Abstract:At the ratio of iron ore powder of 10%, the influence of Canadian iron ore powder, Australian iron ore powder and E-Xi iron ore powder on reactivity, reaction beginning temperature and activation energy, etc. of iron cokes are researched systematically. The results show that, the reaction beginning temperatures of iron cokes decrease obviously, the decreasing extent depends on the type and property of iron ore powder; the mechanism should lie in the iron ore powders which make the activation energy of the iron cokes decreases and lead to reactivity of iron cokes increase; and the correlation among reaction beginning temperature, activation energy and reactivity is very well.
