Abstract
This invention relates to an installation for pickling a metal band by immersion through at least one bath (3) filled with a pickling liquid contained in a tank (1).According to the invention, each tank (1) is provided with at least one row of injection nozzles (5) distributed longitudinally and supplied with pressurized pickling liquid in order to make at least one series of liquid jets reaching inside the bath (3), whereas the said nozzles (5) are placed at different levels matching the shape of the curve followed by the band (2) in the tank (1) so that the liquid jet injected into the bath (3) by each nozzle (5) is directed straightforwardly to the portion (23) of the band (2) passing in front of the nozzle in question.
