USA HISTORY

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: -Bessemer process, the first method discovered for mass-producing steel. Though named after Sir Henry Bessemer of England, the process evolved from the contributions of many investigators before it could be used on a broad commercial basis.

Detailed explanation-3: -Patented in 1855, the Bessemer process decreased the cost of steel from £50–60/t ($80–95/t) to £6–7/t ($9–11/t), hand-in-hand with vast increases in scale and speed of steel production. Steel girders for bridges, buildings, railroads, skyscrapers – all were unimaginable before Bessemer.

Detailed explanation-4: -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.
