Ferro-coke | Challenge Zero

Ferro-coke is an innovative material for a blast furnace which improve reduction reaction of iron ore inside the blast furnace and resulting in significant reduction of CO 2 emission. Ferro-coke is a hybrid agglomeration of coke and metallic iron which are produced from coal and iron ore by crushing, mixing, formed and heated in a continuous carbonizing furnace.

Iron making - SlideShare

Mar 02, 2013· The density of three important raw materials viz. the ore, the coke and the limestone are quite different. The heaviest is iron ore with around 5-6 glcc, the lightest is coke with density of around 1·5 glcc and the limestone is intermediate with-a value of density around 3·0-3·5 glcc. It means that the rolling tendency of coke particles is ...
