ROLLING MILL

The invention relates to rolling production and can be used for improving technological parameters and rigidity of rolling mills, while a transforming duomills into universal ones. The rolling mill consists of bases (1) and bottom horizontal rollers (4) installed in top and bottom chucks (5, 6) and mechanisms for regulating the rollers and cassettes (15) with vertical rollers (16) mounted between the chucks (5, 6) of the horizontal rollers (4). In accordance with the invention, plates (7) are rigidly fixed to outer sides of the windows of the bases'(1) columns (2, 3). The plates (7) project from boundaries of the columns (2, 3). The parts of the columns are linked to each other with the aid of top and bottom beams (9, 10) on which an entry and delivery roller guides (11) are mounted. The cassettes (15) with the vertical rollers (16) are fixed with the aid of a wedge arrangement between the inner surfaces of the columns (2, 3) of the base (1) and the surface of the plate (7). The top beams (9) have a cross section of a trapezoidal form and bottom beams (10) are embodied in the form of a tube. The rolling mill additionally comprises a mechanism for the axial fixation of the chucks (6) of the bottom horizontal roller (4) and a mechanism for axial adjustment and fixation of the chucks of the top horizontal roller (4) in addition to mechanisms for bailing the chucks (5, 6) of the horizontal rollers (4) mounted in such a way that they can turn and be introduced into the space between the chucks (5, 6) of the horizontal rollers (4). This operation is carried out during changing of the callipers of the rollers (4) and dismantling the cassettes (15) together with the vertical rollers (16). L'invention concerne le domaine du laminage et peut s'utiliser pour améliorer les paramètres technologiques et la rigidité des cages de laminoir ainsi que dans la réfection des cages à deux cylindres (duo) à des fins de transformation en cages universelles. La cage comprend des bâtis (1), des cylindres horizontaux supérieur et inférieur (4) installés sur des empoises (5, 6), des mécanismes de réglage des cylindres et d'une cassette (15), les cylindres verticaux (16) étant installés entre les empoises (5, 6) des cylindres horizontaux (4). Selon l'invention, on fixe rigidement aux montants (2, 3) des bâtis, à l'extérieur de leurs fenêtres, des plaques (7) qui font saillie en dehors des montants (2, 3) et dont les parties sont reliées entre elles par des poutres supérieures et infér
