| 摘 要： | 根据冶金熔体的共存理论，计算了CaO-MgO-MnO-FeO-SiO2-Al2O3六元渣系各组元的作用浓度。结合生产实际数据，建立了LF精炼过程中精炼渣成分和w［Al］之间氧化还原反应的数学模型，计算了精炼渣成分对w［Al］的影响。结果表明，LF精炼过程中w［Al］受w［Si］、w(FeO)联合控制。低碱度、低Al2O3含量的精炼渣对控制w［Al］有利，如果精炼渣碱度控制在0. 9，Al2O3含量(质量分数，下同)控制在3%以下，则可以将w［Al］控制在6×10-6以下。适当提高FeO含量有利于降低w［Al］。 |

| Abstract: | According to the coexistence theory of slag structure, mass action concentrations for CaO-MgO-MnO-FeO-SiO2-Al2O3 slag were calculated. Based on the practical data, a mathematical model of oxidation-reduction of ［Al］ under some slag conditions in LF refining process was built. The influence factors about ［Al］ contents with different slag compositions were calculated. The results show that the ［Al］ contents can be controlled by w［Si］ and w(FeO). The refining slag of lower basicity and w(Al2O3) is advantageous to control ［Al］ contents, and it should be controlled under 6×10-6 when the refining slag basicity is 0. 9 and w(Al2O3) within 3%. The ［Al］ contents would be reduced when w(FeO) is appropriately raised. |
