Estimation of phosphorus distribution ratio at the end of blowing in BOF
Metallurgical and Materials Engineering, 2021 In integrated steel plants, the removal of phosphorous normally takes place during the primary basic oxygen furnace (BOF) steelmaking process. Phosphorous is usually introduced to the integrated steelmaking process through blast furnace additions, such as iron ore, coke, sinter, and fluxes.
