Continuous process of increased cost effectiveness and efficiency for surface treatment, preferably cleaning, of a metal strip by means of a treatment liquid, especially an etching liquid

摘要

Continuous process for surface treatment, preferably cleaning, of a metal strip by means of a treatment liquid, especially an etching liquid where the metal strip is traversed horizontally through a tank, especially a flat etching tank of specific width and length. Part of the treatment liquid is pumped out of the tank, preferably at the height of the metal strip, by means of a line stream injector pump (sic) using a propellant liquid. An independent claim is included for a device for continuous cleaning of a metal strip as described above.
