    Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based the same premise as the Bessemer Process, namely, how to most efficiently use oxygen to lower the carbon content in iron. Modern steelmaking can be broken down into six steps: 1. Ironmaking: In the first step, the raw inputs iron ore

    Steel Manufacturing Processes. Most steel is produced using one of four methods: Bessemer converters, open-hearth furnaces, basic oxygen furnaces, and electric furnaces. The basic oxygen process is the most efficient, while the Bessemer and open-hearth methods have become obsolete. Electric furnaces are used to produce high quality steels from selected steel scrap, lime, and mill

    Steel is simply low-carbon iron. As such, the steel manufacturing process begins by smelting iron ore (Fe 2 O 3 or Fe 3 O 4) in a blast furnace. This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and
