Description

technical field [0001] The invention belongs to the field of nonferrous metal material processing, and in particular relates to an electromagnetic casting method with a phase difference traveling wave magnetic field. Background technique [0002] With the continuous development of casting technology, people's requirements for casting quality have been continuously improved, and stricter standards have been put forward for the structure and properties of metals and alloys. The performance of casting alloys mainly depends on their solidification structure, and ordinary casting alloys have solidification structures. The shortcomings of developed dendrites, coarse grains, and uneven structure greatly reduce the mechanical properties and deformation capacity of the material; according to the Hall-Petch relationship, refining the grains can improve the mechanical properties of polycrystalline materials. Strength; therefore, it is of great significance to refine the grains in the m...
