Numerical simulation of meniscus in induction solidified shell melting

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 1000 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.
