Eduion:The Bessemer Process - Engineering and …
Englishmen, Sir Henry Bessemer (1813-1898) invented the first process for mass-producing steel inexpensively, essential to the development of skyscrapers. An American, William Kelly, had held a patent for "a system of air blowing the carbon out of pig iron" a method of steel production known as the pneumatic process of steelmaking.
The process casts molten steel directly into sheet steel at or near its final thickness, eliminating the need for large hot and cold rolled reductions. Compared to the casting and rolling process of an integrated steelmaking facility, the Castrip process consumes about 95 percent less energy and emits less than one-tenth the greenhouse gases.
