Benefits of technology

[0010]Utilizing the two chamber casting system, one of the primary tenets is the use of a pressure differential in order to assist the evacuation of material from the crucible into the pattern mold. In order to truly optimize the filling of complex geometries, the physical properties of resulting parts, and the efficiency of the equipment, it is beneficial to vary the pressure differential utilized during the casting sequence. Optimally, the beginning of the cycle will have a minimal pressure differential between the outer chamber (containing

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 tim

Embodiment Construction

[0037]As shown in FIG. 1, a unit cell titanium casting system 5 comprises an external container 44, an internal container 39, a vacuum mechanism 60, a crucible 10, an induction coil 15, a coil electrical generation mechanism 25, and a mold 30. The external container 44 defines an external chamber 45. The internal container 39 defines an internal chamber 40. The vacuum mechanism 60 includes a vacuum line 71, a vacuum connector 70 and pressure gauges 75a and 75b. The vacuum mechanism 60 is utilized to evacuate and pressurize the external chamber 45 and the internal chamber 40 in order to create a pressure differential between the internal chamber 40 and the external chamber 45.

[0038]The crucible 10 is preferably composed of a ceramic material. In a most preferred embodiment, the crucible 10 is composed of a first layer 11a, a second layer 11b and a silica based third layer 11c, as shown in FIG. 7. A metal ingot 20 is placed within the interior of the crucible 10. The metal ingot 20 is...

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

CROSS REFERENCES TO RELATED APPLICATIONS[0001]The present application claims priority to U.S. Provisional Patent Application No. 62 / 354,003, filed on Jun. 23, 2016, which is hereby incorporated by reference in its entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTIONField of the Invention[0003]The present invention relates to precision titanium casting. More specifically, the present invention relates to an apparatus and method for precision titanium casting utilizing induction heating.Description of the Related Art[0004]Various methods of titanium casting are well-known. One such method is investment casting which involves a lost wax procedure.[0005]Vacuum electric arc smelting is another method in which a titanium ingot is melted by substantial heat generated by mutual discharging in a high current state by respectively using a titanium ingot crucible and a water-cooled copper crucible as a positive electrode and a ...
