| 摘 要： | 本文研究了高频磁场中熔体夹杂的迁移行为,利用感应线圈产生的高频磁场,选取Al-2%Fe、Al-5%Fe合金中的产生的富铁相作为研究对象。颗粒与熔体之间的导电率存在很大的差异,当外加磁场时,产生的电磁力作用于熔体,固相颗粒将向分离器外壁面迁移而除去。通过加入变质剂Mn元素研究其对富铁相形貌的影响,研究表明:在Mn/Fe的摩尔比为1.4～1.5时,针状的富铁相变成了块状或汉字状,减小富铁相再熔体中迁移受到的阻力,使之更利于在熔体中迁移,并进一步探讨了电磁分离过程中各工艺参数对夹杂颗粒迁移行为和实际分离效率的影响。

| Abstract: | In this paper,the migration behavior of melt inclusions under high frequency magnetic field was investigated,using the induction coil to generate a high-frequency magnetic field,the iron rich phase in Al-2%Fe,Al-5%Fe alloy was chosen as research object.Because of the different of conductivity between the melt and inclusions,electromagnetic force was generated in melt when magnetic field work,the for melt,the inclusions was migrated to the separator wall and removed.The influence of modifier Mn elements on i... |
