ABSTRACT:
A thermally efficient method for the heating a gas permeable wall of a bonded refractory mold wherein the mold wall defines a mold cavity in which molten metal or alloy is cast. The mold wall is heated by the transfer of heat from hot gas flowing inside of the mold cavity to the mold wall. Hot gas is flowed from a hot gas source outside the mold through the mold cavity and gas permeable mold wall to a lower pressure region exterior of the mold to control temperature of an interior surface of the mold wall.
