In addition to producing feedstock for its own blast furnaces, the mill also supplies a leading Indian steelmaker with extruded briquettes, which is charging between 3-5% in a high-volume furnace Result: The homogenous blend of iron oxide fines and fine carbon particles have driven a ,
The main used reduction reactors are the blast furnace (BF) and direct reduction reactors (DR) In the blast furnace, iron is reduced and melted and the most common product is liquid iron called hot metal In direct reduction, iron remains in solid state and the product is the so-called direct reduced iron (DRI)
