Ferro Phosphorus Application

The ferro phosphorus is made from the Phosphorus furnace system. It is a symbiotic compound containing 20-26% phosphorus and 0.1-6% silicon, which can change the corrosion resistance and chipping properties of steel. Ferro phosphate is used as an alloying agent in the steelmaking industry and can also produce phosphate. There are two varieties of FeP1 and FeP2 produced in China, containing 15-20% phosphorus.
 

Phosphorus is a harmful impurity for most steels. But in some cases it still has its special effect. For example, adding phosphorus to certain type of steel can improve the strength, corrosion resistance and machinability of steel, but it also influence the brittleness of the steel. Adding phosphorus to cast iron can improve the fluidity of the molten iron, thereby improving the performance and surface quality of the casting; gray cast iron contains 0.5% phosphorus, which can increase its tensile strength. Wear-resistant cast iron contains about 0.15% of phosphorus, which can significantly improve its wear resistance.
 

Ferro Phosphorus is gained as a by-product of steel manufacturing, the result of the conversion of pig iron, removing it from the side in contact with the slag produced during this process. It can also be obtained as a by-product in the production of phosphorus.


 

The Application of Ferro Phosphorus include:

The manufacturing of phosphorous castings

The manufacturing of high-strength special steels low-Alloy

Its ability to be used as a deoxidizing agent in steel
