Steps in the Modern Steelmaking Process

 · 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. Today, steel production makes use of recycled materials as well as traditional raw materials, such as iron ore, coal, and limestone.

Iron and Steel – Analysis

Scrap-based production (also referred to as secondary or recycled production) can be valuable in reducing energy demand and CO 2 emissions, as it is considerably less energy-intensive than primary production from iron ore. Scrap is used as the main ferrous feed in electric arc furnaces (EAFs), as well as in induction furnaces to a lesser extent.

Iron Ore | Geoscience Australia

Iron Ore. Iron (Fe) is a metallic element which constitutes about 5% of the Earth''s crust and is the fourth most abundant element in the crust.

Iron Ore

Iron Ore. The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a ''high-grade'' ore, and banded metasedimentary ironstone, magnetite-rich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite and taconite which provide a ''low-grade'' ore.

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. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle ...
