摘要

Were studied in this paper the most relevant effects of pulverized coal injection in blast furnaces using charcoal, the influence in the main process parameters, such as carbon consumption through top and total, theoretical flame temperature and productivity of the blast furnace. The blast furnace worked during the period analyzed with 100% lump ore.
