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

As the electromagnetic stirrers are commonly implemented in the continuous casting process of a steel mill, for enhancing the on-site controllability and productivity, it is convincible that detailed assessments about the three-dimensional characteristics of such equipments at different physical environments and material properties must 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 the system structures and input driving sources. Based on thorough three-dimensional steady-state and dynamic analyzing results, this paper will provide the summarized guidance for operations and designs of the in-mold electromagnetic stirrer for metal industry applications.
