Abstract
A system for producing cast components from molten metal. One form of the present invention includes a system for the precision pouring of molten metal within a casting mold. The precision pouring system is driven by a pressure differential.
Claims15
A system comprising:
- a crucible having a discharge;
- a vacuum furnace having said crucible positioned therein for melting metal material within the crucible;
- a metallic starter seed;
- a casting mold having an opening adapted to receive said starter seed and an internal cavity for receiving the molten metal material discharged from said discharge, said starter seed is positioned within said opening and contactable by the molten metal material received in said internal cavity;
- and
- a heat transfer apparatus in communication with the starter seed, the heat transfer apparatus structured to withdraw energy from the starter seed;
- wherein the metallic starter seed is arranged to project through a wall portion, the internal cavity of the casting mold disposed on a first side of the wall portion and the heat transfer apparatus disposed on a second side of the wall portion opposite the internal cavity.

A system comprising:
- a crucible having a discharge;
- a vacuum furnace having said crucible positioned therein for melting metal material within the crucible;
- a metallic starter seed disposed within the vacuum furnace, and having formed therein an inlet opening, an outlet opening, and a passageway extending through the interior of the metallic starter seed between the inlet opening and outlet opening, wherein the inlet opening, the outlet opening, and the passageway are configured to transmit a heat transfer media through the metallic starter seed;
- a casting mold having an opening adapted to receive said starter seed and an internal cavity for receiving the molten metal material discharged from said discharge, said starter seed is positioned within said opening and contactable by the molten metal material received in said internal cavity;
- and
- a heater coupled with said starter seed to selectively add energy to said starter seed during a first period, and wherein the starter seed is joined to the metal poured in said cavity and heat is withdrawn through said starter seed during the directional solidification of the metal material within said cavity.
