A new process for the hot metal dephosphorization is examined. It is done in the 200 t hot metal ladle, soda ash being top charged, oxygen gas being top blown and nitrogen gas being injected through a submerged lance. Dephosphorization reaction is analyzed in terms of its reaction equilibrium and stirring intensity or energy involved.<BR>Equation for the dephosphorization equilibrium is established by the extrapolation of the laboratory data at 1 600°C :<BR>logK=(P2O5)/[P]2=1873/T[9.49+8.41log{(CaO)+2.32(Na2O)} - 4.78log(SiO2)] + 5logao+0.26[C] +<BR>36 850/T-25.32<BR>This equation is found to well describe the hot metal dephosphorization all through the treatment. Thus, the reaction is found to proceed very close to the equilibrium.<BR>The effect of the oxygen blow and the stirring upon the dephosphorization is clearly demonstrated. The optimum stirring energy is found to exist for the maximum dephosphorization attainment: between 0.6 to 1.5 MJ/t.
