Steel production causes significant emissions of carbon dioxide. To decarbonize steel production and its high carbon dioxide emissions, Fraunhofer researchers, TS ELINO and Salzgitter AG are working on converting an existing steel mill to climateneutral production methods. The aim is to produce steel by the direct reduction of iron ore with hydrogen, which would completely replace ...

Abstract. The use of sinter influences hot metal production substantially and significantly affects an integrated steel mill's total emissions. Sintering of iron ores is an enormous energyintensive and resources consuming process. Introducing a selective waste gas recirculation (SWGR) to the sintering process reduces the energy consumption ...

Another factor has received less attention. DRI steelmaking requires a higher grade of iron ore than blast furnaces, the dominant global process. DRgrade iron ore ideally has an iron (Fe) content of 67% or more and such deposits are scarce only a small percentage of global seaborne iron ore comes close to DRgrade.

At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.
