基于ProCAST本体件熔模铸造工艺优化设计

Optimization Design of Investment Casting Process for Entity Parts Based on ProCAST

利用ProCAST软件对铝合金本体铸件熔模铸造工艺进行了数值模拟,预测了铸件侧壁会有缺陷产生,对缺陷产生原因进行了分析并提出了优化方案。对优化后工艺方案再次进行数值模拟,解决了铸件疏松缺陷问题,并实际投产获得了合格铸件,验证了优化后工艺方案的可行性。

The investment casting process of aluminum alloy entity casting was numerically simulated by using of ProCAST software.The defects on the side wall of the casting were predicted,the causes of the defects were analyzed,and an optimization scheme was proposed.Then the optimized process scheme was numerically simulated again.The results showed that the problem of casting porosity was solved,and qualified castings were obtained in actual production,which verified the feasibility of the optimized process scheme.
