Continuous treatment, preferably cleaning, of a metal strip by means of a treatment liquid, especially an etching liquid

摘要

Continuous treatment, preferably cleaning, of a metal strip by means of a treatment liquid, especially an etching liquid, where the metal strip is passed horizontally through a tank containing the treatment liquid, especially an etching tank having at least one backwash device positioned relative to the metal strip, and which can be positioned differently in response to the action of further forces, acting especially via the metal strip. An independent claim is included for a device for carrying out the process as described above.
