| The Bessemer process, patented in 1855, made mild steel a cheap and superior rival for wrought and cast iron in some products. |
|
| He improved the Bessemer process for making steel, and he was the first to survey British iron ores. |
|
| With the Bessemer process, constantly rising demands for the production of pig iron were able to be met. |
|
| Besides supplying iron to the Sheffield steel trade, Brown himself made improvements on the 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. |
|
| 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. |
|
| 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 Bessemer process involved using oxygen in air blown through molten pig iron to burn off the impurities and thus create steel. |
|
| British and American inventors kept improving on the Bessemer process until the 20th century, when the Siemens-Martin process, which used electrically heated furnaces, became predominant. |
|
| 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. |
|
| Other major components of this infrastructure were the new methods for manufacturing steel, especially the Bessemer process. |
|
| 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. |
|
| Though the Bessemer process was licensed in 1856, nine years of detailed planning and project management were needed before the first steel was produced. |
