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' - still ...
Feb 15, 1996· Steel making stages. Steel is made in three stages: melting, refining and teeming. Molten steel is poured twice during processing. The first pouring takes place after melting, when the steel is transferred from the melting to the ladle furnace. This procedure is called tapping. After refining, the steel is poured into moulds.
