Why Use Coke for Blast Furnace Ironmaking not Use Coal

Reduction: The coke carbon content is above 85%. The high-temperature CO2 gas reacts with the carbon in the coke to form CO, and the CO further reduces the iron ore to form molten iron. Carbon supply: The carbon content of pig iron is about 4%, all from blast furnace coke, accounting for 7%-9% of coke carbon content.
