Abstract
Experiments have been made to study the phosphorus distribution between carbon-saturated iron and lime-based melts containing MnO, BaO, Na2O in the temperature range of 1250-1350°C under a CO atmosphere.The results are summarized as follows:(1) The phosphorus equilibrium distribution between CaO-CaF2 SiO2-MnO melts and carbon-saturated iron decreases with increasing manganese oxide content in slaps.(2) BaO and Na2O have a beneficial effect on the phosphate capacity of the slags for the systems: CaO-CaF2-SiO2-MnO-BaO and CaO-CaF2-SiO2-MnO-Na2O.(3) Increasing CaF2 content in the range of 25 to 40% decreases the phosphorus equilibrium distribution.(4) The temperature dependence of equilibrium phosphorus distributions can be expressed as follows: log Lp=13300/T-8.84The heat of reaction of dephosphorization was -130kcal per mole of Ca1.5PO4.
