(54)    Title

A rolling mill with roll deflection bi-dimensionally controlled.

(57)    Abstract

A high-precision rolling mill with the flexture of the roll being controlled two-dimensionally which mainly comprises a mill stand, roll systems and roll supports. To minimize the flexural deformation of the rolls during rolling, the inventive rolling mill is also provided with a two-dimensional supporting system which is common ly composed of the mill stand, the roll supports and intermediate supporting means between the mill stand and the roll supports. The intermediate supporting device comprises pressing devices and horizontal pads, as well as vertical pad sets. The configuration of rolling mill results in the great reduction of the flexure, thus reducing the thickness error of cross-section of rolled plate and strip.
