摘　　要：运用铸造数值模拟软件Pro CAST,对DF-300A减速机箱体的铸造工艺方案进行充型和凝固过程的数值模拟,分析铸件充型和凝固的状态以及温度场的变化情况。针对温度对阶梯式浇注工艺方案的充型和凝固过程的影响进行数值模拟,根据分析结果对箱体的铸造方案进行优化改进并确定最优浇注温度为1 400℃。通过增加冒口尺寸及数量、增加冷铁、改变铸件的圆角大小等方式有效地控制了缩孔、缩松缺陷的产生,提高了铸件品质和合格率。The filling and solidification process of the stepped gating system scheme for DF-300 A reducer box body was simulated by casting simulation software Pro CAST, and the state of casting filling and solidification and the changes of the temperature field of the castings were analyzed. Based on the simulation analysis results, the casting process scheme was optimized and improved, the optimal pouring temperature was determined, that is 1400 ℃. By increasing the size and the number of riser, increasing the size of cold iron, changing the casting rounded corners and other ways, the defects of shrinkage cavity and porosity were effectively controlled.
