Abstract
Techniques and apparatus for electromagnetically stirring a melt material are disclosed. In accordance with some embodiments, the system may include a containment vessel within which a melt material may be disposed. The melt material may include, for example, an electrically conductive alloy, which optionally may be non-ferromagnetic and/or glass-forming. In its molten state, the melt material may have alternating current (AC) applied directly thereto while being immersed in a magnetic field, which may be static or dynamic, depending on the desired stirring effect. Application of the AC and magnetic field may continue as the melt material cools and solidifies, the sinusoidal nature of the AC and the Lorentz force of the magnetic field providing convective motion which tends to agitate the molten melt material in a manner which may realize an improvement in heat transfer and chemical homogeneity of the resultant cast solid.
