SEML was one of the first companies to install a sponge iron plant in the Siltara, Raipur area. Sponge Iron or Direct Reduced Iron is produced by reducing Iron Ore (in the form of lumps/pellets) using non-coking coal in a rotary kiln. The coal acts as the fuel as well as a reducing agent & Oxygen is removed from the Ore to produce Sponge Iron. Since the reduction takes place in the solid phase only it is called Direct Reduction. The finished product has pores like a sponge due to removal of Oxygen, thus it is also known as Sponge Iron. The hot flue gases produced in the reactor during the process are used in Waste Heat Recovery Boilers to produce Steam. This helps us in economizing our power generation costs.
Billets are semi-finished steel products with a square cross section usually up to 160mm x 160mm. This product is either rolled or continuously cast and is then transformed by rolling to obtain finished products like wire rod, merchant bars and other sections. At SEML, billets are produced using continuous casting process. The molten steel is continuously cast via a tundish into a water-cooled copper mold causing a thin shell to solidify. This ‘strand’ is then withdrawn through a set of guiding rolls and further cooled by spraying with a fine water mist. The solidified shell continues to thicken until the strand is fully solidified. Finally, the strand is cut into desired lengths and these are either discharged to a storage area or to the hot rolling mill. Our annual billet production capacity is 200,000 MT.
