The Interactive History of MetallurgyTimeline of metal

Cast iron was unreliable to use for bridges and tracks. This new cheaper and quicker steel production was welcomed by many engineers and designers and soon iron was replaced by steel. A short time later the Siemens Martin process was created. This process was one way to burn off excess carbon from pig iron to produce steel.

Iron Making Boundless World History

It was produced in South and Central Asia during the medieval era but techniques for production of high-quality steel were developed by Benjamin Huntsman in England in the 18th century. However Huntsman s process used iron and steel as raw materials rather than direct conversion from cast iron as in the later Bessemer process.

 · STEEL. Today about 98 percent of pig iron produced worldwide goes into the production of steel the most widely used metal or metal alloy in history. The process begins by pouring molten pig iron into steel furnaces where it is treated to remove any remaining impurities and to lower the carbon content to between 0.1 and 2 percent.

Steelmaking Processan overview ScienceDirect Topics

During the steelmaking process fluxes that consist of lime (CaO) or dolomitic lime with iron and scraps are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime with a specific gravity of 3.34 can react with water to produce Ca(OH) 2 with a specific gravity of 2.23 which results in volume increase (Fig. 9.1).

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.
