Electrode Induction Melting Inert Gas Atomization (EIGA) is the state-of-the-art process for the high-quality spherical powder production for additive manufacturing needs. The growing demand for EIGA powders drives the interest for the scale-up of well-established atomization of small Ø50 mm Ti-6Al-4V electrodes, as well as atomization of new refractory materials like Tantalum. However, during first tests with Ø150 mm Ti-6Al-4V and Ø50 mm Tantalum electrodes, the difficulties with melting stability were observed. In order to overcome these difficulties and to improve understanding of details of inductive coupling and favorable melting conditions, a numerical model for the electrode induction melting has been developed and applied.

用于惰性气体雾化 (EIGA) 的电极感应熔化的数值建模和优化

电极感应熔化惰性气体雾化 (EIGA) 是为增材制造需求生产高质量球形粉末的最先进工艺。对 EIGA 粉末不断增长的需求推动了对小型 Ø50 mm Ti-6Al-4V 电极的成熟雾化以及钽等新型耐火材料的雾化的兴趣。然而，在使用 Ø150 mm Ti-6Al-4V 和 Ø50 mm 钽电极的首次测试中，观察到了熔化稳定性方面的困难。为了克服这些困难并提高对感应耦合细节和有利熔化条件的理解，开发并应用了电极感应熔化的数值模型。
