High-Carbon Hot DRI Production and Use: ENERGIRON Results and Performances in Operating Plants

摘要

The performance requirements for modern steelmaking facilities are ever more stringent, as customers and markets are continuously pushing for technologies which allow having high quality steel produced in an economic and sustainable way.The BF-BOF, using directly iron ore as raw material for steel production, is for sure a change for producing high grade steel; nevertheless, using coal as reducing agent, the significant amount of CO_2 emitted in the atmosphere as byproduct of the reduction reactions, combined with the low energy efficiency of this process, contributes to make this route often incompatible with restrictions imposed by environmental regulations and less competitive.
