Abstract
INVESTIGATIONS has been carried out to find the optimum conditions for the production of highly reduced iron ore briquettes suitable as a blast furnace feed from Indian ore fines and low grade coke/wool charcoal under reduced pressure 1 x 101 mm. (Hg.) The effects of time (1/4 hr. to 6 hr.) temperature (950°C to 1150°C and Fe20 1,C ratio (1/3 to 1/5) on the rate of reduction of iron ore brique-ttes have been studied. From the kinetic results, a mecha-nism for reduction of iron oxide in iron ore briquettes is proposed and optimum conditions for production of highly reduced iron ore briquettes are summarised.
