摘要：The aim of this work was to characterize cokes optical texture influence of plastic properties of coal blendson degree of cokes optical texture ordering. Three samples of coal blend characterized by different composition andproperties were pyrolysed in Karbotest furnace (laboratory scale). To characterize plastic properties of the blends studied,temperatures at the beginning, maximum and at the end of plasticity (t1, tmax and t3, respectively) were determinedas well as maximum fluidity Fmax. Texture of resultant cokes was determined by means of optical microscopy. As theresult of these studies a set of optical parameters that describe reflectance indicating surface such as maximum, intermediateand minimum reflectance (RMAX, RINT, RMIN respectively) as well as values of Killby’ transformates (Rst, Ram,Rev) were determined for each sample. The optical texture parameters of the cokes were discussed in relationship toplastic properties of coals blends. Correlation between cokes anisotropy and fluidity of initial blends was detected.
