Direct reduced iron (DRI) can be used after briquetting in form of HBI in the blast furnace to decrease the consumption of reducing agents as well as to increase the production of hot metal. voestalpine Stahl GmbH Linz uses HBI from its own plant in Corpus Christi (Texas) at the blast furnaces 5 and 6. In this article the influence of the usage of HBI in the blast furnaces on the consumption of reducing agents, productivity, blast furnace operation and hot metal quality is discussed.
