Extraction of iron and its conversion into steel ... The coke (essentially impure carbon) burns in the blast of hot air to form carbon dioxide - a strongly exothermic reaction. This reaction is the main source of heat in the furnace. ... It is the carbon monoxide which is the main reducing agent in the furnace.
