ABSTRACT:
Twin roll casting method and apparatus in which molten metal is introduced between a pair of chilled rolls (16) via an elongate delivery nozzle (19) to form a casting pool (68) above the nip (69) between the rolls (16). Rolls (16) are rotated to cast a solidified strip (20) delivered downwardly from the nip (69). Delivery nozzle (19) comprises upwardly opening trough having side walls (62), a floor (63) and bottom outlet openings (64). A pair of upright flow barrier walls (84) stand up from floor (63) to define an internal trough channel (85) to receive the incoming flow of molten metal (65). Barrier walls (84) prevent direct flow of the incoming metal to the outlet openings (64).
