| 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... |
