摘　　要：介绍了硫氧随流孕育剂在乘用车球铁飞轮上的应用,其原理是利用硫氧随流孕育剂增加形核能力使铸件单位面积析出的石墨球数量变的更多,石墨球变的更小,并在不采用发热冒口的情况下做到了较小的缩松面积,解决了加工面缩松缺陷问题,满足了客户的需求。It introduces the application of sulfur & oxygen contained stream inoculant on ductile iron flywheel.Adding sulfur & oxygen contained stream inoculant will increase graphite nodules in a unit area, also it will make graphite nodule smaller. In this case, we can narrow porosity area without using heat feeder, which can solve porosity issue on machining surface so as to meet requirement of our customer.
