METHOD OF HEATING CASTING MOLD

摘要

A thermally efficient method for the heating a gas permeable wall of a bonded refractory mold wherein the mold wall (10) defines a mold cavity (10a) is heated by the transfer of heat from hot gas flowing inside of the mold cavity (10a) to the mold wall (10). Hot gas is flowed from a hot gas source (30) outside the mold through the mold cavity (10a) and gas permeable mold wall (10) to a lower pressure region exterior of the mold (10) to control temperature of an interior surface of the mold wall (10).
