ABSTRACT:
An eight-roll cold strip mill for producing strips of wide width and light gauges, utilizing upper and lower small diameter work rolls, a pair of backing rolls for each work roll, and a driven roll for each work roll contacting the backing rolls thereof. The work rolls, backing rolls and driven rolls are located within a mill housing. The vertical roll separating forces are transmitted to the housing by a plurality of pressure elements operatively connected to the housing and evenly and closely spaced along and contacting the faces of the driven rolls. The horizontal components of the roll separating force are transmitted to the housing by a plurality of pressure elements operatively connected to the housing and evenly and closely spaced along and in contact with the faces of the backing rolls. Each pressure element comprises an arcuate anvil having a concave portion or cavity corresponding to the radius of the respective one of the driven and backing rolls to be supported thereby. The anvil of the pressure element is surrounded by an endless chain of rollers, rotatable thereabout.
