low carbon low titanium ferro phosphorus

In the presence of iron in the electric furnace, reducing phosphorus pentoxide in apatite with coke will obtain both phosphorus and ferro phosphorus. In order to make the smelting process run smoothly, in addition to apatite, coke and steel shavings, a proper amount of silica needs to be added to the charge composition. The requirements for these raw materials are as follows: apatite should contain P2O5 greater than 25%, CaO less than 50%, and the particle size of 5-40mm should for more than 80%; coke: fixed carbon is greater than 78%, particle size is 2-5mm; steel shavings: no non-ferrous metal inclusions, the length is less than 100mm;silica: containing SiO2 greater than 96%, particle size 5-40mm; all the input charge should be dry and the moisture should be less than 2%.

Ferro phosphorus as an additive for phosphorus element in steel making and casting. When using the steel sheet which contain phosphorus can prevent sticking between steel sheets.Adding appropriate amount of phosphorus during rolling production can improve its fluidity and avoid surface cracks. When producing high phosphorus wear-resistant cast iron, phosphorus forms a uniform binary eutectic structure in the casting. Due to the high hardness of the phosphorus eutectic, the appropriate amount of phosphorus is added to the brake shoe of the truck to improve its wear resistance. The phosphorus used in casting can improve the fluidity of cast iron, thereby improving the quality of castings, at present, ferro phosphorus is mostly used in the foundry industry.

Ferro phosphorus is a by-product of the production of yellow phosphorus. In recent years, the export volume has soared. With the increase in export volume, the requirements of foreign companies for the quality of ferro phosphorus have also continued to increase, now there are so much more requirements for the low titanium ferro phosphorus which require the content of titanium less than 2% or even less than 1%, generally the content of titanium in ferro phosphorus ranges from 0.3% to 2%.

Though sometimes the phosphorus treat as the bad elements, but for some special steel or castings, proper content of phosphorus can improve wear-resistance, Anyang Huauto Metallurgy Co.,Ltd can supply the low carbon and low titanium ferro phosphorus, if any need welcome for contact.
