumées d'échappement pendant un processus d'élaboration d'acier dans une louche d'élaboration d'acier, le procédé comprenant les étapes suivantes consistant à : - capturer au moins une image des flammes s'échappant de la partie supérieure de la louche d'élaboration d'acier, - calculer au moins une valeur représentant la taille et/ou l'intensité de la flamme sur la base de ladite image de flamme capturée, - mesurer une pression représentant la pression des fumées aspirées, - réguler l'aspiration des fumées en fonction de ladite valeur représentant la flamme et de la pression mesurée.
