ANORDNING FOR AXIELL JUSTERING AV EN ARBETSVALS I ETT VALSVERK

摘要

An apparatus for axially adjusting a work roll in a rolling mill. The apparatus includes an annular piston-cylinder assembly surrounding one end of the work roll. The cylinder is fixed relative to the roll chock and the piston, which is hydraulically actuated for reciprocal adjustment in opposite directions parallel to the rotational axis of the work roll, is connected through a thrust bearing assembly to the roll sleeve, the latter being fixed relative to the work roll and being both rotationally journalled in and movable axially relative to the roll chock.
