Abstract
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 and/or a submerged flow modifier member disposed between at least one of the interior surfaces and the submerged entry nozzle. The surface and/or submerged flow modifiers work to impede the formation of waves in the upper surface of the molten metal. The present invention also includes a method for improving the quality of a continuous casting process.
