Iron Powder FE100.29 Specifications

FE100.29 is a high purity water atomized iron powder with  irregularly shaped and high density particles.  The high compressibility of FE100.29 makes it a perfect choice for manufacturing pure iron or iron alloy parts with high tensile strength as well as high compressive strength. FE100.29 is mainly used in powder metallurgy for production of high strength machine parts. FE100.29 may be mixed with graphite, copper powder and other metal powders to provide specific properties to the final product. It is also mixed with some lubricant such as zinc stearate before compaction.

Manufacturing process of FE100.29 water atomized iron powder

Iron metal is melted down in an electric arc furnace. The melt is teemed, slag-free, through a bottom hole into a ladle  where it is refined . The ladle is then transferred to the atomizing station  and the liquid iron is again teemed, slag-free, through a bottom hole in the ladle into a specially designed tundish.

From the tundish, the liquid iron  flows in through the center of a ring-shaped nozzle, where it is hit by jets of highly pressurized water. At this stage the stream of liquid iron explodes into fine droplets.

Air, swept along by the water jet and water vapor arising in the atomizing process, causes superficial oxidation of the small metal droplets. The solidified droplets and the atomizing water are collected in a container, where they settle as a mud. This mud powder is then de-watered and dried. The dried powder is magnetically separated from slag particles, screened, homogenized, and eventually transported to the annealing and reduction unit where the particles are therefore soft annealed, and their surface oxides and residual carbon are reduced in a belt furnace.
