Experiment and Production of Heavy Thick-walled Winding Barrel Casting for Crane with Spheroidal Graphite Cast Iron

大型 厚 壁球墨铸铁起重机卷筒 铸件的试验与生产

Causes and resolutions for crack on thick-walled casting

厚 壁 铸件裂纹成因及解决办法

Complicated thin-walled castings require an upper limit magnitude ( e.g. pouring temperature 750 ℃) and simple thick-walled casting should use lower limited magnitude . The physical feature and genesis of typical casting defects of LP-EPC process for magnesium castings were investigated .

复杂薄壁铸件一般选择工艺参数值的上限（如：浇注温度750℃等），简单 厚 壁 铸件可以选择工艺参数值下限。分析了镁合金真空低压消失模铸件中典型缺陷的物理特征及形成原因。
