The effect of sulfur and carbon content in reduced iron powder.


Sulfur is harmful elements of iron powder, it makes the combination of iron and carbon, iron hard brittle, and synthesis of low melting point of iron sulfide and iron, using this kind of iron powder pressed powder metallurgy parts produced heat brittle and reduce the liquidity of iron liquid, so high sulfur iron powder is not suitable for powder metallurgy and iron powder used as electrode.
The content of sulfur in the national standard of the second reduced iron powder should not exceed 0.02%, so it is of great significance to adjust the secondary reduction process parameters to reduce the carbon and sulfur content in the finished iron powder.
The reduction parameters mainly include material thickness, reduction temperature and reduction time.
