  • Patent number: 6453986
    Abstract: A method and apparatus for continuously casting metal strip are provided, in which molten metal is introduced between a pair of parallel chilled casting rolls via an elongate metal delivery nozzle disposed above and extending along the nip between the casting rolls to form a casting pool supported on the rolls and the rolls are contra-rotated to produce the solidified strip. The molten metal is then delivered into a trough of the nozzle through an entry nozzle having an upper inlet end for receiving molten metal from a tundish, and a lower outlet end extending into the trough of the delivery nozzle, and the outlet end of the entry nozzle has a bottom wall, elongated side walls spaced inwardly from the side walls of the delivery nozzle and outlets for molten metal in the side walls.

  • Patent number: 6095233
    Abstract: Method and apparatus for continuously casting metal strip. Molten metal is introduced between a pair of parallel chilled casting rolls (16) via an elongate metal delivery nozzle (18) disposed above and extending along the nip between the casting rolls (16) to form a casting pool (68) supported on the rolls and contra-rotating the rolls to produce a solidified strip (20). The molten metal is delivered into a trough (67) of the nozzle (18) through an entry nozzle (18) having an upper inlet end for receiving molten metal from a tundish, and a lower outlet end (84) extending into trough (61) of the delivery nozzle (19). The outlet end (84) of entry nozzle (18) has a bottom wall (86), elongate side walls (88) spaced inwardly from the side walls (62) of the delivery nozzle (19) and outlets (92) for molten metal in the side walls (88).

  • Patent number: 5857514
    Abstract: A metal delivery nozzle (19) for delivery of molten metal to the nip between casting rolls in a twin roll caster to establish a casting pool supported above the nip. The trough (19) defines an open topped trough (61) to receive molten metal from a distributor. The bottom of the trough (61) is closed and the nozzle has side openings (64) and two large end openings (71) for delivery of molten metal from the trough (61) into the casting pool. The side openings (64) are longitudinally spaced circular holes disposed between unperforated end regions (72) of the nozzle.
