Abstract (en)

The roller assembly, for continuous casting and hot rolling in a parallel and simultaneous extrusion of a number of rods or wires (b1-bn), uses vertical and horizontal roller arrays. A number of shaping holes (10) at the transfer molding dies take the rod/wire materials directly to be manipulated into the required structure. The transfer molding die for continuous cast material has squeeze rollers to force the material through the transfer molding die to be given round, oval or polygonal shapes. The holes follow a curved path (b) through the die. The transfer molding die has two separate water-cooled chambers (c1,c2), with recirculating coolant water at different temperatures (e1,e2).
