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'' - still

A Comparison of Blast Furnace and Corex Routes for Iron …
Iron-making provides a vital engineering input in the process of steel production. This requires huge investment and hence, selection of an appropriate iron-making technology is very crucial in a capital scarce country like India. However, in this arena Blast furnace (BF) technology is considered as proven and the dominant one. Meanwhile, a new technology named Corex has emerged in this field
