A method of controlling a roll gap between first and second work rolls () that includes defining a plurality of work surface locations spaced apart along the first work roll () in the longitudinal direction; obtaining a radius of the work surface () of the first work roll () at each of the work surface locations; based on the radii of the work surface locations, obtaining a longitudinal profile of the work surface (); based on the longitudinal profile, tilting the first work roll () relative to the second work roll () in the common plane in order to reduce a difference in the average size of the gap either side of a centerline (CL), which bisects the longitudinal axes of the first and second work rolls ().

Method of controlling a roll gap in a rolling mill

Roller table apparatus () for transporting a metallic product (P) to or from a mill stand, includes: first and second rolls (), outboard ends of the rolls are supported by respective outboard bearings and inboard ends of the rolls are supported by respective inboard bearings, such that each of the rolls is rotatable about its longitudinal axis (X, X); and at least one adjuster (), movable in use to displace at least one end of the rolls or the respective bearings of the roll so as to adjust an angle (&#x3b1;) of inclination of each of the longitudinal axes of the rolls with respect to a datum (D), thereby to adjust a pass-line height (h, h) of the product relative to the datum.
