Abstract
A method operating a pickling installation for pickling rolled strips comprises several consecutively disposed pickling basins filled with a pickling agent containing acid, through which the strip 4 is passed. A pickling agent containing acid is injected through injection nozzles disposed at least on the sides of the basin. A flexible adaptation to the respective pickling task with the aim of a reduced pickling time period is made possible if the nozzle injections on the sides are actuated variably. The pickling installation is provided for this purpose on both sides of the plurality of the basins, with injection nozzles above and below the strip traveling plane and upstream or downstream of base slide pads located in the basin.
