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).
