Plasma Rotate Electrode Atomization Powder Production Equipment

The plasma atomization powder production equipment is specialized for high temperature alloy powder in particle size ranged from 50 to 500μm. This powder metallurgy equipment adopts non transferred arc plasma heating system and high speed rotating atomizer for powder production, involving technologies from industries of machinery, electronic, pneumatic, hydraulic, high vacuum and plasma, etc.

However, the predominating technologies of this powder production equipment comprise main structure fabrication, vacuum sealing, vacuum pumping, high speed rotating and transmission device, as well as plasma heating and melting system, etc.

Metal or alloy are made into consumable electrodes as feedstock. Its end face is heated by plasma torch and melt into molten liquid, then the molten is ejected by the centrifugal force of high-speed rotating electrode, crushed into small droplets and solidified into powders. Helium is the best choice as protective atmosphere because its thermal conductivity is highest and alsmost 10 times of Ar. By using helium, cooling speed can be increased and plasma torch performance can be improved.

1.It used for producing high melting and alive metal powders, such as nickel-based or Ti-based alloy powder. It’s also suitable for producing various alloy powders, such as steel, cobalt, chromium, etc.
2.The feedstock doesn’t contact with refractory materials during melting and atomizing processes, which eliminates non-metallic inclusions of pollution sources and produces clean powders.
3.The atomized powders is of regular shape, high sphericity, bright surface and good fluidity.
4.There’s no satellite phenomenon and hollow powder.
5.Powder particle distribution.
6.Manufacturing numerous special alloy powders as fast solidification overcomes aliquation.
