Sponge Iron
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

IRON ORE PELLETIZATION PLANT
Iron ore pellets are used in blast furnaces for producing sponge iron steels. Marked by high productivity lower fuel consumption and improved furnace control pellets are now preferred all over the world for primary steel making. Pellets are in the desired range of sizes and possess the desired physical/chemical properties for feeding blast furnace electrical furnace for melting into liquid ...
Direct Reduced Iron and its Production Processes – IspatGuru
· Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction. The coal based process uses any one of the four types of reactors for the reduction reaction. These reactors are (i) rotary kiln, (ii ...
MIDREX® Process
· The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H ₂ and CO content. These gases react with ...
