ABSTRACT:
The present invention provides at least one cylindrical, close-ended porous, ceramic molten metal filter element connected to an essentially horizontal porous ceramic sealing plate filter element. The cylindrical element extends vertically above the elevation of that sealing plate. The molten metal flow is introduced to the exterior of the close-ended cylindrical elements and the upper surface of the plate element. The cylindrical filter body elements rest on the sealing plate, thus the sealing plate provides all of the structural support for the assembly. The molten metal flows through the porous ceramic material of the cylindrical elements and the sealing plate element to be further flowed downstream, ultimately to the associated casting molds.
