The physico-chemical properties of coke produced by adding 25% imported coal or 5-12% solvent refined coal to an industrial coking blend are discussed. The importance and significance of post-reaction strength of coke on coke rate on blast furnace productivity in a typical steel plant been alalysed. The favourable results with respect to the above have been projected in economic terms by cost-benefit analysis. In the case studied, even 5% SRC addition to the coking blend brings out an extra savings of Rs. 755 million per annum compared to use of 25% imported coal in the blend due to savings in coke rate and enhancement in productivity of the blast furnace because of lower ash and better post-reaction strength of the coke. It is also envisaged that if 10% SRC is used in the blend this extra savings would rise up to Rs. 3711 million per annum. If this finding is extended to all the steel plants in the country enormous savings in terms of foreign exchange are foreseen.
