Application of Atomization Towers in Metal and Alloy Smelting

Vacuum Gas Atomization: The Core Process

1. Melting Phase: Metals or alloys are melted in a crucible within a vacuum chamber to prevent oxidation.
2. Atomization Phase: Molten metal flows through a heated crucible and a flow guide nozzle. High-pressure gas jets from nozzles shatter the liquid stream into tiny droplets.
3. Solidification & Collection: These droplets rapidly solidify into spherical or sub-spherical particles during their descent. Subsequently, a screening process separates particles into various sizes, yielding the desired metal powder.

Production Capacity and Material Range

• Capacity: The system accommodates production batches ranging from 5 to 1000 kg, catering to both small-scale research and large-scale industrial needs.
• Materials: It can produce powders from diverse metals and alloys, including iron-based, cobalt-based, nickel-based, aluminum-based, copper-based materials, and stainless steels.
• Customization: The equipment’s design is fully customizable. Customers can provide technical drawings for tailored manufacturing, ensuring the system aligns with specific process requirements.

Key Features of the Vacuum Gas Atomization System

1. Enhanced Microstructure: Droplets solidify rapidly during descent, eliminating segregation—an uneven distribution of elements—and resulting in a homogeneous microstructure.
2. Advanced Melting Technology: Induction heating via ceramic or graphite crucibles ensures efficient melting. Refining and pure flow guide techniques further purify the alloy materials.
3. High-Precision Atomization: Supersonic close-coupled gas atomization nozzles enable the production of ultra-fine powders across multiple alloy types, meeting stringent industry standards.
4. Efficient Collection & Environment-Friendly Design: A two-stage cyclone grading collection system maximizes the yield of fine powders while minimizing dust emissions, promoting both productivity and environmental sustainability.
