Manufacturing Unit
Sinter Plant
Sinter Plant (SINTER): A 33 M2 sinter plant, designed by Beijing Sino-Steel Industry & Trade Group Corp.(SSIT) and Jiangsu Province Metallurgical Designing Institute (JSMDI) Co. Ltd. The technology is based on principle of economical, applicable safe and operational. The annual production is 3,64,000 Tonnes.
Mini Blast Furnace (MBF)
Mini Blast Furnace (MBF): A Blast furnace of working volume 350 M3 designed by MECON Ltd. to produce 3,00,000 MT/annum of basic grade hot metal has been installed and successfully commissioned. The hot metal is mainly used in the steel melting shop as a raw material and surplus hot metal poured in pig casting machine. The Pig casting machine is designed by KBS Paramount & capacity 800 Tonnes per day (TPD).
The Blast furnace gas is used for stoves heating, heating of preheating furnace of bar and section mill, heating of boiler ,sinter plant. Slag which is a byproduct is mainly sold to cement plants.
- Capacity 800 Tonnes per day
- Volume 350 M3 designed by MECON Ltd.
- 3,00,000 MT/annum of basic
Direct Reduction Plants
Direct Reduction Plants (DRP): Based on Krupp’s Codir process. The DRPs can produce 2,62,000 tones per year of Sponge iron from iron ore and coal. Additionally, the flue gases help generate 30 MW of Electric power.
Power Plant
Power Plant (PP): A 30 MW Captive Power Plant is having two turbine set and two boilers. One boiler operates on the flue Gas from the Sponge Iron Plant (Direct Reduction Plant) and the other uses fine coal with fluidized Bed process.
