Plasma Rotating Electrode Process

Plasma Rotating Electrode Process for Atomization of Spherical Metal Powders

Target: Research, experiment, development and production of high-quality spherical metal powder in universities and research institutes (especially suitable for new material development)

The main advantages of the equipment:

1. The working speed is greatly increased, and the yield of fine powder is higher;

2. The sphericity of the powder reaches more than 95%;

3. The working environment is carried out under two inert atmospheres of Ar or He, especially suitable for the development of alloy powders such as Ti, Ni, Co, stainless steel, and refractory metals;

4. The whole process of milling is non-contact milling, with high powder purity and low impurity content;

5. The floor area is only 4m×3m, and the installation conditions are simple;

6. Simple and professional operation interface design;

7. The process technology and personnel training system are perfect;

 

Basic principle: The consumable electrode is made of metal or alloy, whose end is heated by plasma arc and melted into liquid. The centrifugal force of the high-speed rotation of the electrode throws the liquid and pulverizes it into fine droplets. The effect of surface tension during the condensation process, and eventually, the spherical powder is made.

 

Process features: The powder produced has a narrow particle size range, smooth and clean powder particle surface, less hollow powder and satellites, less gas inclusions, and high powder quality, suitable for spraying, hot isostatic pressing and 3D printing processes.

 

Uses: Production of nickel-based superalloy powder, titanium alloy powder, stainless steel powder and refractory metal powder, etc.

 

Model: SLPA-D desktop-level plasma rotating electrode atomizing and powdering equipment for scientific research.

 

Features of the equipment: The working speed is greatly improved, the powder sphericity reaches more than 95%, and the fine powder yield is significantly improved; the working environment of pulverizing is carried out under two inert atmospheres of Ar or He, and the oxygen increase in the powdering of active metals such as titanium alloys. The amount is controlled within 100ppm, and the oxygen increment of metals such as superalloys can reach the level of 50ppm; the equipment is compact in design, covering an area of only 4m × 3m, which greatly reduces the requirements for installation conditions, and the concise and professional operation interface design allows users to operate more easily. For convenient use; users can develop new alloy powders according to their needs, especially suitable for universities, scientific research institutions and other units to conduct trial production of new material system powders and development and production of small batches and multiple varieties of high-quality spherical metal/alloy powders.

VIGA

Based on the advanced vacuum inert gas atomization (VIGA) and electrode induction gas atomization (EIGA) systems, high-quality metal powder products with low oxygen content, high sphericity and excellent flowability have been developed in AMC company.


VIGA
VIGA system comprises a Vacuum Induction Melting (VIM) furnace where the alloys are melted, refined and degassed. The refined melt is poured through a preheated tundish system into a gas nozzle where the melt stream is disintegrated by the kinetic energy of a high pressure inert gas stream. The metal powder produced solidifies in flight in the atomization tower located directly underneath the atomization nozzle. The metal powder is collected in cyclone separation system.

EIGA

Based on the advanced vacuum inert gas atomization(VIGA) and electrode induction gas atomization(EIGA) systems, high-quality metal powder products with low oxygen content, high sphericity and excellent flowability have been developed in AMC Company.
 
EIGA
EIGA system is an electrode induction melting and atomizing process for producing powder of high-reactivity alloy, as well as refractory alloy. In the process, prealloyed rods in form of an electrode are inductively melted and atomized without any melting crucible. The melting of the electrode is accomplished by lowering the slowly rotating metal electrode into an annular induction coil. The melt droplets from the electrode fall into the gas atomization nozzle system and are atomized with inert gas, solidify in flight in the atomization tower. The metal powder is collected in cyclone separation system.
