Vacuum Melting Inert Gas Atomization (VIGA) Equipment

Vacuum Melting Inert Gas Atomization (VIGA) Powder Manufacturing Equipment

Overview

Vacuum melting inert gas atomization powder manufacturing equipment is designed for producing metallic spherical powder by atomizing under certain conditions.

Working principle: Metal or alloy materials are melted under inert gas protection or vacuum condition, and the molten metal is poured through insulation tundish system into a gas nozzle where the melt stream is disintegrated into droplets by high pressure inert gas stream. The small droplets will be solidified into tiny spherical powders in flight in the atomization tower.

Optional functions:

• Atomizing gas heating device
• CCD video surveillance system (to observe equipment operation status in time)
• On-line laser particle size monitoring system
• Online oxygen content monitoring system
• Atomization pressure difference controlling system
• Fluid limiting diversion tube heating system
• Automatic pneumatic powder classification system
• Multistage high vacuum melting system (max. vacuum degree: 6.7x10^-3Pa)
• Melting and atomizing temperatures monitoring system

Features:

Combined with high vacuum technology, high temperature melting technology and high pressure gas atomization technology, vacuum melting inert gas atomization powder manufacturing equipment is especially suitable for the production of high quality powders and active metals/alloys. The produced powders have the characteristics of high purity, low oxygen content, high yield of fine powders, good appearance, etc..
