The magnetic field interference in dual-ingot low frequency electromagnetic continuous casting

摘要：

　　The magnetic field interference was studied by numerical simulation and experimental examination during dual-ingot low-frequency electromagnetic casting process.By using ANSYS software package to mesh and compute,the magnetic field distribution of semi-continuous casting mold region was simulated.The calculated results were verified with the experimental ones and the effects of current direction,shield,silicon sheet and the coil distance on the distribution of magnetic field and ingot were observed.The result indicated that: regardless of current direction,the magnetic field interference among coils appears and the magnetic flux density weakens in the neighbor part of coils.When the current direction of adjacent coils is opposite,the magnetic intensity in ingots is stronger than that of in the same direction.As the distance between coils increases,the magnetic field reduction generated by interference decreases.The magnetic field interference can be alleviated by setting silicon steel sheets or shield.
