The first step of Billet production is of procurement of sponge iron. Best quality sponge iron is procured from our Kilns and sister industries. This sponge iron is later fed to the furnace by a giant crane. The induction furnace at a high temperature melts the sponge iron. The plant has two induction furnaces of high capacities. The furnaces are run by a power station, which is controlled, via computerized systems. Inductotherm India Ltd., the best in the industry, manufactures these systems.
After the quality of the molten iron is insured, the furnace tilts and pours it into a ladle maneuvered by a crane. The crane moves this ladle towards the caster and pours the molten iron into it. The caster then casts the molten iron into Continuous Casts. These casts are cooled with the help of water and air pressure and form the billets of required size.
As the billets pass towards the cooling bed, they are accurately cut into the required size by a team of expert foremen. Finally, the hot billets are laid on the cooling bed, where they cool down and get ready for being transported.
