Abstract

The effects of coal and iron oxide properties on the reaction behavior of carbon composite iron ore briquettes were investigated at the temperatures of 1273-1473K in N₂ atmosphere. Four kinds of carbon composite iron briquettes were prepared in combination with two iron ores (hematite ore, magnetite ore) and two coals (high fluidity coal, low fluidity coal). The gasification rates and reduction rates of the samples contain high fluidity coal were faster than those of the samples contain low fluidity coal because of the better adhesiveness between iron ore and coal. The reduction rates of the samples contain hematite ore were faster than those of the samples contain magnetite ore because the reduction rate of hematite is faster than that of magnetite. The reaction rate of the sample consists of hematite ore and high fluidity coal was the fastest in the samples.
