摘要
The invention relates to a device and a working method for automatically changing the sets of rolls comprising work rolls, backup rolls and intermediate rolls of a single-stand or multi-stand strip rolling mill, by means of a roll changing carriage (2) which can be displaced transversely with respect to the strip rolling stand (1) and a removal crossbar (3) provided for the removal of the set of backup rolls (10/11). In order to shorten the roll changing times and to automate the changing of the rolls, it is proposed that the removal crossbar (3) can be positioned on the roll changing carriage (2) and is provided with wheels (4) on which the removal crossbar (3) can be moved in working steps according to the invention out of the roll changing carriage (2) on guide rails (5) running parallel to the rolls (10/11) into the strip rolling stand (1) on the intermediate roll rails (8), and can be pulled out of the strip rolling stand (1) together with the set of backup rolls (10/11).
