  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 with powdered charcoal in stone boxes and heated. iron, they began producing steel. More than 4, years ago, people in Egypt and Mesopotamia discovered meteoric iron and used this ‘gift of the gods’ as decoration. But it was another 2, years before people began producing iron from mined iron ore. The earliest finds of smelted iron in India date back to Before Common Era (BCE).   At very high temperatures, iron begins to absorb carbon, which lowers the melting point of the metal, resulting in cast iron ( to % carbon). The development of blast furnaces, first used by the Chinese in the 6th century BC but more widely used in Europe during the Middle Ages, increased the production of cast iron. When trying to produce steel, there are some difficulties compared to gold or bronze. So, it is not surprizing that it came latter in History. In the America, for example Incas and Mexicans used gold and silver but didn’t have iron mettalurgy (wha.

  A source of info would be "Steel Making Before Bessemer, vol 1 Blister Steel, vol 2 Crucible Steel" (need to check that title when I get home) Also "Mechanics Exercises" by Joseph Moxon discusses the various wrought iron available around and what each was good for. developed independently by the British manufacturer Henry Bessemer and American iron maker William Kelly = a cheap and efficient process for making steel, developed around = soon became widely used = the technique involved injecting air into molten iron to remove the carbon and other impurities (removing the carbon from iron produces a lighter, more flexible, and rust - resistant metal. stages: 1) coke use in the blast furnace, 2) puddling process for wrought iron (WI) and 3) Bessemer or Siemens processes for steel. The second gave rise to the conversion from wooden (iron-reinforced) machines to iron machines such as railroad engines, ships and long-span bridges, all hot-riveted. of iron and steel, the rest of the book examines their physical properties and metallurgy. production of compacted Graphite Irons, Ductile Iron, Malleable Cast Iron and current status of steel making together with the reasons for obsolescence of Bessemer converter and open hearth processes, the book Bessemer Process.

The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. The process was patented in , though iron companies initially failed to produce the high-quality steel they’d expected; excess oxygen left the steel brittle and it was difficult to retain the right quantity (of between –% by weight) of carbon in the steel. Bessemer’s solution, which was to stop the airflow before all the carbon. Iron processing, use of a smelting process to turn the ore into a form from which products can be ed in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth’s crust, and it is the.   About a decade before Sidney Thomas refined the Bessemer Converter with a lime-based lining, Carnegie brought the Bessemer process to America and acquired phosphorus-free iron to produce steel.
