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.
