introduction of reduced iron powder

Grey or black powder, also called "double agent", capable of absorbing moisture and oxygen in the air, often used in food preservation.Reduced iron powder by ferroferric oxide commonly under the condition of high temperature on hydrogen flow or carbon monoxide reduction in gas generated, main ingredients for the loose structure of elemental iron.Because of reduced iron powder for powder itself, coupled with its microstructure is very loose, so its surface area is great.In the chemical production and laboratory operations often used as a reductant.
Reduced iron powder is the use of solid or gaseous reductant (coke, charcoal, anthracite, water gas and conversion of natural gas, decomposition of ammonia, hydrogen, etc.) of reduced iron oxide (iron concentrate, rolled steel scale, etc.) for producing sponge iron.Reduction process is divided into carbon reduction (solid) reduction and secondary reduction at a time, a reduction is solid carbon reduction for making sponge iron, a reduction is the main process: (iron concentrate, the rolling steel scale, etc.) - drying - magnetic separation to crushing, screening and canning to enter a reduction furnace, sponge iron.Secondary fine reduction process: sponge iron to flush, the broken - magnetic separation - the second reduction furnace - powder block - solution broken - magnetic separation to sieving, grading to mixing, packaging and finished products.In the production of high quality iron powder by reduction method, the various parameters, Fe 98 or higher, 0.01 or less of carbon, phosphorus and sulfur is less than 0.03, the hydrogen loss of 0.1 0.2.

 Reduced iron powder use  

1, as the raw material of powder metallurgy products, iron powder consumption accounted for about 60 80 of total consumption;
2, as the electrode materials, add 10-70 in coated iron powder can improve the electrode welding process and significantly improve the deposition efficiency;
3, as the flame cutting of injection agent, when cutting steel products, to the oxygen - acetylene flame spray iron powder, can improve the cutting performance, expand the scope of cutting steel, improve the cutting thickness;
4, also can be used as a reducing agent in organic chemical synthesis, duplicator ink vehicle, etc.
 Reduced iron powder packaging and storage Packed in white woven bag, net weight 25 kg, can also according to customer requirements packaging.
precautions 1, transport and loading and unloading: iron powder in the process of transportation, shall not use iron hook towing, should prevent and hard material mixture, not a strong vibration, friction, hit, hit, it is strictly prohibited to throw, should be light light discharge, in order to reduce packaging, affect the use.
2, storage: should be stored in a cool and dry place, prevent both inside and outside packing bag is broken, and prevent be affected with damp be affected with damp and other substances, deposit effect use effect and to stay away from pollution sources.
3, it is strictly prohibited under water: iron powder to iron material, so in the process of transportation, storage and use, will absolutely prevent water immersion, due to flooding, easy to rust, seriously affect the use effect.
