| Abstract: | A type of counter-gravity casting equitment with fuzzy intelligent control was studied. It has excellent filling hydrodynamics and solidification condition. The complex thin wall A357 alloy castings were successfully produced by using the self-made counter-gravity casting equipment. The results indicated that the counter-gravity casting equipment can run well and be controlled reliably.Aluminum alloy thin-walled castings can be filled completely with grains fine and microstructure compact. The integration of microstructural control and precise forming was realized. |
