Vacuum air atomization (VIGA)
Vacuum air atomization describes the smelting of steel or steel alloys under vacuum cleaner problems. Under gas defense problems, the steel liquid drains (downward) through the shielded crucible and diversion nozzle. It is atomized and burglarized items by the high-pressure air movement via the nozzle. A large number of small droplets solidify right into round or almost spherical bits during 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 built alloy poles under appropriate vacuum conditions and protective gas problems. The steel fluid continuously streams downward vertically through the nozzle, and the high-pressure air flow atomizes the steel fluid through the nozzle. It burglarizes a large number of small beads, and the droplets strengthen right into particles during trip.
Plasma rotating electrode (PREP)
Plasma turning electrode powdering innovation is presently one of the important innovations for producing high-grade spherical metal powders. The centrifugal force created by the high-speed rotation of the electrodes throws away the liquid movie to create droplets, which are atomized and solidified right into round powders in an inert ambience.
Plasma cord atomization (PA)
Plasma wire atomization utilizes high-purity steel or alloy cord as resources, which is sent to a high-temperature location with plasma as the warmth resource with a wire straightener for melting. At the same time, the molten fluid is atomized by the gas to develop small droplets. Then, It spheroidizes under the action of surface tension and cools and strengthens into powder throughout the falling process.

Plasma Spheroidization (PS)
Plasma spheroidization utilizes DC arc or superhigh frequency plasma as the heat resource to warm the gas. The raw product powder is sent into the high-temperature plasma location through the provider gas powder feeding tool to soak up warm and melt. Under the activity of surface area stress, round beads are created, and after that the liquid A technology in which drops are cooled and strengthened into powder with a substantial temperature gradient.
Water atomization
The standard principle of water atomization is that after the raw steel materials are thawed in the heater, the melt is poured right into a tundish put at the top of the atomization chamber. The thaw flows through the opening at the bottom of the tundish right into the atomizer and is broken down into parts by the high-pressure water jet. The molten droplets cool and solidify during dropping and deposition to form a powder, and lastly, the water-powder combination is dehydrated, dried, and collected.
