摘要
研究了实型铸造干砂对垂直n型孔的充填性能．实验了主要工艺因素，如孔径、孔口深度、干砂粒形、振动方向、振动维数、振动频率、振动加速度等对其充填高度的影响．
The fill of dry sand for vertical n type pipe in full mold process is studied. The effect of the main tech-nological iactors,such as the diameter of pipe,the fill position of pipe,sand type,vibrating direction,vibrating dimen-sLon,vibrating frequency,and vibrating acceleration,on the fill height are tested.
