Detailed explanation-1: -The Bessemer process allowed the mass production of steel, a material that shaped our modern world. The Bessemer process was used in order to produce steel from wrought iron. It changed the steel industry and inspired further developments in steel making. Its impact reached beyond imagination.
Detailed explanation-2: -The Bessemer process revolutionized steel manufacture by decreasing its cost, from £40 per long ton to £6–7 per long ton, along with greatly increasing the scale and speed of production of this vital raw material. The process also decreased the labor requirements for steel-making.
Detailed explanation-3: -The bessemer process reduces molten pig iron in so-called bessemer converters-egg-shaped, silica, clay, or dolomite-lined containers with capacities of 5 to 30 tons of molten iron. An opening at the narrow upper portion of the bessemer converter allows iron to be introduced and the finished product to be poured out.
Detailed explanation-4: -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 being the removal of impurities from iron via oxidisation from air being blown through the molten iron.
