The effects of Amper·coil

slit numbers

alloy and coil position on meniscus height in induction solidified shell melting was simulated by a numerical model.The results reveal that the meniscus height linearly increases with increasing in Amper·coil value

where the meniscus height is increased by 4.2 mm with increasing 1 000 A·coil.Meanwhile

the meniscus height is proportional to slit numbers in the mold with the silt numbers less than 40

in which the meniscus height is increased by 0.6 mm with increasing one slit number

while it is slowly increased with increasing slit numbers when the slit number is more than 40.In addition

the meniscus height increases with the decrease of relative magnetic induction density of the alloy

and it is decreased with the increase of the alloy density.So the meniscus height of Ti-48Al-2Cr alloy melt is the highest in the three alloys.
