关于铝的连续电磁的纯化的一个新奇计划融化基于一根方形的分离管子和 50 Hz 交流电(流) 的利用被提出生产电磁的力量。与电流 of400 A/cm~2,把 95% 包括从铝移开拿仅仅 10 s,这试验性地被发现融化。Comprehensivenumerical 模拟被执行在这个过程后面调查动力学机制。结果证明包括的移动被归因于电磁的快活和有包括和电流的尺寸的有效增加强加了的旋转电磁的力量,和移动导致的第二等的流动的合作效果。分发和包括的移动效率上的理论预言被实验支持。
A novel scheme about the continuous electromagnetic purification of aluminum melt was put forward based on the utilization of a square separation pipe and a 50 Hz alternating current to produce electromagnetic force. It is experimentally found that with electrical current of 400 A/cm^2, it takes only 10 s to remove 95% inclusion from aluminum melt. Comprehensive numerical simulations were carried out to investigate the dynamics mechanisms behind the process. The results show that the removal of inclusion is attributed to the cooperative effects of electromagnetic buoyancy and the secondary flow induced by the rotational electromagnetic force, and the removal efficient increases with the size of inclusion and the electrical current imposed. Theoretical predictions on the distribution and removal efficiency of inclusion were supported by the experiments.
