INFLUENCE OF BURDEN DISTRIBUTION ON COUPING EFFECT OF IRON ORE REDUCTION AND COKE GASIFICATION IN BLAST FURNACE LUMP ZONE

摘要

Recently, the improvement of coupling effect of iron ore reduction and coke gasification reactions have been concerned much in order to decrease reducing agent rate in blast furnace. High reactive coke could improve the reduction efficiency of iron ores in lump zone significantly, which has also been proved in our former study. Therefore, in this paper the influence of burden distribution (includes layered and mixed distributions) on coke gasification and iron ore reduction was laboratory investigated by using high reactive coke.
