DEVICE FOR COOLING ROLLS Russian patent published in 2016 - IPC B21B27/10 

FIELD: machine building.

SUBSTANCE: present invention relates to rolling. Device (1, 1′) for roller cooling (2), in particular working roll (2) for rolling of rolled material (3), includes arranged opposite to at least partial area of roll surface perimeter, cooling jacket (50, 60) to form cooling gap (5), through which cooling fluid medium flows, between this partial area of roll surface and cooling jacket (50, 60). Improved cooling conditions and simplified adjustment of device, enabling due to, device has lever (40, 44) rotatable around suspension points (8, 48), which can rotate in direction of roll surface and is connected with first, if seen in circumferential direction (U) roll (2), half (51, 61) of cooling jacket (50, 60), wherein cooling gap (5) can alternatively increase or decrease by turning lever (40, 44). Device also includes suspension point (88, 48) rotating around another one, variable-length linear guide (90, 99), which is connected with possibility of rotation with second, if seen in circumferential direction (U) roll (2), half (59, 69) cooling jacket (50, 60).

EFFECT: device also relates to system for cooling of roller and method of its cooling.
