Supply high content iron powder for metal reduction of metal processing factory

 

 

 

 

The -100 mesh iron oxide solid powder is sent to the gas converter reduction device, and the iron oxide solid powder and the reducing medium hydrogen or carbon monoxide are reversely moved and contacted in the gas converter reduction device, and the temperature in the gas reduction device is controlled at 500 to 800 ° C, The pressure of 1 to 10 kPa and the flow rate of the reducing medium are 2 to 5 times of the flow rate required for theoretical removal of oxygen in the iron oxide, and the reduction time is 1 to 3 hours. After the reduction, a dendritic ultrafine iron powder having a particle diameter of 1 to 30 μm is obtained. The ultrafine iron powder produced by the method has a length of 1 to 30 μm, has a good dendritic morphology, uniform particle size, large specific surface area, low production cost, and can be widely used for adsorbing materials, catalyst materials, and iron-based sintering molding. material.

 

 

 

 

1.Ultra-fine iron powder itself is non-toxic and harmless to the environment. Excessive inhalation can cause acute and chronic respiratory diseases. Pay attention to dust when using.
2. The ultrafine iron powder has fine particles, high surface activity, easy oxidation and combustion, and mainly prevents high temperature, leakage and contact with a large area of air, resulting in oxidative combustion during packaging, transportation, storage and use.
3. Ultra-fine particle size, low pine ratio, high purity, spherical, low carbon, good pressability, magnetic properties, good inductance and low loss. The ultrafine iron powder has an average particle size of less than 2 microns.
