Abstract: A method and apparatus for casting metal strip in which molten metal is introduced between a pair of parallel casting rollers via a metal delivery nozzle disposed above the nip between the rollers, wherein the delivery nozzle comprises an elongate trough to receive molten metal, a nozzle outlet slot extending longitudinally along the bottom of the trough, a baffle structure extending above the slot, and a pair of flow passage means spaced apart laterally of the trough, one to each side of the outlet slot and each providing for flow of molten metal from the trough interior above the baffle structure into the trough interior below the baffle structure.

Abstract: Method and apparatus for casting molten metal by passing molten metal form a casting pool above the nip of the pair of chilled rollers and thence through the pair of counter rotating chilled rollers, to thus form a thin sheet of solid metal. The molten metal is delivered to the casting pool from a metal delivery nozzle which contains an outlet flow passage at the bottom thereof, below the surface of the casting pool, through which the molten metal passes into the casting pool, which further contains a diffuser therein just above the outward flow passage, and which contains a pool of molten metal sufficiently deep that its surface is above the diffuser. The diffuser had a multiplicity of flow passages (holes) therein through which the molten metal, which is fed to the delivery nozzle, passes and is diffused into the outlet flow passage. An energy absorbing baffle means may be provided above the diffuser.

Abstract: Apparatus for continuous casting includes a tundish for containing molten metal and delivering the metal to a work zone where the metal solidifies as it is moved through the work zone in a continuous casting process. The tundish contains molten metal and includes an outlet and a pervious flow restricting element is positioned in the outlet. The element causes the flow of the metal to be distributed as it flows through the outlet and into the work zone to engage a growing shell of solid metal carried through the work zone by a chilled substrate. The molten metal acts to apply a pressure on the shell and to lubricate the moving shell. The arrangement minimizes exposure of liquid to air and minimizes opportunity for turbulence in the liquid contained in the work zone. A method of continuous casting is also described.
