Abstract

In order to simulate the casting process of a typical aluminum alloy, a 3 D entity model for a pouring system was used for numerical analysis of the filling and solidification process with ProCAST software. A comprehensive analysis including the change of temperature field, the velocity of filling, the solid phase as well as the location of casting defect, showed that the defects such as shrinkage (cavity) porosity can be reduced effectively with an increase in the mold preheating temperature and the number of vents. This simulation also serves as a theoretical reference for the sake of facilitating casting quality.

基于ProCAST FEA程序的金属型低压铸造技术及成形工艺分析

摘要

为了模拟典型铝合金的铸造过程，采用ProCAST软件，采用浇注系统的3D实体模型对充填凝固过程进行数值分析。综合分析温度场变化、充型速度、固相以及铸造缺陷的位置，表明随着模具预热温度的升高，缩孔（型腔）气孔等缺陷可以有效减少。和通风口的数量。为了提高铸件质量，该模拟也可作为理论参考。
