CA 2399754

The invention relates to a method and device for pickling rolled metal, in particular steel strip, whereby the metal strip (1) is fed to a controlled pickling method. The aim of the invention is to carry out the pickling method, taking into account not just the usual parameters, but also additional parameters from outside the pickling bath. Said aim is achieved, whereby the pickling method is controlled by parameters of the coil (2) and/or the metal strip, determined and/or measured before the metal strip is fed into the pickling section (3), in addition to the pickling medium parameters.

L'invention concerne un procédé et un dispositif pour le décapage d'un feuillard métallique laminé, notamment d'un feuillard d'acier. Selon l'invention, le feuillard métallique (1) est soumis à un décapage régulé. L'invention vise à permettre d'effectuer le décapage non seulement sur la base des paramètres de décapage habituels, mais aussi en tenant compte de paramètres supplémentaires, en dehors du bac de décapage. A cet effet, le décapage est régulé non seulement sur la base des paramètres de la substance de décapage, mais aussi en fonction de paramètres du rouleau (2) et/ou du feuillard métallique (1), déterminés et/ou mesurés avant l'introduction du feuillard métallique (1) dans la partie de décapage (3).
