The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron The oxidation also raises the temperature of the iron mass and keeps it molten

May 16, 2019 The Modern Steel Production Process Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron

Aug 12, 2018 Open hearth process also called the regenerative open hearth: A bit like a giant fireplace in which pig iron, scrap steel, and iron ore are burned with limestone until they fuse together More pig iron is added, the unwanted carbon combines with oxygen, the impurities are removed as slag and the iron turns to molten steel

Iron and Steel HIGHLIGHTS PROCESSES AND TECHNOLOGY STATUS The basic materials for iron production are iron ore, coal and coke also used as energy input to the process or alternative reducing agents, limestone and dolomite Steel production requires iron, steel

Modern day steel production makes use of both traditional raw materials iron and recycled materials to turn them into steel With this in mind, here are the 6 steps to modern steel production explained Step 1 The iron making process As iron is the main component of steel it firstly needs to be made

Steel production is a 24 hour a day, 365 day a year process, dependent on a consistent supply of raw materials and huge amounts of energy According to the World Steel Association, world crude steel production has increased from 851 million tonnes Mt in 2001 to 1,606 Mt in 2013 and world average
