What are the advantages and disadvantages of the reduction method, the atomization method and the electrolytic production of iron powder?

What are the production methods of iron powder?

The commonly used methods of production of iron powder include gas reduction, carbon fixation reduction, atomization, pyrolysis of carbonyl, electrolysis, etc., what are their advantages and disadvantages?

1. Advantages and disadvantages of gas reduction method:

(1)Compared with the solid carbon reduction iron oxide, the temperature can be reduced by the same degree of reduction, and the reduction time is shorter.
(2) with hydrogen reduction of iron oxide, the increased pressure is good for reduction, equivalent to raise the temperature to increase the speed of reduction, or, when using high pressure reducing, reduction temperature can be greatly reduced.
The reduction temperature is low, the obtained iron powder will not bond into a lump.
(3)But hydrogen reduction is difficult, high cost and low efficiency.

2. Advantages and disadvantages of carbon sequestration:

The advantages are low cost and high efficiency.
The disadvantage is that carbon is prone to carburizing when reducing iron powder.

3. Water atomization method to produce iron powder technology advantages and disadvantages.

1) short process, high production efficiency, suitable for large-scale production;
2) we can use cheap raw materials (scrap steel) to produce high-value and high-quality powder with high purity, uniform structure and good process performance;
3) the particle size and particle size distribution of water atomized pure iron powder produced by water atomization method can be adjusted within a certain range.
4) water atomization method not only the production of pure iron powder compressibility value is high, and high chemical purity, and can be used in the production of high density, high strength, high dimensional accuracy and wear resistance, corrosion resistance, shape, complex powder metallurgical parts, than with the types of products with reduced powder production.
Deficiency of water atomized iron powder production:

A one-time investment in equipment;
It is not conducive to the production of low density iron powder.

4. The carbonyl object thermal dissociation method.

The advantage is that the carbonyl iron powder is the most pure of all kinds of iron powder in the chemical composition, the disadvantage is that the carbonyl powder is expensive, and the metal carbonyl compounds have different degrees of toxicity when they evaporate.

5. Electrolysis

The advantage is that the iron powder produced is more pure, the electrolysis can also control the powder particle size, can produce ultrafine powder.
Disadvantages: power consumption, high cost.
