摘　　要：针对中大型往复泵泵盖铸件在生产过程中出现的缩松、缩孔等缺陷,利用AnyCasting铸造模拟软件对原工艺方案进行了凝固过程的模拟以及缺陷预测。结合缩孔缩松形成机理,分析了铸件产生缺陷的原因,并对原工艺方案进行了优化。采用优化后的原工艺方案能获得质量合格的铸件,但工艺出品率仅为45%。为获得质量合格的铸件,同时提高铸件工艺出品率,设计了新的工艺方案,通过对新工艺方案的模拟优化,铸件的工艺出品率提高到62%,达到了节能减材的目的,提高了企业的生产效益。In view of the defects such as shrinkage cavity and shrinkage porosity appeared in production process of Medium and Large pump cover casting,the solidification process and defects prediction were simulated of the original process scheme by using AnyCasting software.Combined with shrinkage cavity and porosity formation mechanism,the causes of defects in casting were analyzed,then the original process scheme was optimized.The casting with qualified quality can be obtained by using the optimized original process scheme,but the process yield was lower as 45%.In order to obtain qualified castings and improve the casting process yield,a new process plan was designed.Through the simulation and optimization of the new process plan,the casting process yield was increased to 62%,which achieved the purpose of energy saving and material reduction and improved the production efficiency of the enterprise.
