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.
