Abstract
A layer of hollow spheres is floated on a fluidized bed beneath a furnace. A mold containing molten metal is heated in the furnace to melt the molten metal. The mold is then moved from the furnace through the layer of hollow spheres into the fluidized bed. As the mold moves into the fluidized bed, heat is conducted form the mold and the metal is solidified.
