| Billets are semi-finished steel products with a square cross section usually up to 160 mm x 160 mm. This product is continuously cast and is then transformed by rolling in rolling mill to obtain finished products like Wire Rod, Ribbed Coil, 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 This “strand” is then withdrawn through a set of guiding rolls and further cooled by spraying with a fine water mist.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 send to the rolling mill directly for hot rolling. Our annual billet production capacity is 3,20,000 MT.
