On Top Riser Working
Journal Title: RECENT - Year 2015, Vol 16, Issue 46
Abstract
In the case of castings that have a hotspot at the, top riser are normally used in industrial practice. It is envisaged that the hotspot is very close to the riser. It is considered that the liquid alloy flows more easily from riser in the casting. The paper shows that this view is wrong. Is analyzed by computer simulation, the part solidification with top riser and with lateral riser. The results show that for the same riser size, the top riser assure not shrinkage elimination inside the casting, while in the case of lateral is obtained the casting without shrinkage.
