The invention relates to a rolling plant () and to a method for its operation. Known rolling plants () typically comprise a reversing stand () for rolling a metal strip () in a plurality of rolling operations until the metal strip has reached the desired thickness. The reversing stand () is typically assigned at least one reversing reel device (), which has a reel mandrel (), for temporarily storing the metal strip () after individual rolling operations. The known rolling plants () also have a sensor device for determining the thickness of the metal strip. In order to cost-effectively achieve high flexibility in the use of primary materials of different strip thicknesses, it is proposed according to the invention that the rolling plant has a winding sleeve exchange device () for placing a winding sleeve ()onto the reel mandrel () before the metal strip () is temporarily stored and for removing the winding sleeve from the reel mandrel between two rolling operations when the thickness of the metal strip determined by the sensor device () is still greater than the desired thickness but is already lower than a predetermined thickness threshold value.

Rolling installation and method for producing metal strips

Steel strip issues continuously from a downstream end of a rolling line and can be wound up there on a coiler. An inspection table downstream of the rolling line has a surface aligned with the downstream end and the strip emerging therefrom. The coiler is below a plane of the table surface. During normal rolling the strip is deflected downward to the coiler and reeled up. For inspection of the strip, the strip is cut transversely to produce a new leading end and is fed starting at this end toward the table without substantial deflection. Then the strip is cut again upstream of the new leading end to form a strip sample separate from the strip emerging from the rolling line, which sample is fed to the table and arrested and inspected while strip emerging from the line is deflected back down to the coiler to continue coiling it up.
