感应等离子球化钽粉制造研究

研究对比了两套不同功率的Tekna感应等离子球化设备进行钽粉球化制造的情况。重点分析了送粉速率对钽粉球化效果及生产效率的影响。结果表明，钽粉送粉速率的选择与设备使用功率、粉末原料流动性等多因素相关。在保障钽粉球化效果前提下，80 kW设备对钽粉处理效率远高于15 kW。大功率设备不仅在粉末处理速度上占据优势，而且粉末球化效果及成品率也相应提升。本文还论述了钽粉球化过程中出现的气化损耗、杂质去除等机理。

Study on the process of sphero tantalum powders by inductive plasma process

In this paper, two Tekna inductive plasma sphero systems with different powers were used to manufacture sphero tantalum powders. The influence of powder feeding rate on the powder sphero effect and manufacture efficiency was particularly analyzed. The results indicate that the selection of the powder feeding rate was related to factors both equipment power and powder flowability. On the condition of achieving good sphericity of tantalum powders, the manufacturing efficiency of 80 kW equipment was several times than that of 15 kW. The high-power equipment showed advantages not only on manufacture rate, but also on the sphero effect and manufacture yield. The elemental gasification and impurity cleaning mechanism in the sphero process were also discussed in this study.
