Bessemer process

Definition

The Bessemer process is a method for producing steel by blowing air through molten iron to remove impurities. This innovative technique revolutionized steel production in the 19th century, making it cheaper and more efficient, which ultimately fueled advancements in construction, transportation, and manufacturing.

5 Must Know Facts For Your Next Test

1. The Bessemer process was invented by Henry Bessemer in 1856 and was the first method to mass-produce steel efficiently.
2. This process reduced the cost of steel production significantly, allowing for wider use in various industries, including railroads and construction.
3. The introduction of the Bessemer process led to innovations in infrastructure, such as the construction of skyscrapers and bridges that required strong materials.
4. The process works by forcing air through molten iron, which oxidizes and removes carbon and other impurities, resulting in high-quality steel.
5. By the late 19th century, the Bessemer process was largely replaced by newer methods like the open-hearth process but laid the groundwork for modern steelmaking.
