ABSTRACT:
A metal strip casting apparatus and a method of casting continuous metal strip includes assembling a pair of counter-rotatable casting rolls having casting surfaces positioned laterally forming a nip between for casting, and delivering molten metal through a delivery nozzle disposed above the nip capable to form a casting pool supported on the casting rolls. The delivery nozzle comprises segments each having elongate nozzle body with longitudinally extending side walls, end walls and a bottom part to form an inner trough, a nozzle insert disposed above bottom portions of the inner trough of each segment and supported relative to the nozzle body through which incoming molten metal may be delivered to the inner trough of each 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.
