Three-Dimensional Design and Performance Assessments of a Linear Induction-Type Electromagnetic Stirrer

Electromagnetic stirrers are commonly implemented in the continuous casting process of a steel mill. To enhance their on-site controllability and productivity, it is desired that detailed assessments about the 3-D characteristics of such equipment at different physical environments and material properties can be performed in the design stage. Since the stirrer system is mainly constructed based on the principles of linear induction machines, variations of the generated electromagnetic forces and magnetic fields will be highly affected by system structures and input driving sources. Based on thorough 3-D steady-state and dynamic analyzing results, this paper provides the summarized guidance for operations and designs of in-mold electromagnetic stirrer for metal industry applications.
