This research was conducted to study the effect of lime based Flux with the composition of CaO-20%CaF2-8%FeO on simultaneous removal of phosphorus and Sulfur from hot metal. The effects of Na2O and oxygen blowing were also studied. The experiments were performed using an induction furnace and hot metal produced in Isfahan Steel Company in the temperature range 1350-1450 ºC...

Since 10 million tons of steelmaking slag, which contains a few percent phosphorus, are annually produced, the phosphorus amount in slag is equivalent to annual import volume rock Japan. Therefore, attracting attention as potential resources. Phosphorus-concentrated obtained by dephosphorization reaction between high hot metal and oxidizing at temperature phosphorous comparable that rock. Howev...
