Beschreibung
Zusammenfassung:	The present invention refers to a method for treating in continuous the surface of a laminate made of stainless steel that comprises at least the steps of: (a) subjecting said laminate to an electrolytic pickling treatment in alternating current, in an aqueous electrolytic solution comprising at least HCl and Fe3+ ions; (b) subjecting said electrolytically pickled laminate to a chemical pickling treatment in an aqueous chemical pickling solution comprising at least HCl and Fe3+ ions; (c) subjecting said chemically pickled laminate to a surface finishing and surface passivation treatment. La présente invention concerne un procédé de traitement continu de la surface d'un stratifié fait d'acier inoxydable, comprenant au moins les étapes consistant à : (a) soumettre ledit stratifié à un traitement de décapage électrolytique sous courant alternatif dans une solution aqueuse électrolytique comprenant au moins de l'HCI et des ions de Fe3+ ; (b) soumettre ledit stratifié traité par décapage électrolytique à un traitement de décapage chimique dans une solution aqueuse de décapage chimique comprenant au moins de l'HCI et des ions de Fe3+ ; et soumettre ledit stratifié traité par décapage chimique à un traitement de finition de surface et de passivation de surface.
