Product Description

Metal Powder Atomizing Equipment

VIGA Gas Atomization Equipment

 

Vacuum melting inert gas atomization 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.

The equipment is composed of vacuum smelting system, atomization system, gas supply system, powder collecting system, cooling water system, system integrated control system,atomizing tower support, steel structure platform and so on.

System for selection:
1.Atomizing gas heating device
2.CCD video surveillance system (to observe equipment operation status in time)
3.On-line laser particle size monitoring system
4.Online oxygen content monitoring system
5.Pressure difference controlling system
6.Fluid limiting diversion tube heating system
7.Pneumatic powder classification system
8.Multistage high vacuum melting system (max. vacuum degree: 6.7x10-3Pa)
9.Melting and Atomizing temperatures monitoring system

Vacuum induction melting and inert gas atomization is the leading process for production of a variety of high-performance metal powders and essential for quality manufacturing of Ni-based super-alloys as well as Fe-, Co-, Cr-based and other special alloy powders. In the VIGA system, a vacuum induction melting unit is integrated with an inert gas atomization unit. The starting materials are melted using electromagnetic induction which couples electrical power into the crucible/material under vacuum or in an inert gas atmosphere. Once the desired melt homogeneity and chemical composition have been achieved, the material is poured into a tundish by crucible tilting. The fine metal stream flowing from the tundish orifice into the atomization nozzle system is subject to a high-pressure, inert-gas jet and then atomized. The combination of molten metal and gas jet creates a spray of micro-droplets that solidifies in the atomization tower and forms fine powder with spherical shape.
