Pink is not out of the refining, iron production process there are several:
One is the mechanical crushing method, the use of iron scrap crushing device for crushing and processing, and then sieved to obtain the desired particle size of the iron powder;
One is the use of water or gas atomization way, a reduction of the use of molten iron is crushed to the required particle size high-pressure water or high pressure gas will be required, and then the second reduction, the proceeds of atomized iron powder; well as chemical decomposition , can produce a variety of uses iron electrolysis, evaporation condensation method, etc., are a different process is mainly designed for different purposes for processing.
One is the reduction method, the use of iron oxide or ultra-fine powder as raw material, and then a series of processing, after two consecutive reduction, crushing, screening, co-awarded the iron powder, colloquially known as reduced iron;
