Patent ID: 8225845

Claim:
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 with outlets having an upward direction discharge angle between 5 degrees and 45 degrees from the horizontal adapted to upwardly discharge a flow of molten metal to deliver molten metal to a casting pool along opposite sides of the segment, (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 flows from the segment through the outlets adapted to discharge the flow at an upward angle into the casting pool and substantially onto the casting rolls, and (d) counter rotating the casting rolls to form shells on the casting rolls and bring the shells together at the nip and deliver cast strip downwardly from the nip.
