Abstract
A method of forming a casting using a casting apparatus is disclosed, the method including the steps of lowering a ladle having a hollow interior into a source of molten material and an aperture facilitating flow into the hollow interior, filling the interior of the ladle with the molten material through the aperture, introducing an inert gas into a portion of a nozzle, removing the ladle from the source of molten material, causing the nozzle to contact a casting mold, and pressurizing the hollow interior with an inert gas to cause the molten material to flow into the casting mold.

A method of transferring a molten material to a casting mold, the method comprising:
- lowering a ladle having a hollow interior into a source of molten material and an aperture facilitating flow into the hollow interior;
- filling the interior of the ladle with the molten material through the aperture;
- introducing an inert gas into a portion of a nozzle;
- removing the ladle from the source of molten material;
- causing the nozzle to contact a casting mold;
- and
- pressurizing the hollow interior with an inert gas to cause the molten material to flow into the casting mold through the nozzle.
A method of transferring a molten material to a casting mold, the method comprising:
- lowering a ladle into a source of molten material using a mechanical or a robotic handling device, the ladle having a hollow interior and an aperture facilitating flow into the hollow interior;
- filling the interior of the ladle with the molten material through the aperture;
- introducing an inert gas into a portion of a nozzle;
- removing the ladle from the source of molten material using the mechanical or the robotic handling device;
- causing the nozzle to contact a casting mold;
- and
- pressurizing the hollow interior with an inert gas to cause the molten material to flow into the casting mold through the nozzle.
