Electrothermal co-production of ferrosilicon, calcium carbide and gaseous phosphorus from the chilisay phosphorite
The article presents the results of studies on the use of the high-silicon phosphorites (51,8 % of Ca<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>, 25,6 % of SiO<sub>2</sub>) for the co-production of ferrosilicon, calcium carbide and gaseous phosphorus. The...

| description | The article presents the results of studies on the use of the high-silicon phosphorites (51,8 % of Ca<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>, 25,6 % of SiO<sub>2</sub>) for the co-production of ferrosilicon, calcium carbide and gaseous phosphorus. The studies included the electric smelting a charge in an arc furnace and using the second-order rotatable designs. The conditions of producing FeSi45 ferrosilicon (51,2-54,2 % of coke, 12,5-18,4 % of steel shavings) and FeSi25 ferrosilicon (53-58 % of coke, 39,7- 40 % of steel shavings) with extraction of 65-67,8 % of silicon into the alloy were determined. The second product of the process is technical calcium carbide with a capacity of 129-167 l/kg, in which from 44,8 to 64,1 % of calcium is extracted. At least 99,3 % of phosphorus during the electric smelting is sublimated. |
