Abstract: 1,251,916. Rolling mills; casting metals. CYCLOPS CORP. 11 March, 1970 [14 March 1969], No. 11761/70. Headings B3F and B3M. [Also in Division B5] A rolling mill for producing longitudinally tapered sheets or sections comprises a pair of hollow rolls 1 and 2, Fig. 2, between which a workpiece is rolled, each roll having a cylindrical inner surface and a tapered wall thickness for imposing corresponding taper on the workpiece. Each roll is supported internally by at least one roll 7<SP>1</SP>, and one or both rolls are driven by rolls 5<SP>1</SP> and 6<SP>1</SP>. The tapered wall thickness may be arranged by providing a wall of uniform thickness having one or more tapered grooves formed in its surface. A cylindrical inner sleeve of constant wall thickness may be mounted within each roll, the drive and supporting rolls then contacting the inner sleeve. The mill may be used for compacting metal powder into a tapered workpiece by providing a hopper 50 above the two rolls, the flow of powder from the hopper being controlled by flaps 51. Gates 53 and 54 hold the powder at the roll nip before rolling starts. In a similar arrangement, the rolls may be used for continuous casting. Liquid metal is fed from a tundish aligned with the rolls, the initial flow of metal being controlled by a dummy slab or gate arrangement. The rolls are cooled, e.g. by water, and may be oscillated as with a casting mould. Four rolls may be arranged with their axes in a common plane, Fig. 5, to produce a section 45. The profiles of the roll peripheries are conjugate and are arranged to taper the section during rotation of the rolls. Driving rolls 34-37 are located within the respective rolls. Several roll stands may be arranged in tandem to produce tapered products.
