Abstract

In order to reduce CO₂, emission and cope with the shortage of agglomerated ore due to the use of low-grade iron ore for a sintering process, which are key issues in the ironmaking field, it was proved that direct reduced iron can be manufactured using comparatively cheap fine iron ore and coal, or steel mill waste as the raw material. By using coal-based direct reduced iron, hot briquetted iron (HBI) which has sufficient strength for blast furnace use was manufactured in the demonstration plant. The use of this HBI in the blast furnace could contribute to reduce CO₂, emission and dealing with the shortage of agglomerated ore.
