摘要
采用正交设计现场浇注，试验研究了铸钢件冒口离开热节动态补缩特性．结果表明，冒口位置对补缩效果影响显著，铸钢件冒口在离开铸件的几何热节处，实施动态顺序凝固补缩，提高了冒口补缩效率和工艺出品率．在试验条件下，冒口离开几何热节的距离为一倍热节圆直径时。
With the help of orthogonal experiment design and in situ pouring tests the dynamic feeding character of riser being away from hot spot of steel casting is studied The results show that the influence of riser position on feeding is noticeable Under the test coditions, when the distance between riser and geometry hot spot of casting is equal to hot spot diameter,casting quality is better Acoording to the technical principle the dynamic directional solidification feeding efficiency of riser and steel casting yield could be promoted
