Metal powder preparation process inventory-atomization method 304 stainless steel

Vacuum air atomization (VIGA)&

Vacuum cleaner air atomization refers to the smelting of steel or steel alloys under vacuum cleaner problems. Under gas protection problems, the steel fluid drains (down) through the insulated crucible and diversion nozzle. It is atomized and gotten into pieces by the high-pressure air movement via the nozzle. A multitude of small beads solidify into round or nearly spherical fragments throughout flight to achieve the function of powder-making.

Electrode Induction Gas Atomization (EIGA)&

The electrode induction gas atomization powder-making procedure is to accomplish regional refining of upreared alloy rods under appropriate vacuum cleaner conditions and protective gas problems. The steel fluid constantly flows down up and down via the nozzle, and the high-pressure air flow atomizes the metal fluid via the nozzle. It gets into a multitude of tiny beads, and the droplets solidify right into bits throughout trip.

Plasma rotating electrode (PREPARATION)&

Plasma rotating electrode powdering innovation is presently among the crucial technologies for generating high-quality spherical steel powders. The centrifugal force created by the high-speed rotation of the electrodes throws out the fluid film to create beads, which are atomized and strengthened right into spherical powders in an inert atmosphere.

Plasma wire atomization ()&

Plasma cable atomization makes use of high-purity steel or alloy cord as resources, which is sent out to a high-temperature location with plasma as the warm source via a wire straightener for melting. At the exact same time, the liquified liquid is atomized by the gas to develop small droplets. After that, It spheroidizes under the action of surface area stress and cools and solidifies into powder during the dropping procedure.

Plasma Spheroidization (PS)&

Plasma spheroidization makes use of DC arc or radio frequency plasma as the warm resource to heat the gas. The raw product powder is sent out into the high-temperature plasma location with the service provider gas powder feeding tool to take in warm and thaw. Under the activity of surface area tension, round beads are developed, and then the fluid A technology in which decreases are cooled and strengthened into powder via a substantial temperature level gradient.

Water atomization

The standard principle of water atomization is that after the raw metal products are thawed in the heater, the thaw is put into a tundish positioned on top of the atomization chamber. The thaw circulations through the opening at the end of the tundish into the atomizer and is broken down right into parts by the high-pressure water jet. The molten beads cool down and solidify throughout falling and deposition to create a powder, and ultimately, the water-powder mixture is dehydrated, dried, and collected.
