2019-8-1  In this method, the pig iron is combined with scrap steel (roughly below 30%) together with a small amount of flux. Oxygen is then blown into the furnace raising the temperature to an excess of 1700˚. The pressurised oxygen reacts with the pig iron (containing high levels of carbon) and the scrap, forming CO in addition to CO2.

How is Steel Made? Metal Casting Blog

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.
