摘要
研究了在0Hz~50Hz范围下行波磁场作用下,圆柱型坩埚内铀金属熔体中的夹杂物运动迁移行为。模拟与实验结果表明,在下行波磁场作用下,熔体中夹杂物在圆柱型坩埚上部靠近磁场发生器处,具有明显的富集区域,下行波磁场对熔体中夹杂物具有净化作用。
Under the action of downward wave magnetic field in the range of 0Hz~50Hz, the movement and migration behavior of inclusions in uranium metal melt in cylindrical crucible were studied. The simulation and experimental results show that under the action of the traveling magnetic field, the inclusions in the melt are concentrated in the upper part of the cylindrical crucible near the magnetic field generator, and the downward wave magnetic field can purify the inclusions in the melt.
