摘要
分析了不锈钢复杂防腐蚀壳体铸件的结构特点,对其进行铸造工艺设计。设计了两种不同浇注系统,对比分析铸件的流场、温度场、缩松缺陷分布及位移场。通过模拟分析,研究熔体的流动及铸件的凝固顺序,减少缩松缩孔缺陷和尺寸收缩变形。借助数值模拟方法缩短产品试制周期,降低生产成本,控制铸件品质,达到提高铸造生产的经济效益和产品的竞争能力的目的。
The casting process was designed based on analysis of the structure characteristics of the stainless steel complex anti-corrosion shell castings. Two kinds of gating systems were determined. The flow field and temperature field, the shrinkage defect distribution and displacement field were used for comparative analysis. Through simulation analysis, the gating system was optimized. The flow and solidification sequence of melt casting was studied. The shrinkage defects and dimensional shrinkage deformation were reduced. The numerical simulation method can shorten the product development cycle, reduce production cost, control the quality of castings, and improve the economic benefits.
