India possesses large reserves of Low and Medium Volatile Coking coal, which have a potential to produce coke. It is a matter of concern that these coal which accounts to nearly 50% of mineable caking coal reserves have not been able to secure entry into the steel plant due to failure to establish their suitability for coke making. Only high and to some extent medium coking coal is used in the steel sector today. For the long-term security of supply of coking coal to steel plant, it has become essential to examine the potential to use LVMC and medium volatile coking coal in coke making. This can be tried by beneficiating the coal for the improvement of their coking potential for carbonization. Alternately, suitable technology in the form of addition of a blending substance as well as stamping of coal mass prior to carbonization can have potential to improve the coke quality. In the present study an effort has been made to understand the effect of stamping and addition of additives as a binder on LVMC coal charged and analyzing the effect of these parameters on coke quality with respect to its strength, which is accessed by performing different experimental test. Study revealed that there is marked improvement of CRI/CSR value, shatter strength and Graiznov’s strength with optimum stamped coal charged and binder level.
