Vacuum air atomization (VIGA)
Vacuum air atomization describes the smelting of metal or steel alloys under vacuum problems. Under gas protection conditions, the steel fluid drains (descending) via the protected crucible and diversion nozzle. It is atomized and gotten into items by the high-pressure airflow through the nozzle. A a great deal of small droplets strengthen into spherical or almost round fragments throughout flight to accomplish the function of powder-making.

Electrode Induction Gas Atomization (EIGA)
The electrode induction gas atomization powder-making procedure is to carry out regional refining of erected alloy rods under appropriate vacuum problems and protective gas problems. The metal liquid continuously moves downward vertically via the nozzle, and the high-pressure air flow atomizes the steel fluid with the nozzle. It gets into a large number of small beads, and the beads solidify into particles throughout flight.
Plasma rotating electrode (PREPARATION)
Plasma turning electrode powdering innovation is currently among the vital technologies for producing top notch round metal powders. The centrifugal pressure produced by the high-speed rotation of the electrodes throws away the fluid movie to create droplets, which are atomized and strengthened right into round powders in an inert atmosphere.
Plasma wire atomization ()
Plasma wire atomization uses high-purity steel or alloy cord as raw material, which is sent out to a high-temperature area with plasma as the warmth resource through a cable straightener for melting. At the very same time, the liquified liquid is atomized by the gas to create tiny beads. Then, It spheroidizes under the activity of surface area stress and cools and strengthens into powder during the dropping process.

Plasma Spheroidization (PS)
Plasma spheroidization makes use of DC arc or radio frequency plasma as the warmth resource to heat up the gas. The raw product powder is sent out into the high-temperature plasma location with the service provider gas powder feeding device to absorb heat and melt. Under the activity of surface tension, spherical beads are created, and afterwards the liquid A technology in which declines are cooled and strengthened into powder via a big temperature level gradient.
Water atomization
The standard principle of water atomization is that after the raw metal products are thawed in the heating system, the melt is put into a tundish placed at the top of the atomization chamber. The thaw circulations via the opening at the end of the tundish into the atomizer and is decayed right into parts by the high-pressure water jet. The liquified droplets cool and strengthen throughout dropping and deposition to form a powder, and ultimately, the water-powder combination is dehydrated, dried, and gathered.
