基于ProCAST的拉伸试棒的金属型铸造工艺分析

Analysis of Permanent Mold Casting Tensile Testing Bar Based on ProCAST Software

使用ProCAST软件,对铝合金金属型铸造拉伸试棒的充型和凝固过程进行数值模拟,在验证ProCAST模拟结果准确的基础上,分析充型凝固过程的各种物理场,确定浇注系统的合理性。试验结果表明,该浇注系统可以减少铸造缺陷,使铸造出的拉伸试棒的力学性能能够接近真实值。

Filling and solidification process of permanent mold casting Mg or Al alloy tensile testing bar were simulated by the ProCAST software to understand various physical field and to optimize gating system design. The simulated results are well in agreement with experimental ones. The results verify that the optimized gating system can effectively eliminate casting defects in the testing bar so that mechanical properties of the permanent mold casting bar are nearly the true value.
