Abstract
An apparatus for use in casting a metal article includes a furnace assembly into which a mold is raised and an annular fluidized bed adjacent to the furnace assembly. The mold is filled with molten metal and lowered into the fluidized bed. The molten metal is solidified in the mold as it is lowered into the fluidized bed. The mold and fluidized bed are then lowered. The fluidized bed is disposed in a container having annular inner and outer walls which are cooled and function as heat sinks. A mold support member may extend through a passage in the annular inner wall of the fluidized bed.
