摘　　要：为了解不同材质冷铁对铸铁件硬度的影响规律,分别使用铸铁、石墨、钢三种冷铁,在传热条件相同时,对灰铸铁与球墨铸铁铸件同一部位进行激冷,并对其硬度进行检测。测试结果表明,不同材质的冷铁对相同材质铸件硬度的影响不一致。The influence of different materials of cold iron on the hardness of cast iron was studied.Under the same heat transfer conditions,three kinds of cold iron,graphite and steel were used respectively to chill the same part of gray cast iron and ductile cast iron,and their hardness was tested.The test results show that the influence of different materials on the hardness of castings of the same material is inconsistent.
