Electromagnetic Stirring - an overview | ScienceDirect Topics

Ken Mills, in Treatise on Process Metallurgy: Industrial Processes, 2014. 1.9.5.7.1 Electromagnetic Stirring. Electromagnetic stirring (EMS) is carried out with AC at 50 Hz with the electromagnetic effect penetrating through the volume. EMS is used to (i) remove inclusions and gas bubbles, (ii) homogenize the melt composition and temperature, and (iii) refine the microstructure.
