ABSTRACT:
An improved nozzle is disclosed for a strip casting apparatus wherein molten metal is delivered to a casting surface located within about 0.120 inch of the nozzle, and is movable past the nozzle at a speed of from 200 to 10,000 linear surface feet per minute. The improved nozzle comprises a pair of spaced orifice lips substantially parallel to and facing one another, with the spacing being substantially uniform throughout the majority of the longitudinal extent of the nozzle. The peripheral end portions of the orifice lips continuously diverge outwardly from one another for a length of less than about three times the substantially uniform spacing between lips, and for a height of less than about two times the substantially uniform spacing between lips.
