高炉型高钛熔渣离子团结构与粘度的关系

CORRELATION OF ION-CLUSTER STRUCTURE WITH BULK VISCOSITY OF TiO_2-BEARING MOLTEN SLAG

通过含MnO六元钛渣离子团结构模型及结构参数P与熔渣性质的关系,探讨了它们之间的影响规律.结果表明随着熔渣中四配位离子的增加,其体相粘度增加,而六配位离子的作用则相反.熔渣性质与P值相关性很好,可用于熔渣性质报.钛渣变稠是TiO2还原导致P值下降所引起的.

An approach was made to correlate the proposed model of ion-cluster structure and structural parameter of TiO2-bearing 6-system of molten slag with bulk viscosity. Results show that an increase of ions with 4-coordination number in molten slag makes the bulk viscosity increasing, while that with 6-coordination number is contrary. The structural parameter proposed is so fairly interrelated to the properties of slag, that it may be available for the prediction about properties. The reduction of TiO2 in TiO2-bearing molten slag brings the parameter P becoming small and is the basic reason of the bulk viscosity increasing.
