HIGH-PRECISION ROLLING MILL WITH TWO-DIMENSIONAL FLEXURE CONTROL

摘要

A rolling mill with roll deflection bi-dimensionally controlled, mainly comprising: frames of the roll stand, roll groups and roll chocks. In order to minimize the roll deflection during rolling operation, the present invention provides a bi-dimensionally supporting system, consisting of frames, roll chocks and middle supporting device between said frames and roll chocks. The middle supporting device comprises screw-down means and horizontal blocks, as well as vertical blocks. The rolling mill with such structure makes it possible to suppress the roll deflection, thereby minimizing the tolerances in thickness of cross sections of the rolled strips or plates.
