铸体冷缩
The numerical simulation of temperature field and shrinkage defect prediction for a valve casting, which was involved in 4 kinds of casting processes, were carried out. The good agreement has been obtained between the numerical simulation and the experimental result verification.
对采用4种不同铸造工艺方案的阀体铸件凝固过程进行了数值模拟及缺陷预测,获得了与试验相一致的模拟结果。
A new multifunctional device for testing linear shrinkage, stress and heat check of casting alloy easily and quickly is developed in the paper.
