Abstract

L'invention concerne un procédé de galvanisation d'une bande métallique (3) dans une ligne (1) de galvanisation en continu, la ligne (1) de galvanisation comprenant une gaine continue (23) de circulation d'une atmosphère réductrice comportant un gaz inerte et de l'hydrogène, dans lequel, avant de plonger la bande métallique (3) dans un bain (13) de zinc liquide ou d'un alliage de zinc liquide, on l'expose à cette atmosphère réductrice pour éliminer des oxydes présents sur la surface de la bande métallique (3), le procédé étant remarquable en ce que pour renouveler l'atmosphère réductrice dans ladite gaine (23), on y injecte le gaz inerte et l'hydrogène en réglant le débit d'hydrogène en fonction de la quantité de surface de la bande métallique à traiter par unité de temps.
