  • Mini Blast Furnace : SPL has Tata Korf MBF with a capacity of 2,75,000 TPA liquid metal equipped with Hot Blast Stoves and Sinter plant. In the manufacturing process of MBF, generation of slag which is around 30 to 35% is utilized for producing slag cement in the Mini Cement Plant and the surplus slag is sold in the market.
    MBF has a 2.5 MW Captive Power Plant, which is run through its own BF gas and the present generation of power is 1.7 MW.
  • Sinter Plant : SPL has set up a 33 Sq.Mtrs. Sinter plant, having a rated capacity of 1400 MT / Day, with an objective to consume iron ore fines in place of costlier calibrated ore.
  • Mini Cement Plant : A mini Cement Plant was set up in 1995 in order to utilize the slag being generated from MBF. The capacity of Cement Plant is 1,00,000 TPA and is categorized as Mini Cement Plant as per central excise tariff. Slag cement produced in the cement plant is sold under the Brand “Srikalahasthi Gold” Cement. Around 15% of the production is utilized internally for cement mortar lining of DI Pipes in the DI Pipe plant and balance quantity of slag cement (PSC) is sold in Chennai/AP/Kerala markets.

    The Cement plant has 2 Nos. Vertical Shaft Kilns of capacity 100 TPD and 60 TPD with a cement mill. Major raw material used in the Cement manufacturing is limestone, which is sourced from leased limestone mines of the Company situated at Kadapa Dist. in Andhra Pradesh. By-products namely coke fines and iron ore fines also are utilized in the cement plant.
  • Ductile Iron Pipe Plant :The core business of SPL is manufacture and supply of DI Pipes. All other infrastructure mentioned above are backward/supportive integration for manufacturing DI Pipes. The capacity of DI pipe plant is 2,25,000 TPA. Liquid metal from MBF is the major raw material and power generation from 12 MW CPP is mainly utilized in DI Plant. An additional Annealing Furnace was installed in 2009, which is designed for using BF gas and thus oil (HSD/LDO) consumption is reduced significantly. There is flange pipe unit, which produces Flange pipes, as per market requirement.

    Profile of the plant:- Induction Furnaces – 6 Nos., Converters – 2 Nos., Spinning Machines – 8 nos., Annealing Furnaces – 2 Nos., & Finishing Lines 5.
