Introduction of Ferro Phosphorus

Ferro phosphorus is obtained from electric furnace for phosphorus making, which is a symbiotic compounds with a phosphorus content range of 20-26% and silicon content range of 0.1-6%. The ferro phosphorus can change the corrosion resistance and chip resistance of steel. In addition, ferro phosphorus is usually used as an alloy agent to produce phosphate in the steel making industry. Ferro phosphorus is a combination of phosphorus with iron and is widely applied in high-strength low alloy steel as ingredient and a good dehydrating agent that can remove water during the alloy formation.

Usage of Ferro Phosphorus

Ferro phosphorus is a harmful impurity for many steels. But some cases it has its special roles in the steel making industry for instance ferro phosphorus is added to certain steel grades to improve the strength, corrosion resistance and workability of steel as well as the brittleness of steel. Ferro phosphorus can improve the fluidity of molten iron in the cast iron as well as improve casting performance and surface quality; gray cast iron contains 05% ferro phosphorus which can increase the tensile strength; wear-resistant cast iron contains about 0.15% ferro phosphorus which can significantly improve its wear resistance. For example, the train brake shoe contains 0.7%-1.0% phosphorus, forming a uniform binary phosphorus eutectic structure in the casting and distributed in a network. Phosphorus with high eutectic hardness improves not only its wear resistance but also thermal and thermal properties. Moreover, it can make uniform wear surface and less sparking when rubbing. Besides, containing phosphorus 20% phosphorus iron is ground into ultrafine powder, which can be used as a coating instead of ultrafine Zinc powder. For instance, widely used in rolling ,automobile cylinder sleeve ,engine roller and large foundry parts to increase Corrosion resistance and wear resistance of the mechanical parts.

Production of Ferro Phosphorus

Ferro Phosphorus is a by-product of the steel manufacturing process, as when pig iron is being converted, the conversion process will skim Ferro Phosphorus from the top of the slag. This was first done using the basic Bessemer process or the Thomas process. Anyang Huatuo Metallurgy Co.,LTD, as professional ferro phosphorus manufacturer, was over 20 years' experience in production various ferro alloy. We have professional facilities and complete production line for metallurgical material. If you have any question about ferro alloy purchase, you can send us email or telephone us.
