Beschreibung
Zusammenfassung:	This invention relates a pickling process of a metallic strip comprising the steps oh - passing said metallic strip through at least a pickling bath being at a temperature between 1 and 100°C, - applying an alternating current, having a current density of 1x102 to 1x105 A.m-2 of unit surface of said metallic strip to said metallic strip passing through said at least one pickling bath. La présente invention concerne un procédé de décapage d'une bande métallique comprenant les étapes consistant à faire passer ladite bande métallique à travers au moins un bain de décapage à une température comprise entre 1 et 100 °C, à appliquer un courant alternatif, ayant une densité de 1x102 à 1x105 A.m-2 de surface unitaire de ladite bande métallique à ladite bande métallique passant à travers ledit au moins un bain de décapage.
