ABSTRACT:
Method and apparatus for casting metal strip in which molten metal is introduced between a pair of parallel casting rollers (16) via a tundish (18) and metal delivery nozzle (19b). Casting rollers (16) are cooled so that shells solidify on the moving roller surfaces and are brought together at the nip between them to produce a solidified strip product (20) at the roller outlet. A casting pool is established by pouring a first batch of molten metal at a relatively high temperature above the liquidus temperature of molten metal through the delivery nozzle (19b) and is thereafter maintained by pouring through the delivery nozzle (19b) a second batch of molten metal at a relatively lower temperature. The bottom of the tundish (18) is formed with a well (26) to hold the first batch of molten metal and there is heating means (8) to heat the metal in the well (26).
