Abstract: In a machine for continuous casting of metal, e.g. copper, having a grooved wheel 10 and closing band 15, coolant is sprayed on to the exterior of the wheel 10 or circulated against it and the walls 12-14 of the groove 11 have a thickness which is less than that at which the thermal stress in compression induced by the molten metal equals the yield point in compression of the walls. The thickness of low carbon steel walls 12-14 may be uniformly 0À12 inches or range between 0À25 and 0À50 inches. Copper walls may be 0À30 inches thick. The wheel 10 may be wedged or fit loosely between the edges 33, 34 of circular angle members 17, 18 bolted to rings 21, 25, the ring 25 being supported by studs 26 and nuts 28-31 or by a welded member from the ring 21 which is bolted to the wheel disc 23. The wheel 10 may be welded to the angle members 17, 18 and the nuts 29, 31 may be omitted, the studs being shorter. In a second embodiment, the wheel side walls (121, 131) taper from 0À25 to 0À5 inches, the outer faces being parallel and, for retention of the wheel in a coaxial position, those faces are welded to the angle members (171, 181) or the wheel is supported on brackets (42) on the ring (211). To form a coolant channel (40) around the wheel (101), there may be a partition (41) extending between the rings (211, 251). The low carbon steel wheel is made by welding the abutted ends of sheet stock 0À12 inches thick or of a 3 inch rolled section which has been bowed on a ring-forming machine.
