概要： 在模内电磁搅拌（EMS）中，通过洛伦兹力产生水平流动，从而避免非金属夹杂物的夹带。尽管EMS效应受到许多报道的欢迎，但关于水平流下凝固壳附近非金属夹杂物行为的研究却很少。在本研究中，利用水和离子交换树脂颗粒进行模型实验，分析凝固壳附近的非金属夹杂物与水平流体的行为之间的关系。模型实验结果表明，避免非金属夹杂物卷入的主要因素是水平流给予的力，萨夫曼力的影响可以忽略不计。
Synopsis : In in-mold electromagnetic stirring (EMS) , horizontal flow is generated by Lorenz force so that non-metallic inclusion entrapment is avoided. Though the effect of EMS is popular by many reports, there are few studies about the behavior of non-metallic inclusions near solidfied shell under horizontal flow. In this study, a model experiment using water and particles made of ion-exchange resin is performed to analyze relations between behavior of non-metallic inclusions near solidified shell and horizontal fluid. As a result of the model experiment, it is cleared that the main factor avoiding non -metallic inclusion entrapment is the force given by the horizontal flow and that influence of Saffman force can be negligible.
