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
Jun 09 2019 · With the charge of sponge iron and suitable carbon usually more than 15 the energy consumption is reduced to about 5 kWh Reducing the failure rate of the electrode and its wall wear in EAFs The use of sponge iron in comparison with scrap reduces electrode consumption for the following reasons
Since DRI is produced by removing oxygen from iron ore its structure is just like sponge with a network of connecting pores These pores results in a large internal surface area which is about 10000 times greater than the internal surface area of solid iron Due to this DRI is also known as Sponge Iron
Sponge iron can come in lumps or finer particles and is frequently used as an alternative to steel scrap metal The advantages to using this method to create metal parts include elimination of much of the waste of traditional machining the ability to create a wide variety of alloyed components and the ability to heattreat materials for increased strength
Sponge Iron India is the worlds largest producer of sponge iron most of which is produced primarily through the coal based method of production Growth in the sponge iron production can be attributed largely to the popularity of secondary steelmaking route which has shown a phenomenal growth in India
Apr 30 2011 · Sponge iron has many advantages over other similarly smelted iron forms Sponge iron is superior to pig iron as it is richer in iron content Because of this property it has many uses in electric furnaces We can mix sponge iron in its powdered form with many other metals to manufacture a variety of ironcontaining products
However in sponge iron making DRI the SiO2 Al2O3 ratio should preferably be 1 Higher SiO2 in ore causes accretion formation in DRI kiln A balanced Al2O3 content enables easy dislodging of
The process has the advantage of low capital expenditure and no requirement of coking coal The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore 1535 deg C by utilizing carbonaceous material present in the noncoking coal
Advantages of GPIL Pellets Increase the Productivity of the Sponge Iron Less fines generation in the DRI making due to its good physical and metallurgical properties Consistent DRI Blast Furnace Operation Good Air permeability due to its uniformity in size Better Quality of the Sponge Iron Reduce Handling Losses Increase the campaign life of the Kiln
