Application Of Ferro Phosphorus

Ferro phosphorus is a phosphorus-containing iron alloy obtained from a phosphorus-making electric furnace, and its phosphorus content is between 20% and 26%, and its silicon content is between 0.1% and 6%. Ferro phosphorus may also contain a small amount of other elements, such as manganese, titanium, sulfur, carbon, etc., but the specific content varies with varieties. Ferro phosphorus is a by-product of yellow phosphorus production, which can change the corrosion resistance and chip resistance of steel. In steel, phosphorus is partially dissolved in ferrite and partially forms brittle compounds, which may affect the plasticity and toughness of steel.

Ferro phosphorus is used as an alloying agent in the steelmaking industry to improve some properties of steel, such as strength, corrosion resistance and machinability. But phosphorus is a harmful impurity for most steels because it may increase the brittleness of steel. In the foundry industry, ferro phosphorus is widely used in rolls, automobile cylinder liners, engine rollers and large castings to increase the corrosion resistance and wear resistance of mechanical parts. In the casting process, ferro phosphorus can improve the strength and hardness of castings, and further improve their wear resistance and compression resistance.

Ferro phosphorus can also be used to make the shells of grenades, shells, etc. Because of its brittleness, a large number of shrapnel can be obtained after the explosion, which improves the killing efficiency. In electronic products and chemical reagents, ferro phosphorus is used as a material of electronic components and a dopant in semiconductor production. Ferro phosphorus is ground into ultrafine powder, which can replace ultrafine zinc powder as the coating.

To sum up, as an important industrial raw material, ferro phosphorus is widely used in steelmaking, casting, fertilizer manufacturing and other fields. At the same time, the characteristics of ferro phosphorus also determine its application in some special fields such as electronic products and chemical reagents.
