The anode metal rod melts under the action of the plasma hot arc, and the molten metadroplets diverge into

small droplets along the tangential direction under the action ofcentrifugal force, and finally solidify and spheroidize into powder.

The raw metal wire is melted and atomized into fine metal droplets by the high-temperature and high-speed hot plasma jet generated by one or more plasma torches → and finally solidified and cooled into fine metal powder.

The metal material is melted in the heating furnace and then added into the holding furnace. It is atomized into spherical powder under the action of high-pressure protective airflow through the high-pressure guide nozzle below.

The metal rod is melted into liquid by the smelting coil, then atomized into fine particles by the high-pressure nozzle, and quickly cooled into spherical shape. Finally, it is collected by the powder collecting device.

The RF induction plasma spheroidization process has a high temperature (the center temperature can reach 10,000°C), which shows great advantages for the spheroidization of high-melting-point refractory metals. At present, it is the most feasible technical route for large-scale production of refractory alloy spherical powders. During the powder spheroidization process, the equipment has a high spheroidization rate, good sphericity, no elliptical and planetary ball phenomena, and low surface roughness.

The surface vibrates with ultrasonic frequency and wets the metal solution on the surface. The molten liquid spreads into a liquid film under the action of ultrasonic vibration. When the amplitude of the vibration surface reaches a certain value, it is broken under the action of ultrasonic vibration, and the aroused droplets fly out from the vibration surface to form droplets. This phenomenon is used in air humidifiers to effectively generate water mist and spread in the air; similarly: the metal solution soaks the vibration surface of the acoustic vibration tube component to form a standing wave, and the molten metal droplets are sprayed to the surroundings. When these droplets solidify, they will become spherical powder particles.
