摘要
采用数值模拟技术对球铁铸件壳体的铸造工艺进行分析优化,通过对其凝固过程和缩松、缩孔分布趋势的分析,优化了铸造工艺。通过模拟分析后发现,在内浇道内侧安放冷铁可有效解决铸造缺陷问题。实验证明,模拟仿真结果与实验结果相一致。
The ductile iron casting process was analyzed and optimized based on numerical simulation. The solidfication process and the distribution of shrinkage in the castings were analyzed. The casting process was optimized. Adding chills at the ingate can solve the problem. By experiment, the results of simulation and experiment are the same.
