Fortunately for the ironmasters, a new technology, named for its English inventor, Henry Bessemer, became available in the postwar years. |
|
The Bessemer process, patented in 1855, made mild steel a cheap and superior rival for wrought and cast iron in some products. |
|
The open-hearth process of steel-making allowed the operator a greater amount of control over materials used in the mills' heat than did the older Bessemer process. |
|
The Basic Bessemer process is used a great deal on the Continent for making, from a very suitable pig iron, a cheap class of steel, e.g. ship plates, structural sections. |
|
For example, in 1850 the steel making industry was drastically changed by the Bessemer process which burned out impurities in iron through the use of a blast furnace. |
|
The result was a new, hard metal, Bessemer steel, ideal for rail-making. |
|
The puddling process began to be displaced with the introduction of the Bessemer process, which produced steel. |
|
The modern era in steelmaking began with the introduction of Henry Bessemer's Bessemer process in 1855, the raw material for which was pig iron. |
|
Henry Bessemer worked on the problem of manufacturing cheap steel for ordnance production from 1850 to 1855 when he patented his method. |
|
The Bessemer process involved using oxygen in air blown through molten pig iron to burn off the impurities and thus create steel. |

Sheffield's Kelham Island Industrial Heritage Museum maintains an early example of a Bessemer Converter for public viewing. |
|
Originally made from Bessemer steel, following the closure of the Moss Bay Steelworks, steel for the plant was brought by rail from Teesside. |
|
This process was rendered obsolete in 1856 by Henry Bessemer's invention of the Bessemer converter. |
|
The Crawshays refused to modernise by replacing iron production with steel production, using the newly discovered Bessemer process. |
|
Earlier processes for this included the finery forge, the puddling furnace, the Bessemer process, and the open hearth furnace. |
|
In the late 1850s, Henry Bessemer invented a new steelmaking process, involving blowing air through molten pig iron, to produce mild steel. |
|
Other major components of this infrastructure were the new methods for manufacturing steel, especially the Bessemer process. |
|
It involved taking molten steel from a Bessemer converter and pouring it into cooler liquid slag. |
|
Bessemer steel was being displaced by the open hearth furnace near the end of the 19th century. |

A reluctant patentor, and in this instance still working through some problems in his method, Nasmyth abandoned the project after hearing Bessemer at the meeting. |
|
One of the most significant innovators of the Second Industrial Revolution, Bessemer also made over 100 other inventions in the fields of iron, steel and glass. |
|
Though the Bessemer process was licensed in 1856, nine years of detailed planning and project management were needed before the first steel was produced. |
|
Bessemer was knighted by Queen Victoria for his contribution to science on 26 June 1879, and in the same year was made a fellow of the Royal Society. |
|
Bessemer had been trying to reduce the cost of steelmaking for military ordnance, and developed his system for blowing air through molten pig iron to remove the impurities. |
|
Bessemer licensed the patent for his process to five ironmasters, but from the outset, the companies had great difficulty producing good quality steel. |
|
The first Bessemer steel rail was made at Dowlais in 1856 and, by the turn of the century, the company had launched its steel works and plate mill in Cardiff. |
