Conventional technology based on BF/BOF operations has been the backbone of steel production. The pre-eminence of these high quality steelmaking operations is being challenged by EAF-based mini mills charging varying amounts of AIUs, primarily pig iron and DRI/HBI, with significant quantities of scrap.

metal iron content by directly reducing iron ore (or iron ore pellets) with reducing gases. While the produced DRI is mainly used as the raw material of electric steelmaking, it is also used as blast furnace feed for energy saving (reduction in coke consumption) and increased production of molten iron at integrated blast furnace steelworks.
