摘　　要：为准确计算打箱时间,避免铸件产生缺陷和提高生产效率,采用热电偶对铸件从浇注到最后凝固的温度进行测量,绘制了铸件降温曲线,得到了不同重量灰铁铸件的砂箱移动时间及打箱时间。根据该曲线进一步对生产工艺进行调整,从而使铸件质量得到保证。The temperatures from casting pouring to solidification were tested by using of hot heat electric couple, and the cooling curve was drew in order to calculate shakeout time, prevent defect and increase production efficiency. Moving and shakeout flask time of different weight grey cast iron were obtained. The quality of castings meet requirement by adjusting process on the basis of the cooling curve of the castings.

关 键 词：测温 降温曲线 打箱时间
