Abstract

A comparative study between the mineral coals used by ArcelorMittal Tubarão has been carried out, aiming at determining complementing criteria to the current energy model for the mineral coals purchasing qualification used for injection in the blast furnace. Material characterization techniques were employed allowing the mapping of the characteristics of the coals which potentially affect the stability of the pig iron production process.
