Details >Mar 26, 2020· The blast furnace reduces iron from the iron oxide, but the complete reduction reaction requires the addition of coke and limestone to the roasted ore. After the completion of different processes in the blast furnace, molten iron flows from the bottom of the blast furnace. This molten iron may be utilized as cast iron.
