摘　　要：利用三维数字化测磁手段对半固态浆料制备用电磁搅拌器的磁场进行测量。结果发现,电磁搅拌器内部磁感应强度在100mT附近,磁感应强度沿搅拌器轴向及径向分布均匀,不同电磁搅拌电压、频率组合产生的搅拌磁场强度变化明显。Magnetic field measurement in semi-solid slurry electromagnetic stirrer by three-dimensional digital magnetic measurement method was carried out.The experimental results show that the magnetic induction in the electromagnetic stirrer is approximately 100 mT,and the magnetic induction is uniformly distributed along the axial and radial electromagnetic stirrer.The magnetic induction distribution exhibits the apparent changes with different combination of electromagnetic stirring voltage and frequency.
