ABSTRACT:
The free energy of a metal which will fill the sinkhead of an ingot mold is calculated by assuming the dimensions of a liner sized to achieve the selected sinkhead volume and calculating the maximum temperature which the liner would achieve upon filling the sinkhead with a molten metal. The free energy is maximized until the mass of the liner is minimized at a calculated temperature less than the melting temperature of the liner. A liner is formed having dimensions corresponding to those of the calculated minimum mass liner. The liner is inserted into a support structure which will rest on the ingot mold.
