Effect of Carbonization Time on Hot Properties of Blast Furnace Coke

Very conclusive document for the influence of coal blend characteristics and coke mass temperature on coke quality are available,however,the influence of carbonization time has not been addressed adequately.Experimentation at the stamp charged battery of Tata Steel reveals that increased carbonization time results in closely sized coke with improved mean size.The coke carbon undergoes significant textural change.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 carbonization time.
