Abstract: A system for continuously casting substantially rigid metallic sheet is disclosed wherein a continuous stream of molten metal is fed into a plenum chamber, the metal directed into the nip between spaced casting members with at least one having recesses in the surface to provide a pattern of spaced projections on at least one side of the sheet. The pressure of the molten metal is only sufficient to cause the metal to fill the major portion of the chamber and the casting members are cooled sufficient to place the solidification point of the molten metal at the projections to cause a progressive laying on of the metal and prevention of the rupture of the formed meniscus adjacent the nozzle orifice. The apex of each recess in the process at the point of laying on is momentarily at a maximum from about 17 to 200 percent greater than the nominal spacing at the nip of the members and the depth of the recess is at least about 5 percent of said nominal spacing but not greater than about 100 percent.
