The future of steelmaking - Roland Berger

It involves processing iron ore to produce iron sinter or pellets, and then melting these in a blast furnace (BF) with coke to make pig iron. This is processed in a basic oxygen furnace (BOF) to create steel. The rest of Europe's steel comes from the secondary route. It produces steel from scrap metal by heating it in an electric arc furnace (EAF).
