Abstract

Un procédé de traitement métallurgique sur bain métallique comprend un premier traitement impliquant la présence ou la formation d’un laitier acide en surface dudit bain métallique et un deuxième traitement impliquant la présence ou la formation d’un laitier basique en surface dudit bain métallique. L’on effectue les deux traitements sans décrassage intermédiare, en assurant en surface dudit bain métallique une séparation physique entre une zone de laitier acide et une zone de laitier basique.
