The actuating rolls 7 can be tilted in the horizontal plane with respect to the back-up rolls such that the axes of the actuating rolls intersect the axes of the back-up rolls and the axes of the actuating rolls intersect each other. Lubricant supply 1 is provided to supply lubricant between each operating roll and each back-up roll to greatly reduce the thrust applied to the operating roll, whereby the rolling mill has an excellent ability to control the crown of the material being rolled.
