<p>An improved nozzle (14) is disclosed for a strip casting apparatus wherein molten metal is delivered to a casting surface located within 3.048mm (0.120 inch) of the nozzle (14) and is movable past the nozzle (14) at a speed of from 61 to 3048 metres (200 to 10,000 linear surface feet) per minute. The improved nozzle (14) comprises a pair of spaced orifice lips (18,19) substantially parallel to and facing one another, with the spacing being substantially uniform throughout the majority of the longitudinal extent of the nozzle (14). The peripheral end portions of the orifice lips (18,19) continuously diverge outwardly from one another for a length of less than three times the substantially uniform spacing between the lips (18,19) and for a height of less than two times the substantially uniform spacing between the lips (18,19).</p> |
