Abstract
An apparatus for use in casting a metal article includes a furnace assembly and a container which holds a fluidized bed. A mold support is movable relative to the furnace assembly to move a mold from the furnace assembly into the fluidized bed. A bame is disposed between the fluidized bed and at least a portion of the furnace assembly. The baffle may have a plurality of secondary openings which enable particulate to move from an upper side of the baffle into the fluidized bed. The baffle may be connected with the furnace assembly, the container which holds the fluidized bed, or floated on the fluidized bed itself. The baffle may be provided with flexible segments which engage the mold and at least partially block movement of particulate through a central opening in the baffle during withdrawal of the mold from the furnace assembly.
