摘　　要：提出了一种带C型铁芯线圈的铝合金电磁净化装置，通过定量金相分析了其净化效果，并应用有限元软件对其电磁场进行了仿真。结果表明，该装置能在气隙内产生0．01～0．03T的磁场，可满足电磁净化设备的磁场要求；铁芯使一部分磁力线沿着它形成了回路，增强了气隙中的磁场强度，而气隙的存在削弱了磁场强度。A new purification device with C-type iron core coil was proposed.Its purification effect was analyzed by the quantitative metallography,and the magnetic field was simulated with FE software.The results show that the device can produce magnetic value of 0.01-0.03T field in the air gap,which can meet the requirement of electromagnetic purification.The iron core makes a partial magnetic lines form circuit along iron core and enhance the magnetic field inside the gap,while the air gap itself weakens the magnetic field.
