Abstract

ZL114Aoil circuit shell casting was produced by the low pressure casting.Effects of the optimization of composition

grain refinement and melt treatment of ZL114 Aon the microstructure and mechanical properties of the shell casting were investigated.Furthermore

The processing parameters of low pressure casting and solidification process were simulated by the ProCAST software.The results show that

by using high purity raw material

alloy composition optimization

refinement of the alloy and melt purification treatment

the performance of ZL114 Aalloy is increases greatly.Slot gating system and thick area placed chill can improve the internal quality obviously of the shell casting with decreasing shrinkage porosities.
