Abstract：The blast furnace ironmaking process needs a large number of resources and energy with a great energy saving potential. Iron coke is a highly reactive coke. Iron coke with the appropriate size and amount are mixed with ferrous burden and then charged into the blast furnace. It can lower coke rate theoretically, save scarce coking coal resources and reduce the production cost. The reduction mechanism of the mixed sample is analyzed and the coupling-reaction of iron coke and agglomerates is researched in laboratory, confirming that the mixing of iron coke has an obvious promotion effect on the reduction reaction of sinter and pellets. And increase of temperature and iron coke consumption are benefit for the improvement of iron ores reduction degree.
