Patent ID: 8813828

Claim:
A method of continuously casting metal strip comprising: (a) assembling a pair of casting rolls laterally disposed to form a nip between them and to maintain a casting pool of molten metal supported by the casting rolls between side dams, (b) assembling an elongated metal delivery nozzle extending along and above the nip, the delivery nozzle having one or more segments extending longitudinally along the metal delivery nozzle, each segment having: a main portion having one or more outlets positioned longitudinally and oriented downwardly along the elongated metal delivery nozzle and adapted to deliver molten metal directed downwardly converging toward the nip while forming the casting pool supported on the casting rolls above the nip, and an end portion adjacent at least one of the side dams having a reservoir portion having at least one pair of passages adapted to deliver molten metal into the casting pool adjacent the side dams the flow from the at least one pair of passages converging beneath the reservoir portion, (c) delivering molten metal from a metal delivery system to the main portion of the segments to deliver molten metal through the one or more outlets directed to converge downwardly toward the nip while forming the casting pool of molten metal supported on the casting rolls above the nip, and through the at least one pair of passages in the reservoir portion in the end portion into the casting pool adjacent the side dams, and (d) counter-rotating the casting rolls to form shells on the casting surfaces of the casting rolls brought together at the nip to cast metal strip downwardly from the nip.
