2 天前  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

Emerging Technologies for Iron and Steelmaking

The iron and steel industry has undergone a technological revolution in the last 40 years. In a relatively short time, the North American industry has observed the complete disappearance of basic open hearth processing, as well as the wide spread adoption of continuous casting and the near complete shift of long product production to the electric arc furnace sector.
