| 摘 要： | 根据炉渣结构的共存理论用回归分析法确定了MnSiO3和Mn2SiO4是存在于MnOSiO2渣系中且参加其内部化学反应的组元。由此得出本渣系的结构单元为Mn2+,O2-简单离子和SiO2,Mn2SiO3,Mn2SiO4分子,进而推导出本渣系各组元作用浓度的计算模型。 在1600℃下计算的NMnO与实测aMnO一致;但在高MnO含量和低温度下两者间表现出差别,这是由于MnO-SiO2渣系中出现两相共存的现象,使系统远离平衡所致。 |

| Abstract: | In accordance with the coexistence theory of slag structure and by means of regression analysis,the presence of MnSiO3 and Mn2SiO4 in the slag system MnO-SiO2(and that both of them take part in the reaction of this system) has been determined,therefore the structural units of this system can be expressed as simple ions Mn2+O2-and molecules SiO2,MnMnSiO3,Mn2SiO4 and the calculating model of mass action concentrations can also be written. At 1600℃ the calculated values of NMnO are identical with the measured αMnO,but the differences; between them at high concentrations of MnO and ower temperatures are due to the coexistence of liquid and solid in the slag system MnO-SiO2,which makes it departure from equilibrium. |
