Ferro Phosphorus Function

At the electrothermal production of yellow phosphorus from a phosphorite, quartzite and coke mixture, 1 ton of the phosphorus produced gives to 300 kg of a by-product - ferrophosphorus is used for melting of alloyed phosphorus-containing steels, for example like the automatic steels, and Iron casting. 

Phosphorus in the steel industry is used as an alloying agent, iron alloy additives for us in the metallurgical and deoxidizer. In general steel products, phosphorus is harmful ingredients, but in some very special products, the addition of phosphorus, can also improve the performance of some certain aspects of the steel.

What’s more, the ferro phosphorus is widely used in roll, auto cylinder liner, engine roller and large castings in order to increase mechanical parts corrosion resistance and abrasion resistance.


Application:

1, Coating: As a partial substitute of zinc powder with 35% calculated as weight.

2, Welding Coating: the ferro phosphorus enables single layer or multi-layer coating with the weldability characteristic, applicable to the paiting of coating, adhesion, sealant, etc.

3, Conducting coating: Enable the coating with the electric-conducting and thermal conducting performances.

4, Shielding layer: It can be used as a partial replacement of nickel pigmen or copper pigment shielding layer against electromagnetic interference.

5, Powder metallurgy additive: capable of lowering sintering temperature and promoting press-forming efficiency and increase the wet strength of non-sintering dust. 

6, Electric welding: Applied in the manufacture of automotive and other machines.
