Steps in the Modern Steelmaking Process
Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.
Steelmaking - Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygenand entrained impurities (termed "inclusions") in the steel is also important to ensure the quality of the produ…
Bessemer process - Wikipedia
The process also decreased the labor requirements for steel-making. Before it was introduced, steel was far too expensive to make bridges or the framework for buildings and thus wrought iron had been used throughout the Industrial Revolution. After the introduction of the Bessemer process, steel and wrought iron became similarly priced, and ...

Steel making process – ArcelorMittal
Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron
How is Steel Produced? | World Coal Association
Global steel production is dependent on coal. 70% of the steel produced uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was 1.8 billion tonnes in 2018.
COREX Process | Iron Making | Iron Steel Review | …
Compared with the traditional iron making process via the blast furnace route, the COREX process differs since non coking coal can be directly used for ore reduction and melting work, eliminating the need for coking plants. The use of lump ore or pellets also dispenses with the need for sinter plants.

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.
Steel manufacture - SteelConstruction.info
Making iron [] Conversion to steeThe basic raw material for steel manufacture is either the hot metal from the blast furnace, steel scrap or a mixture of both.The proportions of material used vary according to the process and the type of steel required.
Steelmaking Process - an overview | ScienceDirect …
Iron and steelmaking process is energy intensive. Generally speaking, energy constitutes a significant portion of production cost, from 20% to 40%, according to the estimation from world steel association [7].About 95% of energy for an integrated steelmaking plant comes from solid fuel (mainly coal), 3–4% from gaseous fuel and 1–2% from liquid fuel.
A Short History of Steel and the Bessemer Process
Blister steel—one of the earliest forms of steel—began production in Germany and England in the 17th century and was produced by increasing the carbon content in molten pig iron using a process known as cementation. In this process, bars of wrought iron were layered …
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.
