摘要：
Effects of processing variables such as frequency of imposed magnetic field, imposed magnetic flux density, processing time, diameter of inclusions, and value of r 1/δ on the electromagnetic separating(EMS) removal efficiency were analyzed theoretically. The higher the frequency, the wider the range of r 1/δ will be. Removal efficiency reaches the maximum while r 1/δ ranges from 1.5 to 2. And the experimental results on aluminum melt show that higher frequency and magnetic flux density make for higher removal efficiency, matching well with the theoretical results. When f is 15.6 kHz, B e is 0.1 T , and imposed time is 10 s, more than 80% inclusion particles with 6 μm diameter can be removed.
