1. Purpose of the Equipment
1.1 Utilizing crucible-based vacuum induction melting combined with inert-gas atomization to produce microcrystalline or amorphous spherical powders of metals and metal alloys. This process is ideal for the R&D and preparation of powder materials such as high-temperature alloys, special steels, copper alloys, aluminum alloys, and more.
1.2 Special alloy powders are prepared using crucible-free electrode induction melting combined with inert gas atomization; this method is ideal for the research and development of ultra-pure metal powders, including reactive metal alloys and high-temperature refractory metal alloys.
2. Technical Features
2.1 Combining EIGA and VIGA functionalities, it caters to the preparation of various types of powders and is particularly well-suited for research and development.
2.2 Utilizing patented technology, the device allows for easy and convenient operation—simply by replacing the coil and atomizer, no furnace replacement is required to switch functions.
2.3 Autonomous setting of the atomization process to meet the preparation requirements for powders of various specifications;
2.4 Effective dust-proof and explosion-proof measures—safe and reliable;
2.5 Precision manufacturing, compact structure, and aesthetically pleasing layout.
