Abstract: This paper introduces the classification, working principle and characteristics of vacuum fine grain casting furnace used for producing aero-castings. It emphatically analyzesthe structure style and the core technology for fine grain casting furnace and double-properties casting furnace.Finally, it prospects the future development of domestic vacuum fine crystal (double-properties) casting furnace.

Key words: precision casting, fine grain casting, double-properties turbine wheel
