Benefits of technology

The two chamber casting system uses a pressure difference to help evacuate material from the crucible to the pattern mold. To optimize the casting process, the pressure difference should be minimal at the beginning of the cycle and increased just before the crucible is emptied. This decreased pressure helps allow for smooth transition to complex geometries, minimizes turbulent flow of molten titanium, and reduces overall equipment cycle times.

Problems solved by technology

Vacuum induction smelting and vacuum electric arc smelting require the use of a water-cooled copper crucible which results in the loss of substantial heat.
Furthermore, the preparation of the molding shell is very complex and time consuming, which adds to the costs.
The molten titanium liquid will come into direct contact with water if the crucible cracks, resulting in a fierce reaction, or even explosion, which poses a great threat to production safety.

Embodiment Construction

[0037]During the casting process it is critical to ensure that the material be heated sufficiently and consistently in order to ensure proper flow into the pattern mold. Especially with the use of a bottom-fed / gravity flow system, having the ability to precisely control the pour time will allow for optimum material heating ensuring desired material properties in the finished part. In order to achieve this a chill plate should be utilized which would help to definitively control the time that the molten material would transition to the pattern mold. The chill plate would be in the shape of a ring, with an opening centered on the opening of the ceramic crucible where the material is being melted. The plate itself would be cooled during melting and then at the optimal pour time, the cooling would be turned off. With the cooling, the seal melts through and the material is evacuated into the pattern mold. The use of this feature will allow for precise evacuation times providing consisten...

Abstract

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).

Description
