ABSTRACT:
The invention relates to a rolling plant (100) and to a method for its operation. Known rolling plants (100) typically comprise a reversing stand (110) for rolling a metal strip (200) in a plurality of rolling operations until the metal strip has reached the desired thickness. The reversing stand (110) is typically assigned at least one reversing reel device (130), which has a reel mandrel (132), for temporarily storing the metal strip (200) after individual rolling operations. The known rolling plants (100) 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 (140) for placing a winding sleeve (134)onto the reel mandrel (132) before the metal strip (200) 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 (120) is still greater than the desired thickness but is already lower than a predetermined thickness threshold value.
