Patent
CA 2485633
The invention relates to a metallurgical treatment method on a metal bath. The inventive method comprises a first treatment involving the presence or formation of an acid slag on the surface of the metal bath and a second treatment involving the presence or formation of a basic slag on the surface of said metal bath. According to the invention, no intermediate deslagging is performed during said two processes, thereby ensuring that a physical separation exists between an acid slag zone and a basic slag zone on the surface of the metal bath.
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.
