A method for casting a cast part according to the tilt pouring principle includes pouring a molten metal from at least one tiltable casting vessel into a casting mold including a mold cavity which forms the cast part. The molten metal is ladled directly out of a bale-out furnace using the casting vessel, and a metal oxide skin forms in the casting vessel on the surface of the molten metal. The casting vessel containing the molten metal and the metal oxide skin floating thereon is brought to the casting mold. The molten metal is poured from the casting vessel into the casting mold by a common rotation of the casting vessel and casting mold about an axis of rotation. The metal oxide skin rises to the top of the molten metal during the pouring process, floating predominantly on top and on the surface of the molten metal.

A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).

A process in direct chill casting wherein molten metal is introduced into a casting mold and cooled by impingement of a liquid coolant on solidifying metal in a casting pit including a movable platen and an occurrence of a bleed-out or run-out is detected the process including exhausting generated gas from the casting pit; and introducing an inert gas into the casting pit, the inert gas having a density less than a density of air; reducing any flow of the liquid coolant.

An example insulation enclosure includes a support structure having at least an inner frame and providing a top end, a bottom end, and an opening defined in the bottom end for receiving a mold within an interior of the support structure, and a radiant barrier positioned within the interior of the support structure, the radiant barrier including a front surface arranged to face the mold and a back surface facing the support structure, wherein the radiant barrier interposes the mold and the support structure to redirect thermal energy radiated from the mold back towards the mold.

In a continuous casting apparatus 100 for casting a stainless steel billet 3c, a long nozzle 2 extending into a tundish 101 is provided at a ladle 1 for pouring a molten stainless steel 3 in the ladle 1 into the tundish 101. Further, a nitrogen gas 4 is supplied as a seal gas around the molten stainless steel 3 in the tundish 101, and continuous casting of the stainless steel billet 3c is performed, in which, while immersing the spout 2a of the long nozzle 2 into the molten stainless steel 3 in the tundish 101, the molten stainless steel 3 is poured through the long nozzle 2 into the tundish 101 and the molten stainless steel 3 in the tundish 101 is poured into a casting mold 105.

A system for two stage casting of a metal alloy is disclosed that dispenses multiple feedstock metals into an arc melting crucible via a pressurized inert gas or metal vapor chamber to lower the volatilization rate of metals in an arc melting crucible at a rate proportional to the composition of the final desired alloy. The melt from the melting crucible enters a second stage cold wall crucible through a passage, where the melt cools and solidifies. A casting piston is used to slowly and progressively withdraw the solidified alloy from the cold wall crucible as it cools.

The present invention relates to the process for enhancement of thermal conductivity property of aluminium up to 50 to 90% or more by doping graphene or reduced graphene of two to five layers into aluminium by melting and casting process under inert or vacuum or atmospheric condition using salt and flux. Graphene with purity of 70 to 90% was incorporated into aluminium of any form for 30 to 120 minutes under inert atmosphere or vacuum at 700-900 deg C. Graphene of 0.1 to 5% weight of the total weight of aluminium has been used in the process. Under optimum conditions enhancement of thermal conductivity up to 80 to 90% has been observed using this process.
