Electromagnetic Stirring - an overview | ScienceDirect Topics
The electromagnetic stirring (EMS) technique has been applied to SSM to produce a high fluid stirring velocity in the semisolid materials. The basic concept of this process is that strong electromagnetic fields induce electrical currents in a moving conductive fluid, which in turn creates forces on the fluid.

1991年5月1日 · It is well known that an alternating magnetic field (either single phase or multiphase) applied to a conductor, whether solid or fluid, will induce electric currents in the conductor, and hence a Lorentz force distribution. This Lorentz force is in general rotational, and if the conductor is fluid, it is set in motion.

2024年2月1日 · Electromagnetic Stirring: An electromagnetic field induces stirring in molten metal to enhance its flow and uniformity. This technique reduces slab defects like porosity and segregation, thus improving slab quality.
In addition to the proper tuning of the casting parameters (temperature, velocity, primary and secondary cooling rate) electromagnetic stirring (EMS) is another instrument to achieve an enhanced quality. EMS promotes the columnar to equiaxed transition, reduces segregation and improves the surface quality.
