Electromagnetic Stirring Systems

Electromagnetic stirring (EMS) systems have been extensively used in the continuous casting process in steel-making industries to produce high-quality steel products. Although the operational principles of such EMS facilities are well established and extensively applied, demonstrations of actual stirring effects on molten metal are always desired for comparative investigations. To fulfill the requirements for investigating EMS phenomena, a hot-mode experimental apparatus of an EMS system with liquid zinc (Zn) as the test object has been successfully established in the laboratory. The performances of the experimental apparatus are further confirmed by detailed three-dimensional (3-D) finite element analyses (FEA). With such a well-constructed appliance, the relative behaviors at various operational conditions can be thoroughly investigated, and the characteristics of such EMS facilities can be easily realized.
