摘要： A roll for a rolling mill comprises a roll body (20) including a portion (19) which affords a rolling surface and is integral with a cylindrical bearing portion (18) for rotationally supporting the roll at each end thereof. The roll body (20) affords an internal bore in each longitudinal half thereof, the inner portion (23,24) of which is tapered and receives at least one piston (25 to 28) which together with a shaft (29,30) in the outer portion (21,22) of the bore defines at least two liquid chambers (33 to 37) to which pressurised liquid may be selectively applied to move the piston longitudinally into and out of contact with the tapering surface of the associated bore to deform the rolling surface.

摘要： The roll comprises a roll core (1a) on which a sleeve (2) is shrink-fitted to define an annular space (5) at each end of the roll between the roll core and the sleeve. Two annular pistons (45,46) are accommodated within the annular space and hydraulic fluid lines which extend through the roll core communicate with hydraulic fluid chambers (50,51,52) at each end of the pistons. Valves (66,67,66′,67′) are provided in the hydraulic fluid lines and one or more position sensors (61,62) is arrranged to produce a signal indicative of the axial position of each piston. A control unit (69) is connected to the position sensors and arranged to control the valves in response to the said signal and thus to control of the positions of the pistons.
