The invention is directed to a method for controlling foamed slag in a stainless melt in an electric arc furnace. According to the invention, the slag level in the electric arc furnace is continuously detected thermographically as a function of time and slag level, and the addition of foaming material is controlled depending on the temperature and temperature gradient.
L'invention concerne un procédé de régulation du laitier moussant dans un four à arc électrique. Le procédé selon l'invention consiste à détecter en continu la hauteur du laitier dans le four à arc électrique par thermographie en fonction du temps et de la hauteur du laitier, et à réguler l'addition d'une matière moussante en fonction de la température et du gradient de température.
