● Sponge Iron gets its name from its unique physical characteristics. It has hole marks on its surface.
● These hole marks emerge during the ‘natural reduction’ process where iron ore is warmed with carbon.
● The commercial name for this process is called Direct-Reduced Iron (DRI)
● Iron Ore and coal are the raw materials used in the DRI process.
● This method is adopted because it solves a lot of problems that were faced when using the traditional blast furnace method. The DRI process is also preferred since it uses less energy.
Sponge Iron – How Is It Made?
So we will quickly explain what is involved in the DRI process.
● First, iron ore lumps are placed with iron-coking coal in a kiln.
● Next, they are combusted in the presence of oxygen for 12 hours.
● Post which the products are air-cooled. The result is Sponge Iron as pellets that are initially stuck together but are later magnetically separated.
● Each sponge iron is screened based on size and then prepared for dispatch.
Sponge Iron – Where Is It Used?
Sponge Iron plant manufacturers in India use sponge iron as a substitute for scrap in induction and electrical furnaces. The reason for this is that melting scrap is expensive and also in short supply, so sponge iron is the perfect alternative when it comes to using it in the production of high-quality steel.
India is considered to be the second-largest manufacturer of sponge iron globally. This is due to the large production capacity of Sponge Iron Plant Manufacturers and the abundance of Iron Ore deposits in the country.
