Iron poeder / reduced iron powder Overview:
　　Reduced iron powder from the iron oxide is generally under high heat conditions to restore the flow of hydrogen or carbon monoxide is generated in the gas stream , the main component of loose structure of elemental iron. Since the reduced iron powder itself , and the microstructure is loose coupled , so the maximum surface area . In chemical production and laboratory operations commonly used for high- reducing agent.

Iron / reduced iron works:
　　Reduced iron is the use of solid or gaseous popular reductant ( coke , charcoal, anthracite, water, gas, natural gas conversion , decomposition of ammonia , hydrogen , etc. ) reduction of iron oxide ( iron ore, rolled steel scales , etc. ) from the system spongy iron. Reduction process is divided into ( solid carbon reduction ) a reduction and secondary reduction, a reduction of carbon reduction from the system is solid sponge iron , a reduction of the main processes are: ( iron ore, rolled steel scales , etc. ) → drying → magnetic crushing and screening → → → → canning into a reduction furnace → sponge . Secondary fine reduction process: sponge brush clearance → → → crushing → magnetic powder block secondary reduction furnace → → → Magnetic crushing and screening → → → mixing → Packaging → grading finished . Produced by reduction of iron of high quality , standard parameters , Fe ≥ 98%, C ≤ 0.01%, phosphorus and sulfur are less than 0.03% , the hydrogen loss was 0.1 to 0.2 %. The main purpose of the reduction of iron are: reduced iron powder metallurgy products , this sector consumes 60% to 80% reduction of total iron . Welding with reduced iron powder , 10 to 70% iron in the coating can be improved welding electrode and significantly improve the deposition efficiency . Chemical use reduction iron powder , mainly used in chemical catalysts, precious metal restore, adding alloy , copper , such as replacement . Cutting stainless steel iron , steel products during cutting to oxygen - acetylene flame spray iron , can improve cutting performance , expanding the scope of cutting steel to improve the thickness can be cut . Continuous improvement of the powder metallurgy industry and technology, is currently widely used in aircraft powder metallurgy parts , firearms , motorcycles, family cars , automotive , agricultural , mining , power tools , machine tools, transportation and other machinery industries.
