Experiments of the dephosphorization of molten iron containing chromium (≤27 wt%), carbon (≤6 wt%), and phosphorus (0.1, 0.04 wt%) by the use of the flux of Na2O-SiO2-NaF system were carried out in the temperature range from 1 300°C to 1 600°C.
Effects of flux composition, carbon and chromium content in molten iron and temperature on the dephosphorization were made clear.
Relations between phosphorus and chromium distribution ratios obtained at the end of runs and carbon content in molten iron were also investigated. These distribution ratios depend on the carbon content strongly.
