Abstract
Dans ce procédé pour le post-traitement d'un bain de fonte, désulfurée et alliée au Mg, destinée à la production de fonte à graphite sphéroïdal, le bain subit un post-traitement par des gaz ou des mélanges gazeux, qui sont introduits dans le bain à l'aide de lances d'insufflation ou de tampons poreux. L'invention trouve son application principale dans l'amélioration de la qualité des articles en fonte.
