摘要：

With simulation of the composition of slag and liquid steel at tapping, the experiments of dephosphorization and rephosphorization by using CaO-SiO2-Fe2O3-MnO2-MgO-P2O5 fluxes were performed at 1853 K in the laboratory scale. The influence of basicity (CaO/SiO2) and oxidability (Fe2O3+MnO2) of the fluxes on dephosphorization and rephosphorization were investigated. The condition for preventing rephosphorization is that the values of basicity and oxidability should be larger than their critical values respectively. Using BaO instead of CaO in the fluxes can control the rephosphorization of liquid steel.
