Session: DRI as an alternative raw material for iron and steelmaking (applications in blast furnace, EAF etc.)

Integration of DRI plants into classical BOF production sites

The production of quality flat steel products is commonly linked to highly integrated sites which include Hot metal generation via the Blast Furnace route, Oxygen Steelmaking (BOF), Continuous Casting, and subsequent Hot Rolling. Modern DRI plants offer various new opportunities to these sites, especially a wide reduction in CO2 emissions. Nevertheless, the implementation of direct reduction units into integrated metallurgical plants include various challenges. Different approaches have been suggested and will be discussed. Metallurgical aspects need to be considered to maintain product quality which reflect customer demand. Effects on the sites internal and external energy network and on site logistics have to be evaluated and handled. The findings presented can help to tailor solutions on how to integrate DRI plants into the classical flat steel production route.
