ABSTRACT:
A six-high multi-roll stand (1), has one top and one bottom work roll (2, 3) which are supported in chocks (4, 5), with one top and one bottom intermediate roll (6, 7) which are supported in chocks (8, 9), and with one top and one bottom back-up roll (10, 11) with bearings located in one top and one bottom chock (12, 13). Two functional units are integrated into windows (16) of two roll housings (14, 15) with four each hydraulic operating cylinder units (18, 18, 19, 19) located symmetrically and parallel to roll axis plan 17--17), each operating cylinder unit (18, 19) consisting of top operating cylinder (18a, 19a) with top actuating piston (20a, 21a) which acts on chock (12) of top back-up roll (10) and bottom operating cylinder (18b, 19b) with bottom actuating piston 20b, 21b) which acts on chock (13) of bottom back-up roll (11) for counterbalancing back-up roll (10), and two operating cylinders (18a, 18b; 19a, 19b) of each operating cylinder unit (18, 19) in common cylinder housing (22, 23). Double-acting actuating sleeves (24a, 24b; 25a, 25b) cause bending of intermediate rolls (6, 7) and work rolls (2, 3) and engage chocks (8, 9; 4, 5) of intermediate rolls (6, 7) and work rolls (2, 3) by means of projections (26).
