| 英文摘要 | The coupling relationships between dephosphorisation and desulphurisation abilities or potentials for CaO-FeO-Fe2O3-Al2O3-P2O5 slags during secondary refining process of molten steel have been proposed as logL(P) + 5logL(S) or logC(PO43-) + log(C)(S2-) in reducing zone at oxygen potential p(O2) less than 2.27 x 10(-6) Pa as well as logL(P) + logL(S) - 5logN(Fe,O) or logC(PO43-) + log(C)(S2-) - logN(FeO) in oxidising zone at oxygen potential p(O2) greater than 2.27 x 10(-6) Pa through deleting slag oxidisation ability expressed by the comprehensive mass action concentration N-Fe,(O) of iron oxides based on the ion and molecule coexistence theory (IMCT). The proposed coupling relationships between dephosphorisation and desulphurisation abilities or potentials of the slags have been verified to be valid using reported data of oxygen, phosphorus and sulphur distribution equilibria between the slags and liquid iron over a temperature range from 1811 to 1927 K (1538-1654 degrees C) and predicted results of dephosphorisation and desulphurisation abilities or potentials. Not only the proposed coupling relationships between dephosphorisation and desulphurisation potentials but also the correlated coupling relationships between dephosphorisation and desulphurisation abilities for the slags in reducing and oxidising zones have been verified to be indeed independent of slag oxidisation ability. |
