Jiadong Shen, Boming Xu

Abstract


In view of the defects such as shrinkage porosity, shrinkage cavity and uneven grain size in the casting process of aluminum alloy piston, the numerical simulation of ZL108 aluminum alloy piston casting process was carried out by using Procast professional casting finite element analysis software. The three process parameters of pouring temperature, pouring speed and mold temperature were investigated by orthogonal test method, and the grain size and comprehensive scores of shrinkage porosity, shrinkage cavity distribution and mold filling rate. The results show that the optimal combination of process parameters is the pouring temperature of 700 ℃, the pouring speed of 0.3 kg/s and the mold temperature of 150 ℃. The numerical simulation of ZL108 aluminum alloy piston casting process provides theoretical guidance for the casting of important and complex parts with uneven wall thickness, and reduces the cost and time of part process optimization design
