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 (19). 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 clean head end of the strip (20) is formed by adjusting the nip of the casting rollers to form a transverse bulge (103) across the width of the strip. The two separate solidified metal shells (105) and defines a line of weakness across the width of the strip. The strip separates at the line of weakness to form a clean head end for the following strip.
