ABSTRACT:
An installation for pickling rolled metal strip in order to remove oxides formed thereon. The strip is fed horizontally through an acid solution bath over a series of deflecting rollers rotating about axes perpendicular to the feed direction of the strip and defining, within a single vessel, outward and return paths comprising at least three superposed sections, and walls dividing the vessel into at least two superposed treatment cells of a height which is low enough for the treatment liquid to be driven along by the feeding of the strip by pumping action.
