METAL DELIVERY SYSTEM FOR CONTINUOUS CASTER

摘要

Method and apparatus for continuously casting metal strip. Molte n metal is introduced between a pair of parallel chilled casting rolls (16) via an elongate metal delivery nozzle (18) disposed above and extending along the nip between the casting rolls (16) to form a casting pool (68) supported on the rolls and contra-rotating the rolls to produce a solidified strip (20). The molten metal is delivered into a trough (67) of the nozzle (18) through an entry nozzle (18) having an upper inlet end for receiving molten metal from a tundish, and a lower outlet end (84) extending into trough (61) of the delivery nozzle (19). The outlet end (84) of entry nozzle (18) has a bottom wall (86), elongate side walls (88) spaced inwardly from the side walls (62) of the delivery nozzle (19) and outlets (92) for molten metal in the side walls (88).
