Abstract
A pickling system for surface treatment, using a pickling medium, of strip steel in the form of standard steel, electric strip, high-grade steel, and extra-high-strength and ultra-high-strength third-generation steel in order to thereby provide a surface suitable for a subsequent shaping process for further processing. The system includes a plurality of treatment tanks connected in series. The pickling system has a modular construction and, starting from the strip infeed, at least one first treatment tank in the form of a dipping bath module is provided in the working direction, downstream of which a plurality of treatment tanks in the form of spray pickling modules are arranged, and at least one final second dipping bath module is arranged downstream of the spray pickling modules.
