摘要：The apparatus includes a spray chamber having a transport device forpositioning a billet adjacent a nozzle for spraying a stream of molten metal onto thesurface of the billet. The billet is engaged by a tandem arrangement of holding deviceswhich are attached to driven ring gears. With the holding devices engaging the billetrotation of the ring gears rotates the billet about its longitudinal axis as the billet issprayed with molten metal from the nozzle. As the billet is rotated it is also movedlongitudinally by servo-cylinders attached to the ring gears. The servo-cylinders advanceand retract in sequence as the ring gears rotate to generate combined longitudinal androtational movement of the billet adjacent the nozzle. Thus a uniform layer of metal isdeposited over length of the billet to form a round billet exclusively by spray- casting.
