ABSTRACT:
A vessel used for transfer of molten metal having a refractory filter wall with filters for removing inclusion from molten metal as it flows through the vessel. The refractory filter wall having passages sized according to a predetermined volume of molten metal that is to be filtered, the desired flow rate of molten metal through the vessel and the limiting characteristics of the filters. In another aspect of the invention, protrusions are provided on refractory walls of the vessel to enhance deposition of non-metallic inclusions on the protrusions by disrupting the boundary layer flow in the molten metal.
