基于MAGMASOFT的大型铝合金叶轮铸造工艺模拟

doi:10.3976/j.issn.1002-4026.2018.04.008

Abstract

Abstract:

A sand casting process scheme for large aluminum alloy impeller casting was designed in this paper. By using the casting simulation software MAGMASOFT, the filling process, the distribution of the gas defects and the temperature field distribution of the casting were simulated. According to the analysis, the main reason for the defects of the castings was the unreasonable design of the riser at the mouth ring. It is proposed to add insulation sleeve to the riser at the mouth ring to increase the feeding effect of the riser. The simulation results show that the problems of shrinkage porosity and shrinkage tendency of castings are effectively solved after optimizing the process.

Key words: MAGMASOFT, numerical simulation, process optimization, impeller
