Abstract (en)

[origin: DE19905286A1] The invention relates to a working method and an installation for the pickling and cold-rolling of metal strips. Said installation is comprised of a metal pickling device, of a winder arrangement provided on the winding side of the metal pickling device, and of a cold rolling mill which are all arranged in a line. The invention is characterized by the alternative sequence of subsequent working steps: a) The strip exiting the metal pickling device, for a first reduction pass, is introduced into the cold rolling mill while bypassing the winder arrangement and is rolled out in a plurality of shaping passes or; b) the strip exiting the metal pickling device is wound into a coil on the winder arrangement and, after being unwound, is introduced into the cold rolling mill and is rolled in a plurality of shaping passes or; c) the strip exiting the metal pickling device is wound as a hot-rolled strip on the winder arrangement in order to produce a finished strip or; d) prepickled hot-rolled strips are fed to the winder arrangement, are introduced into the cold rolling mill when unwound, and are rolled in a plurality of shaping passes.
