Abstract:
1. A method of casting metal strip comprising: (a) assembling a pair of casting rolls laterally disposed to form a nip between them, (b) assembling an elongated metal delivery nozzle extending along and above the nip between the casting rolls, with at least one segment having a main portion and an end portion having a reservoir portion having passages adapted to deliver molten metal to a casting pool and an inner trough extending longitudinally through the main portion and into the end portion beneath the reservoir portion, with end walls at opposite ends thereof, the inner trough communicating with outlets adjacent bottom portions formed in each segment adapted to deliver molten metal to the casting pool, (c) introducing molten metal through the elongated metal delivery nozzle to form a casting pool of molten metal supported on the casting rolls above the nip, such that molten metal is caused to flow into the inner trough of the delivery nozzle, from the inner trough through the outlets and through the reservoir portion passages into the casting pool, and (d) counter rotating the casting rolls to deliver cast strip downwardly from the nip.
