BUILT-IN DEVICE FOR BENDING AND BALANCING ROLLERS FOR ROLLING MILL STANDS Russian patent published in 2016 - IPC B21B29/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to rolling. Apparatus comprises a bending device (8) in form of at least one of upper bending cylinder (9) with bending piston (11) adapted to interact with cushion (3) of upper working roll (2) and at least one lower bending cylinder (9') with bending piston (11') configured to interact with cushion (3') of lower working roll (2'), and attached to bending device (8) balancing device (12) in form of at least one cylinder (13) with balancing piston (14) configured to interact with cushion (5) of upper support roll (4). Reduction of dimensions and improving reliability of device is ensured due to that it has an upper movable slide (15) mounted to allow sliding at one end of balancing device (12), and a lower movable slide (15') mounted to allow sliding on other end of balancing device (12), wherein bending piston (11) of at least one of upper bending cylinder (9) is fixedly connected to upper movable slide (15) with possibility of movement of cushion (3) of upper working roll (2) via upper movable slide (15) and bending piston (11') of at least one lower bending cylinder (9') is fixedly connected to lower movable slide (15') with possibility of movement of cushion (3') of lower working roll (2') through lower movable slide (15').

EFFECT: rolling.
