Define the Bessemer process

The Bessemer process is a method of converting iron into steel by blowing air through molten iron to remove impurities and lower the carbon content. It was developed by Sir Henry Bessemer in the 19th century and played a crucial role in the industrialization and mass production of steel. The process revolutionized the steelmaking industry by significantly reducing the time and cost of production, thus making steel more affordable and widely available for various applications.
