Two processes, basic oxygen steelmaking (BOS) and electric arc furnaces (EAF), account for virtually all steel production.www.thoughtco.com/steel-production-2340173Modern Steelmaking: Today, steel is primarily produced through two main processes: the basic oxygen furnace (BOF) and the electric arc furnace (EAF). In the BOF process, molten iron from a blast furnace is combined with scrap steel and oxygen to produce steel.www.stellasource.com/what-is-steel-how-is-steel-m…A total of around 70% of steel is produced using the BF-BOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF. After casting and rolling, the steel is delivered as coil, plate, sections or bars.worldsteel.org/about-steel/what-is-steel/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.www.reliance-foundry.com/blog/how-is-steel-made
