Document Type and Number:
Japanese Patent JP7256336
Kind Code:
B2
Abstract:
Provided are: an upper work roll, radial bearings and a thrust bearing provided on a work side and a drive side of the upper work roll and supporting the upper work roll. Shift cylinders are provided on the work side of the upper work roll and apply forces in both a work side direction and a drive side direction to the thrust bearing. Shift cylinders are also provided on the drive side of the upper work roll and apply forces in both the work side direction and the drive side direction to the radial bearing 790B. The shift cylinders each apply a force in the same direction to the radial bearing and the thrust bearing when the upper work roll does not shift in an axial direction at least during rolling.
