摘要
为解决复杂铸件内孔结构加工后缩松问题,设计了石墨复合内冷铁。利用外部石墨材料的良好导热性将与之直接接触金属液的热量传导给中间密度高、总体储热量大的金属材料。其整体蓄热能力不低于金属冷铁,且可清理掉石墨,冷铁不随铸件进入加工工序,不会出现加工时打刀现象。另外中间的金属材料可以重复利用,降低使用成本。
To solve the shrinkage porosity problem of complex casting inner hole,the composite inner chiller was designed.The high thermal conductivity of the external graphite material is used to conduct the heat of the liquid metal to the metal chiller with high density and high heat storage.The heat storage capacity of graphite inner chiller is not lower than that of metal inner chiller,and the graphite can be cleaned up,so the chiller will not follow the casting to the machining process and destroy the tool.In addition,the metal materials in the middle can be reused to reduce the use cost.
