How do you make iron iron sponge?
Sponge iron making is the process of removing oxygen from the ore under controlled parameters. This is done in a rotary kiln followed by a rotary cooler. The process is most suitable for Indian raw material of high-grade iron ore and non-coking coal.
What is difference between iron ore and sponge iron?
Iron is extracted from its ore through removal of oxygen, which is a process called its reduction. Another process is through blast furnace where the ore is heated with carbon (coke). Iron thus produced using coke in blast furnaces is called pig iron, while iron produced through direct reduction is called sponge iron.
What is the price of sponge iron?

Why is DRI called sponge iron?
It is Coal Fuel based DRI. Coal based Sponge-iron is a metallic product produced through direct reduction of iron ore in the solid state . After reduction of iron ore pellet the product resembles sponge because of pores left behind after removal of oxygen. As such it is called Sponge Iron.
What is sponge iron Class 10?
Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore.
Is DRI pig iron?
Direct Reduced Iron (DRI) is the second most viable source of virgin iron used in steelmaking after pig iron or hot metal produced in blast furnaces. DRI is produced by direct reduction of iron ore using carbon monoxide and hydrogen.
Which is better sponge iron or pig iron?
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 iron-containing products. For instance, we can produce wrought iron from sponge iron.
What is Fe m in sponge iron?
This porous structure gives DRI an appearance of a sponge and because of it, DRI is also known as sponge iron. Iron content in the DRI is in two forms. One is in metallic form which is known as metallic iron, Fe (M), and the second form is iron present in residual iron oxides, Fe (O).
What is the rate of iron per kg in India?
Price Range : Rs 51-55/Kilogram.
What is 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.
How is sponge iron?
Sponge iron is formed through the reduction of iron ore to metallic iron through reaction with carbon in the form of coal, etc. at approx. 1100 degree Celsius. Sponge iron is also referred to as direct reduced iron, metalized iron, or hot briquetted iron.
What is spongy iron?
Sponge iron is a spongy mass of iron which is a metallic product produced through direct reduction of iron ore/ iron pellet in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore or pellets.
What is the chemical name of sponge iron?
3.3.3.1 Direct Reduced 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.
How to convert iron ore to sponge iron?
In the first step, iron ore is reduced to sponge iron in a shaft furnace by means of reducing gas. In the second step, the reduced iron is completely reduced and melted in the melter-gasifier vessel.
What is sponge iron used for in the steel industry?
Sponge iron is used in the iron and steel industry as a substitute for scrap in induction and electrical arc furnaces. Over the years, the shortage of expensive melting scrap has made sponge iron a significant raw material for manufacturing high quality steel.
