Resumo
There exist three main ways to produce steel from iron ore, namely integrated route via blast furnace and BOF shop, smelting reduction processes like Corex and Finex and BOF shop and direct reduction processes and EAF for smelting. Nevertheless, several new technologies are under development, populating the pipeline of ironmaking technologies that can be adopted in the future. It is not an easy task though. The blast furnace is a very reliable process and has achieved remarkable improvements in the last decades in terms of energy in use, productivity and environmental performance. This paper will give an overview of the status quo of the new ironmaking technologies, discussing their classification according to different criteria, the raw material requirements and expected environmental differentials. Ideas for the future and cost relevant factors are also presented and discussed.
