SLPA-N

Industrial Plasma Rotating Electrode Process System

Suitable for mass production of fine metal powders (15-53um) such as Ni-based superalloy and high-strength steel

SLPA-N
Functional advantages
  • Combining advantages of high speed and mass production to realize diameter 50mm of electrode can be produced continuously and stably at 30000rpm without damaging the vacuum.

  • The overall design of equipment is compact, with low height, small footprint and simple installation conditions.

  • High energy density and melting temperature greater than 2600℃, capable of preparing various types of metal powders such as superalloy and refractory alloy.

  • High sphericity, almost no hollow powder or satellite powder.

  • Non-contact powder production in full process, high powder purity and oxygen increment is less than 100ppm.

  • Suitable for mass production of fine powder (15-53um) of metal powders such as Nickel base superalloy and high-strength steel.
