USA HISTORY

Detailed explanation-1: -In August 1875, the Bessemers at Edgar Thomson made their first blow. Cold air shot through the bottom of the vessels and through the molten iron. The heat increased tremendously, burning out impurities in the iron and forming steel. The process was simple, but the effect was extraordinary.

Detailed explanation-2: -Carnegie adopted a new process invented by Sir Henry Bessemer that allowed steel to be made from iron more efficiently and quickly. This lowered the cost for steel, expanding the market. While this Bessemer steel didn’t work for bridges or buildings, it worked well for railways.

Detailed explanation-3: -The American businessman Andrew Carnegie, during his business trips to England in the years following the Civil War, took special note of the Bessemer process. In 1872 Carnegie visited a plant in England which was using Bessemer’s method, and he realized the potential of producing the same quality of steel in America.

Detailed explanation-4: -The Bessemer Process was the first inexpensive industrial process that allowed for the mass production of steel. Before the development of an open-mouth furnace, the process used a molten pig iron to melt iron. The real difference with this process was that air was forced through the molten iron to remove impurities.

Detailed explanation-5: -Henry Bessemer, Man of Steel Henry Bessemer invented the process that Carnegie used to produce steel. Visit this site to learn more about Bessemer and his achievements in many areas.
