Abstract: With the continuous development of China's commercial aviation engine industry, the demand for large-sized casing castings is increased. Facing the complex international environment, large vacuum induction precision casting furnaces, as the core equipment for producing large-sized casings, must break free from import dependence. This article first conducts an in-depth analysis of the market situation and technological status of large-scale vacuum precision casting furnaces. Then the technical characteristics of the domestically produced new large-scale vacuum precision casting furnace and the comparison with foreign products are introduced. Finally, a brief analysis is conducted on the future development prospects of the large vacuum precision casting furnace.

Key words: casing, large casting, precision casting, vacuum induction furnace, aircraft engine
