Brief introduction of Sponge Iron
Sponge iron can be converted into hot briquetted iron (HBI) for easier transportation or storage. However, it is difficult to carry the agglomerate, which is the blast furnace feed. In the process of direct reduction, natural gas can be used without removing its impurities. Related products: Sponge Iron; Iron Pellet
