Iron making process pdf
Webresources – natural gas or coal. This process is known as Direct Reduced Ironmaking (DRI). Carbon combines with the oxygen in the iron ore, producing metallic iron and a carbon-rich process gas, according to the following simplified chemical reaction: 2Fe 2 O 3 + 3C -> 4Fe + 3CO 2 It is also possible to reduce iron ore using hydrogen instead WebThe scrap EAF route is considerably less energy-intensive than producing steel from iron ore (so-called “primary production”) in the BF-BOF or DRI-EAF routes, leading to significant emission reductions without innovation. The main constraint governing this route is the availability of scrap.
