The coal petrography of 13 different rank single coals and the quality of cokes made on 40 kg pilot coke oven were measured and analyzed in the paper.The results indicated that the relationship between optical texture index of coke(OTI) and vitrinite mean maximum reflectance of single coal was positive linear correlation.By multiple linear regression analysis,the quantitative relationship between vitrinite reflectance distribution and the component of coke optical texture were determined;The influence of... 相似文献

Morphology,distribution and crystal structures of age-precipitated particles in practical Cu-bearing steels with ultra-low carbon were studied by high resolution electron microscopy(HREM).The age-precipitation behavior was explored when poly-microalloying elements Cu,Nb,Cr,Mo and Ni were used and ε-Cu particles coexisted with carbides(carbonitrides) in steels.The fine dispersed ε-Cu particles and carbides of microalloying element Nb,Cr,Mo being about 10 nm only in size were observed in peak aging specimens ... 相似文献
