Vacuum air atomization (VIGA)
Vacuum air atomization describes the smelting of metal or steel alloys under vacuum cleaner problems. Under gas defense problems, the steel fluid spurts (downward) with the insulated crucible and diversion nozzle. It is atomized and gotten into pieces by the high-pressure air flow with the nozzle. A large number of small droplets strengthen into spherical or almost spherical fragments throughout flight to accomplish the purpose of powder-making.

Electrode Induction Gas Atomization (EIGA)
The electrode induction gas atomization powder-making procedure is to execute local refining of upreared alloy poles under ideal vacuum conditions and protective gas problems. The steel fluid constantly streams downward up and down with the nozzle, and the high-pressure air flow atomizes the metal fluid through the nozzle. It burglarizes a large number of tiny beads, and the beads solidify into bits during trip.
Plasma rotating electrode (PREP)
Plasma rotating electrode powdering innovation is currently among the essential modern technologies for producing top notch spherical metal powders. The centrifugal pressure produced by the high-speed turning of the electrodes tosses out the fluid film to develop droplets, which are atomized and solidified into spherical powders in an inert atmosphere.
Plasma cord atomization ()
Plasma cable atomization uses high-purity steel or alloy wire as basic material, which is sent to a high-temperature area with plasma as the warmth resource with a wire straightener for melting. At the same time, the liquified liquid is atomized by the gas to develop little beads. Then, It spheroidizes under the action of surface area stress and cools down and strengthens into powder during the falling procedure.

Plasma Spheroidization (PS)
Plasma spheroidization utilizes DC arc or radio frequency plasma as the warm source to heat up the gas. The raw material powder is sent right into the high-temperature plasma area via the carrier gas powder feeding tool to take in warm and thaw. Under the activity of surface area stress, round beads are formed, and then the liquid A modern technology in which drops are cooled down and solidified right into powder with a big temperature level gradient.
Water atomization
The basic concept of water atomization is that after the raw metal products are melted in the furnace, the melt is poured into a tundish put on top of the atomization chamber. The thaw flows through the opening at the bottom of the tundish into the atomizer and is broken down right into components by the high-pressure water jet. The molten droplets cool and solidify throughout falling and deposition to develop a powder, and ultimately, the water-powder mixture is dehydrated, dried out, and accumulated.
