Effect of coalchar reactivity & reduction temperature on the reduction behaviour of iron ore

Abstract

In the present investigation , an attempt has been made to study the effect of coal char reactivity and reduction temperature on the reduction behaviour of iron ore pellet. The reduction tests were conducted in the temperature range of 900-950 degree centigrade. The parameters studies were the reduction temperature and coal char reactivity.The experiments were statistically designed such that the effect of each variable and interactional effect of each variable can be quantitatively assessed and compared.The results showed highest degree of reduction coal char having high percentage of fixed carbon content.
