ROLLING MILL OF SHEET FOUR-HIGH MILL Russian patent published in 2010 - IPC B21B31/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of metallurgy and may be used to develop relatively small forming rolls with barrel length of not more than 200…800 mm, sheet-rolling mills. Rolling mill of sheet four-high mill comprises two bed plates, hydraulic pressing device, working rolls with cushions and support rolls with cushions arranged in windows of bed plates. Each bed plate is arranged with protrusions on stands facing inside of bed plate window. Cushions of working rolls are coupled with hydraulic cylinders installed in protrusions of bed plates. Lower support roll is coupled with their cushions and cylinders of hydraulic pressing device, and upper one - with hydraulic cylinders installed in protrusions on stands. Between each pair of upper and lower cushions of support rolls there is a pair of spacer C-shaped brackets.

EFFECT: invention provides for simplified design of hydraulic pressing device and accordingly increased reliability of its operation, and for relatively low sheet mills, considerable cheapening of mill.
