Abstract：Large,complex structure of aluminium alloy base high quality demand of castings,using numerical simulation software ProCAST,large aluminum alloy base castings were numerically simulated to optimize the casting process.The results show that the casting system with 3 sprues and 12 ingates cannot obtain good large aluminum alloy base castings well,and there is often a large area of cold lap.The gating system with 4 sprues and 16 ingates can obtain good castings after adjustment.The optimum pouring temperature and pouring time of large aluminum alloy structure base are 730℃and 100 s.Under these conditions,the castings have good formability and excellent internal quality.
