Ferrophosphorus solid

At present, ferrophosphorus mainly comes from the yellow phosphorus industry and is a by-product of yellow phosphorus produced by the electric furnace method. Since each ton of yellow phosphorus can only produce about 200 kilograms of iron phosphorus, its output is very small and cannot meet the needs of the continuously developing metallurgical and chemical industries.

In recent years, some people have used iron ore and phosphate ore as raw materials to produce iron phosphate through coke reduction and melting in a blast furnace using a spherical hot blast furnace (hot blast temperature 700-800°C). However, due to the corrosion of silicon tetrafluoride gas during the production process of this method, and the phosphorus vapor and generated iron phosphate can easily block pipelines and equipment, the production equipment does not operate smoothly; the phosphorus content in the iron-phosphorus products produced is less than 23%, Low output and high energy consumption.

In 1669, G. Brand discovered phosphorus. In 1826, P. Berthier produced iron phosphorus. In 1868, C. Brison patented the production of phosphorus and phosphoric acid in a blast furnace. In 1929, the blast furnace for producing hot phosphoric acid in Victor, USA, was put into operation. In the 1870s, patents appeared for the use of electric furnaces to smelt phosphorus and phosphorus iron. In 1925, the first 3000kW three-phase electric furnace was built in Bitfield for the production of phosphorus. In the future, electric furnaces will become the main equipment for phosphorus production. Ferrophosphate is a by-product of yellow phosphorus production.
