Abstract

A method and apparatus for continuously casting metal strip are provided, in which molten metal is introduced between a pair of parallel chilled casting rolls via an elongate metal delivery nozzle disposed above and extending along the nip between the casting rolls to form a casting pool supported on the rolls and the rolls are contra-rotated to produce the solidified strip. The molten metal is then delivered into a trough of the nozzle through an entry nozzle having an upper inlet end for receiving molten metal from a tundish, and a lower outlet end extending into the trough of the delivery nozzle, and the outlet end of the entry nozzle has a bottom wall, elongated side walls spaced inwardly from the side walls of the delivery nozzle and outlets for molten metal in the side walls.
