1. Equipment Principle and Applications
In a high-vacuum environment, high-purity inert gas is introduced, and the pre-fabricated alloy rod is fed into the conical induction coil inside the furnace via an external lifting and rotating mechanism for inductive heating and melting. The molten droplets are then directly injected into a specially designed atomizer nozzle system, where they are atomized into fine powder using high-pressure inert gas. This complete equipment setup offers advantages such as zero crucible contamination of materials and excellent sphericity of the resulting powder. By combining electrode induction melting with inert-gas atomization technology, it is possible to produce ultra-pure metal powders.

3. Technical Features
3.1 Utilizing crucible-free suspension melting technology, the material melting process is free from contamination;
3.2 Lower system leakage rate of 1×10⁻⁸ PL/S, providing high-purity gas supply and effectively controlling oxygen ingress;
3.3 Maximum melting temperature of 2500℃, enabling the production of powders for materials with even higher melting points;
3.4 The melting rate is well-matched with the atomization process, effectively controlling the particle size distribution range.
3.5 The high-pressure inert gas atomization process ensures high sphericity and packing density of the powder;
3.6 Effective dust-proof and explosion-proof measures, ensuring safety and reliability;
3.7 Precision manufacturing, compact structure, and aesthetically pleasing layout.
