Titanium alloy precision casting technology applications

With the progress of science and technology, titanium casting technology is more and more mature, terbium alloy's excellent performance has been widely recognized. Titanium casting quality continues to improve, manufacturing costs gradually reduced, so aviation, aerospace, marine and chemical industries have begun to use a large number of titanium castings, titanium alloy investment casting technology has been more and more widely used.

Application in the aerospace industry

From the 1990s onwards, on the new aircraft stay piece j r many large complex thin-walled whole casting of titanium table gold shaped structural parts. Airbus A380 aircraft with titanium amount of 45I a 65t / frame. The amount of titanium used in Duoyin aircraft accounted for its total weight of l 5 % 17%. F22 fighter fuselage structure with titanium 361/long lance, which includes a large number of titanium alloy castings alloy casting technology development adapted to the aircraft and the engine components required to reduce the weight of raw materials, high utilization rate, low processing costs, the demand for a short manufacturing cycle.

In foreign countries, aviation engines have been widely used in large-scale complex whole titanium alloy precision casting of the fan magazine and intermediary magazine and other large components. Successfully developed a F a 100, CFM a 56, CF6-80, F a 119 aircraft engines, such as large thin bib whole titanium box intermediary magazine, fan magazine, high-pressure pressurized machine magazine and other castings, the large diameter has reached 1300mm or so, the small wall thickness of less than 3ram, dimensional accuracy of the CT6 a cT7 level, metallurgical quality is high. The successful development of these precision castings, greatly improving the performance of the engine, reducing the weight of the aircraft. Improved material utilization, shorten the parts manufacturing cycle, reduce the manufacturing cost of aircraft engines.

U.S. F-22 aircraft using more than 70 titanium alloy castings, 50% of the wing is composed of titanium table gold castings. The use of precision casting of titanium alloy parts: rudder drive bracket, shielding plate, wing sidewalls before and after the mount, aileron backplane, air intake oblique frame and other six large structural parts.

Improve the rigidity of the parts, reduce the development cost. In the v a 22 aircraft used in the overall cast titanium gold transfer adapter. It is the original 43 small parts and 536 fasteners composed of aluminum forgings, changed to the whole cast titanium alloy, so that the entire aircraft manufacturing costs reduced by 30%, processing and installation time reduced by 62%, greatly reducing the manufacturing cycle.
