description | Coke quality depends on the characteristics of the input coal blend and the operating parameters. Very conclusive documentation on the influence of coal blend characteristics and coke mass temperature are available, however, the influence of carbonisation time/slower carbonisation has not been addressed adequately. Experimentation at the stamp charged battery of Tata Steel reveals that increased carbonisation time results in closely sized coke with improved mean size. The coke carbon undergoes significant textural changes. The isotropic carbon content decreases, the amount of coarse and fine mosaic texture increases and the pore diameter decreases. The high temperature properties, coke reactivity index (CRI) and coke strength after reaction (CSR), are improved with longer carbonisation times. |
