| Abstract: | The thermodynamic behavior of manganese and phosphorus between liquid iron and CaO-MgO-SiO2-A12O3-Fe,O- MnO-P2O5 ladle slag system was addressed by investigating the thermodynamic equilibria between liquid iron containing Mn and P and the ladle slag at 1 873 K. The Mn distribution ratio Lmn increases with increasing FetO content and decreasing the basicity (%CaO + %MgO)/ (%SiO2 + %Al2O3 + %P2O5) in slag, while the P distribution ratio Lp seems to be increased as FetO content and the basicity increases. The values of LM, and Lmn decrease by the addition of A12O3 into slag. The expression of the dependence of Lmn. and Lp on the basicity and FetO content in slag was obtained. |
