  • The future of steelmaking - Roland Berger

    2 天前 · The majority of European steel (60%) is made via the primary route. 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.
