The apparatus of the present invention includes a molten metal vessel system for casting molten metal, the system comprising: (a) a vessel containing a molten metal adapted to contain and dispense the molten metal for casting, the vessel having interior surfaces and the molten metal forming an upper surface; (b) a submerged entry nozzle extending below the upper surface; and (c) a surface flow modifier member disposed between at least one of the interior surfaces and the submerged entry nozzle, and in sufficient proximity to the upper surface of the molten metal so as to impede the formation of waves in the upper surface of the molten metal. The present invention also includes a method of providing a flow of molten metal for continuous casting.
