Abstract
The invention relates to a method for rolling a metal band in a continuous line installation with coupling of the pickling and cold rolling processes. According to the invention, the composition of the pickling fluid is determined to allow the running of the band in the bath at a minimum speed of a few metres per minute, and similar running speeds are maintained in the pickling and rolling sections, during the operating phases, whereas the rolling conditions are determined in order to maintain the requested quality of the band at a minimum rolling speed that may be as low as 1 metre per minute.
