摘　　要：通过向Cu-10Sn合金中加入1%的Cu2O颗粒制备了含有SnxOy合金的材料,随后利用高频磁场的电磁分离技术成功将铜合金中的氧化物夹杂分离到分离器边缘。研究了分离器直径、磁感应强度、分离时间对分离效果的影响。试验结果表明,当分离器直径为12mm,磁感应强度为60mT,分离时间为60s时,氧化物夹杂的分离效果最好。SnxOy oxide inclusions were successfully separated from the Cu-10%Sn alloy with 1% Cu2O addition under the high frequency magnetic field. Influences of separating tube diameter, magnetic induction intensity and separating time on separation efficiency were investigated. The experimental results indicate that the desirable separation efficiency of oxide inclusions can be obtained for 60 s with the separating tube diameter of 12 mm and the magnetic induction intensity of 60 mT.
