The invention relates to a method for changing rolls, in particular, working rolls (7, 8) and/or intermediate rolls in a roll stand, such as a roughing down stand or finishing stand for rolling thick sheet iron. Said rolls comprise back up roller sets (5, 6) and working roller sets (7, 8). One individual locomotive mechanism (9) is used for changing the working rolls (7, 8) and/or for changing the back up rolls (5, 6) and/or for inserting or withdrawing a roll changing seat (11) by supporting the rolls on each other and subsequently withdrawing in the axial direction of the rolls on the operational side of the roll stand, from a roll hall (1) in a roll workshop (2) and back and for installing novel roll sets. The invention also relates to a device for carrying out said method. |
