Bessemer process

Bessemer converter, schematic diagram

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 furnace. The 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 modern process is named after its inventor, the Englishman Henry Bessemer, who took out a patent on the process in 1856.[1] The process was said to be independently discovered in 1851 by the American inventor William Kelly[2][3] though the claim is controversial.[4][5][6][7]

The process using a basic refractory lining is known as the "basic Bessemer process" or Gilchrist–Thomas process after the English discoverers Percy Gilchrist and Sidney Gilchrist Thomas.
