中文摘要:
      采用数值模拟和实验研究结合的方法研究了增材制造钛粉的新型制备工艺-钛丝高频感应熔化气雾化技术(Wire Induction heating Gas Atomization, WIGA)的钛丝感应熔化部分。数值模拟得到了钛丝感应熔化模型的最优参数:感应线圈的夹角为90°;电源输出频率为450kHz;线圈最优单匝直径为8mm。钛丝直径选定为4mm,形成长度15mm金属液流的临界送丝速度为45mm/s。在此条件下,金属液产生350±50℃过热度时电源的临界输出功率为34kW。建立氩气保护氛围的钛丝感应熔化实验装置,通过实验研究得到TC4钛丝形成长度15mm液流的临界送丝速度为50mm/s,实验值与模拟值误差为10.0%。在此条件下,熔化产生350±50℃过热度液流,电源的临界输出功率为38kW,实验值与模拟值误差为10.5%。实验结果与模拟结果相互证明,得到了钛丝熔化的工程应用依据。

英文摘要:
      This study developed a new preparation process for titanium powder for additive manufacturing- Wire Induction heating Gas Atomization (WIGA). The combination of numerical simulations and experimental investigations was used to investigate the high frequency induction melting of titanium wire. The numerical simulations obtained the optimal parameters of the titanium wire induction melting model. The angle α of the induction coil is 90°. The power output frequency f is 450 kHz. The diameter of the titanium wire was 4mm, and the minimum wire feed speed was 45 mm/s when forming a 15 mm length of metal flow. Under this condition, the critical output power is 34kW when the molten metal generates 350±50°C of superheat. An argon atmosphere protective titanium melting experimental device was established. Through experimental investigations, the minimum TC4 wire feed speed was 50 mm/s when forming a 15 mm length of metal flow,and the error between the experimental and the numerical simulation was 10.0%. Under this condition, the minimum output power of the power supply was 38kW when generating a molten metal with a superheat of 350±50°C, the experimental and numerical simulation errors were 10.5%. The experimental and numerical simulation results proved each other, and the engineering application basis of high frequency induction melting of titanium wire was obtained.
