Vacuum air atomization (VIGA)

Vacuum cleaner air atomization describes the smelting of steel or metal alloys under vacuum cleaner conditions. Under gas security conditions, the steel fluid flows out (descending) with the protected crucible and diversion nozzle. It is atomized and gotten into items by the high-pressure air movement through the nozzle. A a great deal of little beads solidify into spherical or almost spherical particles during flight to achieve the objective of powder-making.

Electrode Induction Gas Atomization (EIGA)

The electrode induction gas atomization powder-making process is to accomplish local refining of built alloy poles under ideal vacuum problems and protective gas problems. The metal liquid continuously moves downward vertically through the nozzle, and the high-pressure airflow atomizes the metal liquid via the nozzle. It breaks into a lot of small droplets, and the beads solidify into particles during flight.

Plasma rotating electrode (PREPARATION)

Plasma revolving electrode powdering modern technology is currently among the vital modern technologies for generating top quality round metal powders. The centrifugal force created by the high-speed rotation of the electrodes tosses out the liquid movie to create beads, which are atomized and strengthened into round powders in an inert environment.

Plasma wire atomization ()

Plasma wire atomization uses high-purity steel or alloy cord as basic material, which is sent to a high-temperature area with plasma as the warmth resource through a wire straightener for melting. At the exact same time, the molten liquid is atomized by the gas to form little droplets. Then, It spheroidizes under the action of surface area tension and cools down and solidifies right into powder during the dropping process.

Plasma Spheroidization (PS)

Plasma spheroidization uses DC arc or radio frequency plasma as the heat resource to heat the gas. The raw material powder is sent into the high-temperature plasma location via the service provider gas powder feeding tool to take in heat and melt. Under the action of surface stress, spherical droplets are created, and after that the liquid An innovation in which declines are cooled and strengthened right into powder through a significant temperature slope.

Water atomization

The basic concept of water atomization is that after the raw steel materials are thawed in the heating system, the thaw is put into a tundish placed at the top of the atomization chamber. The melt circulations through the opening at the end of the tundish right into the atomizer and is broken down into components by the high-pressure water jet. The molten beads cool and strengthen throughout dropping and deposition to develop a powder, and lastly, the water-powder blend is dried out, dried out, and accumulated.

    Ultra-fine grinding of silica can be achieved by silica wet grinder mg silicate

    Silica is a not natural compound and among the most important compounds of silicon. It exists in nature in crystalline kinds (such as quartz, cristobalite, chalcedony, agate, opal, and so on) and non-crystalline particle, uneven or bumpy kinds. Silica is insoluble in water and does not respond with water, however it can respond with alkali […]
