NHL VIGA Series Vacuum Induction Gas Atomizer
It enables the production of micron-sized spherical metal powder particles through rapid cooling at rates between 105-106 K/S！
The NHL VIGA Series atomization system utilizes closely coupled fine atomization technology developed by Navector Laboratory, with independent intellectual property rights. It enables the production of micron-sized spherical metal powder particles through rapid cooling at rates between 105-106 K/S.
Working Principle
The metal is first melted in a heating furnace and then transferred to a holding furnace. It is atomized into spherical powder by high-pressure protective airflow, which passes through a specialized guide nozzle to ensure fine atomization. The cooling process forms uniform, spherical metal powders.
This system is specifically designed for batch production ranging from 1 to 500 kg of micron-sized spherical powders, including stainless steel, copper alloys, aluminum-based alloys, and high-temperature alloys. The produced powder features low oxygen content, uniform particle distribution, and fine granularity. It is highly spherical, and the production process ensures safety, environmental protection, and energy efficiency.
The system features a modular design, allowing for the addition of various optional modules, including high temperature and high pressure configurations, to accommodate the research & development and production of a wide range of alloy powders across different scales.
Advantages
Low Gas Consumption: Efficient use of atomizing gases to reduce operational costs.
Low Hollow Rate: The produced powders have minimal hollow structures, ensuring high density and performance.
High Sphericity of Powder Particles: The process ensures powders with excellent spherical shapes, ideal for various applications.
High Fine Powder Yield: The system can efficiently produce a high yield of fine powders.
High Purity of Final Product: The powder produced has minimal contamination and high purity, meeting stringent quality standards.
The system can provide different atomization gas supply options depending on the specific atomization process requirements, including:
- Argon
- Helium
- Nitrogen
For different alloy requirements, the system is capable of providing a 1-5 kg alloy melting and atomization capacity (using steel as an example). Additionally, all process data during production is recorded for comprehensive tracking.
The system offers a variety of customizable modules to meet specific needs, including:
- Water and oxygen monitoring
- Infrared temperature measurement
- Vacuum pump upgrades
- Smelting intermediate feeding
- Gas preheating
- Quick cooling with return air
- Additional tundish units
