6 Steps of Modern Steelmaking Process 3MVET

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, coke, and lime are melted in a blast furnace. The resulting molten iron - also referred to as 'hot metal' -

iron processing - Iron making Britannica

iron processing - iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
