Through technical breakthrough, the company has solved a series of technical problems in the production of high-temperature alloy investment castings such as large-size thin-walled castings and complex special-shaped structure castings in the development process of several models of high-temperature alloy investment castings for gas turbines, and has broken through a series of key technologies. The development and production of superalloy investment castings can completely meet the needs of end users. The company adopts the technology of thermal control solidification to produce complex thin-walled superalloy castings. Through precise assembly design and production, the wax pattern can be pressed separately, and the size of wax pattern can be ensured by precise positioning and combination. The design scheme of split ceramic core and a variety of accurate detection methods are used to realize the integral casting of high-temperature alloy with complex cavity structure and ensure the metallurgical quality of the castings and dimensional accuracy.
