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.

Metal delivery system for continuous caster

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.

Strip casting

Method and apparatus for casting molten metal by passing molten metal form a casting pool above the nip of the pair of chilled rollers and thence through the pair of counter rotating chilled rollers, to thus form a thin sheet of solid metal. The molten metal is delivered to the casting pool from a metal delivery nozzle which contains an outlet flow passage at the bottom thereof, below the surface of the casting pool, through which the molten metal passes into the casting pool, which further contains a diffuser therein just above the outward flow passage, and which contains a pool of molten metal sufficiently deep that its surface is above the diffuser. The diffuser had a multiplicity of flow passages (holes) therein through which the molten metal, which is fed to the delivery nozzle, passes and is diffused into the outlet flow passage. An energy absorbing baffle means may be provided above the diffuser.
