Abstract
With reference to FIG. 4 , a metal delivery nozzle (19) for delivering molten metal to a nip between a pair of strip casting rollers comprises an upwardly opening inlet trough (61) to receive a series of free falling vertical stream (65) of molten metal and a metal flow passage (62) extending downwardly from the bottom of the inlet trough (61) to a metal flow outlet slot (69). Trough (61) has a side wall surface (64) which slopes downwardly and across the trough to the upper end of the metal flow passage (62). The free falling streams (65) impinge on side wall surface (64) at an acute angle of impingement such that the molten metal tends to adhere to that wall surface and to spread into the form of a sheet (70) flowing down the side wall surface.
