Nippon Steel Carbon Neutral Vision 2050

2021-3-30 · Iron ore needs to be reduced Steelis produced. One ton of steelmaking emits about 2 tons of CO2 Fe2O3 Fe C CO2 Carbon (C) removes the oxygen (O) (reduction) in the iron ore as carbon is more reactive than iron (Fe). In nature, iron exists as oxides, iron ore. To produce steel products, oxygen must be removed (= reduced) from iron ore.

Steel production, from iron and/or recycled scrap, is a multi-stage process which results in the production of a variety of slags.Several of these slags contain hydraulic or latent hydraulic compounds, and can display very good binding properties ...

How is Steel Made? | Metal Casting Blog

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. This process creates equal oxidization throughout the molten metal. Oxidization removes excess carbon.
