The Bessemer Steel Process ThoughtCo

Updated on April 01 2024 The Bessemer Steel Process was a method of producing high quality steel by shooting air into molten steel to burn off carbon and other impurities It was named after the British inventor Sir Henry Bessemer who worked to develop the process in the 1850s

How is Steel Made Metal Casting Blog Reliance Foundry Co Ltd

At the most basic steel is made by mixing carbon and iron at very high temperatures above 2600°F Primary steelmaking creates steel from a product called pig iron Pig iron is smelted iron from ore which contains more carbon than is correct for steel The steelmaker uses a system that bubbles oxygen through melting pig iron
