Abstract (en)

[origin: EP0908246A1] Rolls in a rolling mill cage are changed using a guidance chassis and a device with a hook to pick up the intermediate rolls or the work rolls alone or the whole assembly by their ends. A device for changing rolls in a rolling mill cage comprises a guidance chassis (29) with an extraction device (28) to slide parallel to the axes of the rolls. A device (35) for picking up each of the work rolls (4) by its end and a moveable hook (37) for each of the two intermediate rolls (3), for the demounting and remounting either the two work rolls (4) alone or the assembly of work rolls (4). This also applies to the intermediate rolls (3) of which the dressings (6) roll on rails (8, 9) and are arranged respectively on the cage (1) on the guidance chassis. An Independent claim is also included for the method for changing rolls using this device.
