Electromagnetic Control of the Meniscus Shape during Casting in a High-frequency Magnetic Field

In cooperation with the Process Technology Research Laboratories,
Nippon Steel Corporation, (Dr. E. Takeuchi
and Dr. T.Toh)

·       The meniscus of a Sn-10%Pb charge inside a Cold Crucible device was shaped utilising a high frequency electromagnetic field.

·       The equilibrium shape and stability of the meniscus was experimentally measured and compared with the predicted results from the mathematical model.
