Steps in the Modern Steelmaking Process
14/11/2019· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.
Creating Steel HowStuffWorks
Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.

The most commonly applied process for steel-making is the integrated steel-making process via the Blast Furnace Basic Oxygen Furnace. In the basic oxygen furnace, the iron is combined with varying amounts of steel scrap (less than 30%) and small amounts of flux. A lance is introduced in the vessel and blows 99% pure oxygen causing a
How is Iron Made Into Steel? Sciencing
Iron was the dominant metal for use in building and machinery until the modern era. Iron is still the main component of steel but when impurities are removed in the steel-making process, a stronger, lighter material results (steel). Steel is used in almost all modern buildings, automobiles, aircraft and appliances.

How Is Cast Iron Made? Sciencing
24/04/2017· Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this
Steel production & environmental impact
Steel is ‘iron with most of the carbon removed’ Iron constitutes about five per cent of the Earth's crust and is the fourth most abundant element in the crust. 98% of the iron ore mined is used to make steel; Steel represents around 95% of all metals produced
