A method of and apparatus for casting metal strip involving assembling a pair of casting rolls laterally disposed to form a nip between them, assembling an elongated metal delivery nozzle extending along and above the nip between the casting rolls, with at least one segment having opposing side walls and end walls, an inner trough extending longitudinally within between side walls and forming passages between the side walls and the inner trough and communicating with side outlets adjacent bottom portions, introducing molten metal through the elongate 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 passages between the inner trough and sidewalls, and from the passages through the side outlets in a substantially lateral direction into the casting pool, and counter rotating the casting rolls to deliver cast strip downwardly from the nip.
A method of casting metal strip comprising:
A metal delivery apparatus for casting metal strip comprising a metal delivery nozzle having at least one elongated segment, each segment having opposing side walls and end walls, an inner trough extending along the side walls to form passages between the side walls and the inner trough, and communicating with side outlets adjacent bottom portions of the segments of the delivery nozzle extending along the segment, such that molten metal is capable of flowing into the inner trough, from the inner trough through the passages between the inner trough and side walls, and exit the delivery nozzle through the side outlets in a substantially lateral direction into a casting pool.
A metal delivery apparatus for casting metal strip comprising a metal delivery nozzle having at least one elongated segment, each segment having opposing side walls and an inner trough extending along the side walls to form a shoulder portion between the side walls and the inner trough, and a plurality of holes extending through each shoulder portion and communicating with side outlets adjacent bottom portions of the segments of the delivery nozzle extending along the segment, such that molten metal is capable of flowing into the inner trough, from the inner trough through the holes between the inner trough and side walls, and exit the delivery nozzle through the side outlets in a substantially lateral direction into a casting pool.
A metal delivery apparatus for casting metal strip comprising a metal delivery nozzle having at least one elongated segment, each segment comprising an outer piece forming opposing side walls and end walls, and an inner trough forming an inlet to receive molten metal and passages between the side walls and the inner trough, such that molten metal is capable of flowing from the inner trough through the passages between the inner trough and side walls, and from the passages exiting the delivery nozzle through the side outlets in a substantially lateral direction into a casting pool.
