What Is Iron Powder Lead Generation Approach?
Iron powder is powdered iron ore, in theory, all containing iron or iron compounds can be called iron ore, but industrially or commercially, and iron ore is not only to contain the ingredients of iron and must have a value line.
Since its started in the early 1930 of the 20th century iron powder for powder metallurgy industry, spawning a number of iron powder production methods. Due to technology and economic Shang of various reason, which many method never beyond experiment or in the try stage, for example with hot hydrogen restore chloride Asia iron of chemical metallurgical method; another some method, such as Vortex spin mechanical crushed method, and water solution electrolytic method, and flow of bed hydrogen restore method, and rotating disc atomization liquid steel method, and air atomization liquid pig iron method and the into gas and solid carbon of joint restore method,, experience has relative short time of industrial application, then for appeared other more has competitive of method and no longer for iron powder of industrial production. Carbonyl iron powder production by (see Carbonyl milling method), because of its grain is fine, expensive, does not apply for sintered machine parts and electrodes, but its structure special high purity, and shows excellent performance. Nowadays dominating iron powder market, production of iron powder is: hegenasi belonging to iron oxide reduction process method and the long, low carbon molten steel by spray method, is a high-purity pig iron blast mill and decarbonization method of QMP and r); hegenasi method and amount of water atomized iron powder production by a landslide.
Rotary vibrating sieve can be used for coarse-level screening, but for high-precision grade you can use air classifier, for oxygen-sensitive explosive, you can only use the JZDF nitrogen iron powder grading grading machines for high-precision classification.
