Description

[0002] Iron powder mainly includes reduced iron powder and atomized iron powder. The iron powder production processes in the current iron powder market mainly include the following: the Högenas method, the Pyron method, and the low-carbon steel liquid water atomization method. When the low-carbon steel liquid water atomization method is used to produce iron powder, the low-carbon scrap steel is melted and slag-made to remove or reduce phosphorus, silicon and other impurity elements, and then flows into the atomizer through the nozzle. At the same time, a high-pressure (about 8.3MPa) water flow is sprayed in to break the metal flow into droplets. The droplets fall into the water tank below to cool and solidify into powder. After magnetic separation, dehydration and drying, the powder is sent to a belt furnace and reduced and annealed at 800-1000°C with decomposed ammonia to obtain high-purity water-atomized iron powder. Finally, the dry iron powder is batched and input into the storage bin for temporary storage;
