    Abstract

    Four kinds of carbon composite iron ore briquette (CCB) were made by mixing two kinds of iron ores and coals that have different properties such as hematite, magnetite, fluidity and non-fluidity coal. The reaction behavior of those CCB was examined at the temperatures of 1273-1473K in N 2 gas atmosphere. The effect of iron ore and coal properties on reaction behavior of CCB was investigated. In the case of CCB that mixed fluidity coal, gasification and reduction rates of the CCB were fast because the contact of iron ore and coal improved. In the case of CCB that mixed hematite ore, reduction rate of the CCB was fast because the reduction rate of hematite ore is faster than that of magnetite ore. Therefore, the reaction rate of CCB that mixed fluidity coal and hematite ore was the fastest in samples.
