焦炭反射率与强度指标及反应性之间的相关性
|
摘要
通过控制偏光显微镜的起偏镜旋转角度可以实现焦炭气孔壁平均最大反射率_(max)和平均双反射率bi的自动测定。经回归分析发现,_(max)和焦炭反应性CRI,以及反应后强度CSR之间存在显著的相关关系,相关系数r分别达到-0.926和0.949。_(max)和焦炭机械强度DI_(15)~(150)之间的相关性相对较弱,r为0.704。_(bi_和焦炭各强度指标之间没有发现明显的相关关系。
The mean maximum reflectance _(max) and mean bireflectance bican be measured automatically by controlling the angle of polarizer of microscope. By means of regression analysis,significant the correlationships were found between _(max) and coke reactivity CRI,and coke strength after reaction CSR as well. The values of r were-0.926 and 0.949,respectively. The correlationship between _(max) and coke mechanical strength DI_(15)~(150) was weak obviously,the r of which was only 0.704. No obvious correlationship was found between _(bi) and any other coke property index.
