凝固模拟在球铁飞轮工艺优化上的应用

Application of Solidification Simulation in Technology Optimization of Ductile Iron Flywheel

应用MAGMAsoft对四种不同结构球铁飞轮的不同工艺方案进行凝固模拟,根据凝固模拟结果和实际试生产铸件外观缺陷及内部缩松情况,提出不同改进工艺方案并对其进行凝固模拟,选择最佳方案应用于生产。优化后的工艺方案投入批量生产,球铁飞轮的缩孔、缩松缺陷达到用户要求。

Solidification simulation has been on each of different technology of ductile iron flywheel of four different structures with the help of MAGMAsoft,of which results and appearance defects and inner shrinkage porosity of the real castings in trial production have been based upon to bring forward different technology improvements which have been simulated to select an optimal one that has been used in batch production,with defects meeting users' requirements.
