FAQ of VIGA equipment
What is VIGA equipment?
VIGA equipment is a specialized system used for the production of alloy metal powders through a process that involves vacuum induction melting of the metal followed by inert gas atomization to form fine powder particles.
How does VIGA equipment work?
VIGA equipment works by melting the desired metal in a vacuum chamber using induction heating. Once the metal reaches a molten state, inert gas is introduced to atomize the molten metal into fine droplets, which rapidly solidify into powder particles as they cool.
What materials can be processed with VIGA equipment?
VIGA equipment is versatile and can process a wide range of materials, including various alloy compositions and metals such as stainless steel, die steel, superalloys, cobalt-chromium alloys, and aluminum alloys.
What are the advantages of using VIGA equipment?
Some advantages of VIGA equipment include efficient pulverization, precise control over particle size distribution, high cooling rates leading to fine microcrystalline structures, low gas content in the powder, and the ability to achieve continuous production with customizable settings.
Is VIGA equipment suitable for mass production?
Yes, VIGA equipment is designed for continuous mass production of alloy metal powders. Its efficiency, throughput, and minimal downtime make it well-suited for industrial-scale production.
