Abstract

L'invention concerne un procédé permettant d'enlever des particules et/ou des adhérences notamment de particules non métalliques et/ou d'oxyde métallique, de la surface d'un produit à laminer (1) comme des profilés, tôles, bandes ou équivalent prélaminés et de billettes, blooms, brames, brames minces ou équivalent coulés en continu. Des buses (4) placées sur au moins une poutre de décalaminage (2) délivrent des jets de liquide sous pression. La ou les poutres de décalaminage (2) tourne(nt) autour de son ou de leur axe longitudinal pendant le processus de nettoyage et l'axe de rotation est sensiblement parallèle à la surface de la pièce à nettoyer. L'angle relatif est variable entre la poutre de décalaminage (2) et le produit à laminer (1). L'invention concerne également un dispositif permettant de mettre en oeuvre ce procédé.
