USA HISTORY

Detailed explanation-1: -The invention of the open-hearth (Siemens-Martin) process in the late 1860s eventually outstripped that of the Bessemer process. This has now yielded place, in great measure, to oxygen steelmaking, which is a further development and refinement of the Bessemer process.

Detailed explanation-2: -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.

Detailed explanation-3: -1.1. From a small-scale output of pig-iron, major developments in steel production took place during the second half of the 19th century. The Bessemer process (1855) made it possible to produce steel as ingots.

Detailed explanation-4: -The engineer and inventor Henry Bessemer revolutionised steel production thanks to an air-based iron decarbonization system. He was able to cut costs and manufacture a stronger and lighter steel on a large scale. A breakthrough that fueled the expansion of the railroad and marked the birth of modern cities.

Detailed explanation-5: -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. He was knighted in 1879.
