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.
L'invention concerne un laminoir à régulation bidimensionnelle de la déviation des cylindres, comportant principalement les montants de la cage du laminoir, des groupes de cylindres et des empoises. Dans le but de réduire au minimum la déviation des cylindres lors du laminage, il est prévu un système de support bidimensionnel constitué du bâti, des empoises et d'un dispositif de support central situé entre le bâti et les empoises. Ce dispositif de support central comporte des moyens de serrage et des blocs horizontaux, ainsi que des blocs verticaux. Ce laminoir équipé d'une telle structure permet de supprimer la déviation des cylindres, réduisant ainsi au minimum les tolérances d'épaisseur des sections des feuillards ou des produits plats laminés.
