Electromagnetic casting

Definition

Electromagnetic casting is a process used to solidify molten metal into a desired shape by utilizing electromagnetic forces to control the movement and cooling of the metal. This technique enhances the quality and properties of the cast material by reducing defects and controlling the solidification process more effectively than traditional methods. By applying magnetic fields, it also improves the flow of molten metal and can achieve more uniform cooling rates, which is crucial in metallurgical processing.
