Dereived iron powder is produced by reducing iron oxides (such as iron concentrate, mill scale, etc.) with solid or gaseous reducing agents (like coke, charcoal, anthracite, water gas, ammonia decomposition, hydrogen, etc.) to form a spongy iron. The iron powder produced by the reduction method has Fe≥98%, C≤0.03%, P and S both less than 0.03%, and hydrogen loss of 0.1～0.2%.

The primary uses of还原铁粉 include:

As raw materials for powder metallurgy products, the consumption accounts for about 60-80% of the total consumption of iron powder.

② As raw material for welding rods, adding 10-70% iron powder to the flux can improve the welding process of the welding rod and significantly enhance the deposition efficiency.

③ As a flame cutting jetting agent, by injecting iron powder into the oxygen-acetylene flame during steel cutting, it improves the cutting performance, expands the range of cuttable steel grades, and increases the cuttable thickness.

④ Can also be used as a reducing agent in organic chemical synthesis, as a carrier for copy machine inks, etc.

⑤ For diamond saw blade cores, enhancing diamond encapsulation strength while reducing manufacturing costs.

⑥ Aluminum alloy iron additive, steelmaking core wire, soft magnetic material iron powder core, etc.
