Steel - Bessemer steel | Britannica
Steel - Steel - Bessemer steel: Bulk steel production was made possible by Henry Bessemer in 1855, when he obtained British patents for a pneumatic steelmaking process. (A similar process is said to have been used in the United States by William Kelly in 1851, but it was not patented until 1857.) Bessemer used a pear-shaped vessel lined with ganister, a refractory material containing silica

Steps in the Modern Steelmaking Process
14/1/2020· Primary steelmaking has two methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%.
