Detailed explanation-1: -The Bessemer process allowed steel to be produced without fuel, using the impurities of the iron to create the necessary heat. This drastically reduced the costs of steel production, but raw materials with the required characteristics could be difficult to find.
Detailed explanation-2: -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-3: -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.
Detailed explanation-4: -The Bessemer Process was the first inexpensive industrial process that allowed for the mass production of steel.
Detailed explanation-5: -British inventor Henry Bessemer’s creation of the Bessemer converter was a major advancement for steel making. Prior to his work, steel was scarce, made through a costly and arduous process. His technique prompted a revolution in manufacturing.
