Our Group boasts of such Steel making facilities which not only encompass the latest technology in metallurgy, but also equipments to ensure quality standards and accuracy. Our Steel Melting Shops include an Electric Arc Furnace of 60 MT capacity per heat and 17 Induction Furnaces, which includes 5 numbers of 20 MT per heat and 12 numbers of 8 MT per heat furnaces. We have capacities to manufacture 1,020,430 MTs of Billets and Blooms, of which 100,000 MTs is in Chhatisgarh, 114,200 MTs in Orissa and 806,230 MTs in West Bengal.

 

 

We manufacture Billets and Blooms at our Steel Melting Shops in Alloy, Carbon and Mild Steel Grades. Our facilities have been designed in a unique integrated manner, in which the Hot Metal from our Blast Furnace is directly poured in the SMS through ladles and overhead cranes. In the furnaces, DRI and Ferro Alloys are added in appropriate mixes to manufacture Liquid Steel. Our Oxygen Plant provides the furnaces with oxygen, required to create an oxidizing atmosphere in them for manufacture of steel.

 

We have also been approved by Research Designs and Standards Organisation (RDSO), Ministry of Railways, for manufacture and supply of Carbon Steel Billets and Blooms for Forging. The minimum and maximum sizes approved for Billets is 100 x 100 mm and 130 x 130 mm respectively, while Bloom size 160 x 160 mm has been approved.

   

The Liquid Steel is collected in ladles using the Eccentric Bottom Tapping method for ensuring absence of slag, and sent to the Ladle Refining Furnace for desulphurization and then to Vacuum Degassing facility for maintaining the Oxygen and Nitrogen contents and removing gaseous elements such as Hydrogen, etc. Next, the Liquid Metal is sent to our Continuous Casting Machines (CCM) for molding them into Billets or Blooms.

With the large scale production of steel at our units and availability of Railway Siding within our plant premises, we are in a position to offer quantities beyond the capacities of our competition in the shortest possible time. We have been awarded the Star Export House Status by the Ministry of Commerce & Industry, Government of India.
