Patent ID: 7926550

Claim:
An apparatus for casting metal strip comprising: (a) a pair of counter-rotatable casting rolls having casting surfaces laterally positioned to form a nip therebetween through which cast strip can be cast, and on which a casting pool of molten metal can be formed supported on the casting surfaces above the nip with side dams adjacent ends at casting rolls to confine the casting pool, (b) a delivery nozzle disposed above the nip capable of delivering molten metal to form the casting pool supported on the casting rolls, the delivery nozzle comprising: segments each having an elongate nozzle body with longitudinally extending side walls, end walls and a bottom part to form an inner trough, a nozzle insert separate from a shroud of a metal distributor disposed above bottom portions of the inner trough of each segment and supported relative to the nozzle body and through which incoming molten metal may be delivered to the inner trough of the segment of the delivery nozzle, and the elongate nozzle body of each segment having passageways in fluid communication with the inner trough and outlet openings capable of discharging molten metal from the nozzle body outwardly into the casting pool, and (c) a metal distributor capable of supplying molten metal to form the casting pool through the nozzle insert, inner trough and passageways of each segment of the delivery nozzle.
