ABSTRACT:
A rolling mill has a pair of working rolls each provided with one or more sag-compensating back-up rolls on the respective side of the rolling plane having a fixed support beam with a roll shell rotatable about the beam and hydrostatic support means mounted on the beam for exerting pressure against the shell. Two sag-compensating back-up rolls for each working roll define two support planes at an angle to each other. The support planes may be at equal angles to the rolling plane. With different diameter back-up rolls the support plane of the smaller diameter roll may be at a smaller angle to the rolling plane, and the smaller diameter roll may be on the downstream side of the working roll. Lateral support means for the working rolls may be provided by sag-compensating rolls or by hydrostatic support devices acting directly on the working roll surfaces. The lateral support forces may be controlled to counteract the tractive force on the material being rolled.
