摘要

解决铸件热节缩孔尤其是远离冒口的热节缩孔

有效的办法是设计冒口补贴。但冒口补贴不仅增加了金属液的用量还会造成铸件力学性能下降。清除冒口补贴会使铸件表面质量变差又浪费大量工时。通过试验

对于精铸螺母用型壳外岩棉补贴代替冒口补贴取得了良好效果

使该精铸件的缩孔、缩松废品率由100%降到了4%以下

缩孔废品率由28%降到了0。

Abstract

To solve the casting shrinkage hole especially hot spot away from riser shrinkage

it is an effective way to design riser subsidies.However

the riser subsidies not only increases the metal liquid weight but also decrease mechanical properties.In addition

removal of riser subsidies can deteriorate casting surface quality and waste a lot of time as well as difficult to design riser subsidies on some parts.Through experiment

rockwool subsidies instead of riser subsidies for shell of nut exhibits acceptable effects

which decreased keyhole rejects from 100% to 4% and the shrinkage rate of waste from 28% to 0.
