Definition: The Bessemer Steel Process was a process of producing high-quality steel by shooting air into molten steel to burn off carbon and other impurities. It was named for the British inventor Sir Henry Bessemer, who worked to develop the process in the 1850s.
English engineer Sir Henry Bessemer (1813â98) patented the process in 1856. In a Bessemer converter, cast iron is converted into steel by blowing air through the molten iron to remove impurities. Precise amounts of carbon and metals are then added to give the desired properties to the steel.
