Abstract

L'invention concerne un procédé de traitement de bains d'acier en fusion que l'on désoxyde et calme et/ou que l'on aillie et/ou que l'on soumet à un traitement métallurgique ultérieur dans un récipient de coulée en utilisant une matière dégageant de l'anhydride carbonique lors du chauffage. Le jet d'un bain en fusion pénétrant dans le récipient de coulée à partir d'un four de fusion métallurgique est entouré d'une matière à grains fins dégageant de l'anhydride carbonique.
