CaO-SiO_2-Fe-O体系熔馆体的温度-粘度关系已经确定,其数值可与那些组成中代替Si~(4十)的是Al~(3+)而不是Fe~(3+)的类似熔体对比.温度在液相线之上时,含铁熔体粘度的变化范围在5和15泊之间,作为Ca/Si、铁含量和温度(1400—1600℃)的函数,这些熔体粘滞流的活化能在8—50千卡/摩尔之间.与无铁熔体相比,当加入5%(重量)Fe_2O_3时,含铁熔体的粘度值明显增加,如继续加入三价铁就会引起这一趋势的逆转.恒温时,粘滞流的活化能随Fe~(3+)含量的增加而减小,当铁含量固定时,活化能则随温度的增加而减小.而已发表的CaO-Al_2O_3-SiO_2体系熔体的粘度数据表明,随Al_2O_3含量的增加,其粘度值持续增加.这些
The temperature-viscosity relationship of the CaO-SiO 2 -Fe-O system has been determined, and its value can be compared with those of Al 3+ rather than Fe 3+ in those compositions that replace Si 4+. Analogous to melt comparison, the viscosity of the ferrous melt varies between 5 and 15 poises as the temperature is above the liquidus, and as a function of Ca / Si, iron content and temperature (1400-1600 ° C) these melts The viscosities of bulk viscous flow are between 8 and 50 kcal / mol.When adding 5 wt% Fe 2 O 3, the viscosity of iron-containing melt increases obviously compared with that of non-iron melt, When the iron content is fixed, the activation energy decreases with the increase of the temperature. When the iron content is constant, the activation energy of the viscous flow decreases with the increase of the Fe 3+ content. However, the viscosity data of the published CaO-Al 2 O 3 -SiO 2 system showed that the viscosity of the melt increased with the increase of Al 2 O 3 content
