ROLLING MILL Russian patent published in 2009 - IPC B21B13/00 

FIELD: metallurgy.

SUBSTANCE: rolling mill contains bed, working, interim, pressure and/or backup rolls, roll chocks, electromechanical, hydraulic and/or electromagnetic screwdown structures for creating effort of rolling, bending, counter bending and rolls crossing, constant magnetic bases, installed on vertical butt planes of chocks, and electromagnets, including magnetic bases, enveloped by coils of constant magnet neutralisation, installed opposite it on internal vertical planes of bed port with ability of its location relative to each other by analogous poles according to scheme S-S or N-N or analogous and opposite poles according to scheme S-S and N-S or N-N and S-N, at that at its location relative to each other by analogous poles roll chocks are implemented with ability of neutral position and its location in the same plane, perpendicular to rolling plane, and at location of it relative to each other by analogous and opposite poles roll chocks are implemented with ability of movement to one or different sides with respect to internal vertical planes of bed port or closely to it occlusion, at that magnetic bases and coils of neutralisation are outfitted by facilities for regulation of values of interacting magnetic fluxes. Furthermore, magnetic bases can contain of several co-axial installed sections, and external surface of magnetic bases can have form of concave lens with focus, located on the same axes with rolling node center of gravity.

EFFECT: increasing of rolls steadiness at the rolling process.
