Abstract:The magnetic field distribution in the improved electromagnetic
   continuous casting aluminum-made mould through adding silicon steel
   sheet was measured. Using the mould 7050 aluminum alloy slabs were
   prepared by soft-contact electromagnetic continuous casting. The
   solidification structure and solute distribution of the slabs were
   investigated. The results show that the magnetic field in the improved
   mould was significantly enhanced. At the same height, the magnetic
   induction intensity in the mould reached maximum at the corner, took
   second place at the center of short side with the value a little
   stronger than that at the long side, and reached minimum at the center
   of the plane. The magnetic induction intensity in the mould basically
   reached maximum at the half of the induction coil height. The
   solidification structure of the slabs prepared by the improved mould was
   significantly refined, and the macro-segregation of the solute elements
   was effectively restrained
