Direct reduced iron plant
A Direct Reduced Iron plant is a furnace that produces Direct Reduced Iron (DRI), also referred to as sponge iron due to its porous nature. The process can also produce Hot Briquetted Iron (HBI). The iron can then be used to produce steel via other production routes, such as the Electric Arc Furnace (EAF). The process uses iron ore (in the form of lumps, …
