Abstract

A comparative study between the mineral coals used byArcelorMittal Tubarão has been carried out, aiming atdetermining complementing criteria to the current energy modelfor the mineral coals purchasing qualification used for injectionin the blast furnace. Material characterization techniques wereemployed allowing the mapping of the characteristics of thecoals which potentially affect the stability of the pig ironproduction process.
