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: -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: -Henry Bessemer, in full Sir Henry Bessemer, (born January 19, 1813, Charlton, Hertfordshire, England-died March 15, 1898, London), inventor and engineer who developed the first process for manufacturing steel inexpensively (1856), leading to the development of the Bessemer converter.

Detailed explanation-4: -In the mid 1850s a man named Henry Bessemer invented the Bessemer Process, which is a way to manufacture steel quickly and cheaply by blasting hot air through melted iron to quickly remove impurities. Thanks to the Bessemer Process steel started being produced in 10 or 20 minutes!

Detailed explanation-5: -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.
