Abstract

1,108,480. Rolls. BERGWERKUND WALZWERK-MASCHINENBAU G.m.b.H. 13 Jan., 1967 [19 Jan., 1966], No. 1971/67. Heading B3M. A working roll for a rolling mill has a cavity 34 filled with liquid, which is pressurized in order to camber the roll. In one embodiment, the liquid in the roll cavity 34, formed between a core 29 and a tightly fitting shell 30, is pressurized by the actuation of a piston 39 in a bore 33 caused by the displacement of a piston 32 mounted in the roll neck 31 The piston 32 is displaced by pressure liquid flowing through a pipe 38 and a stationary pin 36, to which is also connected a filling conduit 40. In another embodiment, the pressure liquid is supplied through a pipe (27) (Fig. 3, not shown) to a stationary cylinder (23), the piston (28) of which is displaced to actuate through thrust bearings (26) a piston (21) movable in a bore (22), the liquid in the cavity (29) being thereby pressurized. In a further embodiment, the liquid is supplied under pressure through a rotary inlet (15) (Fig. 2, not shown) to the cavity. (13), from which the liquid is discharged at a predetermined rate. The roll may alternatively be hollow (Fig. 1, not shown) to form the cavity (4).
