利用高频磁场分离Al熔体中的非金属夹杂
, PP. 405-410
Keywords: 高频磁场,Al熔体,非金属夹杂,分离
Abstract:
对利用高频磁场分离静置Al熔体中非金属夹杂的工艺参数进行了研究.通过理论解析计算得出频率f,磁感应强度Be,颗粒直径dp,电磁力作用时间t,管径与集肤深度的比值γ1/δ等参数与夹杂分离效率η的关系,并与实测分离效率进行了分析和比较.实验结果表明,较高的磁场频率和磁感应强度是高分离效率的保证,对于粒径为6μm的非金属夹杂,磁场频率为15.6kHz,磁感应强度为0.1T时,电磁作用10s即可获得80%以上的夹杂分离效率;r1/δ值的影响与频率有关,频率越高,则r1/δ的取值范围越宽;r1/δ=1.5-2时可使分离效率获得最大值.
