Melting reactive metals and alloys, such as titanium, poses a significant challenge due to the risk of crucible damage and contamination of the molten material. Full levitation melting presents a promising solution; however, its application has largely been limited to small laboratory samples. This paper introduces a methodology for modeling (in a 2D axisymmetric domain) and optimizing a new large-scale levitation melting system and demonstrates its application to pure titanium. The system features a torus-shaped load positioned within a gutter-shaped coil. Numerical experiments using this approach confirm the feasibility of stable levitation for a substantial mass (2.6 kg) within a newly designed electromagnetic levitation system.
熔化诸如钛之类的活性金属和合金，由于存在坩埚损坏和熔融材料污染的风险，是一项重大挑战。完全悬浮熔炼是一个很有前景的解决方案；然而，其应用在很大程度上仅限于小型实验室样品。本文介绍了一种在二维轴对称域中对新型大规模悬浮熔炼系统进行建模和优化的方法，并展示了其在纯钛上的应用。该系统的特点是在槽形线圈内放置一个环形负载。使用这种方法进行的数值实验证实了在新设计的电磁悬浮系统中对相当大质量（2.6千克）进行稳定悬浮的可行性。
