Abstract:
A method of casting metal strip comprising:introducing molten metal between a pair of chilled casting rolls via an elongate metal delivery nozzle disposed above and extending along the nip between the rolls to form a casting pool of molten metal supported above the nip and confined at the ends of the nip by pool confining end closures, androtating the rolls so as to cast a solidified strip delivered downwardly from the nip;wherein the bottom of the nozzle trough is provided with a floor and molten metal is caused to flow from the trough into the casting pool through nozzle side openings formed at the bottom corners of the trough and wherein the method comprises introducing the molten metal into the trough in a series of free-falling streams impinging directly on the trough floor whereby to cause molten metal of said streams to fan outwardly across the trough floor and through the nozzle openings at the nozzle floor level into the casting pool in mutually oppositely directed jet streams.
