Abstract
The installation includes an in-line arrangement of a metal pickler, a reeling arrangement installed on the coiling side of the metal pickler, and a cold-rolling mill. The method includes ones of the following alternative sequences of work steps:(a) the strip leaving the metal pickler bypasses the reeling arrangement and is introduced into the cold-rolling mill for a first reduction pass and rolled out over the course of several deformation passes; or(b) the strip leaving the metal pickler is wound on the reeling arrangement into a coil; after the coil is switched to the uncoiling position, the strip is fed into the cold-rolling mill and rolled out over the course of several deformation passes; or(c) the strip leaving the metal pickler is wound as hot-rolled strip on the reeling arrangement to obtain the finished strip; or(d) pre-pickled, hot-rolled strips are sent to the reeling arrangement and then uncoiled from the uncoiler into the cold-rolling mill and rolled in several deformation passes.
