Product Description

Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, 500 TPD)

Solid state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI). Since DRI is produced by removing oxygen from iron ore, its structure is just like sponge with a network of connecting pores. These pores results in a large internal surface area which is about 10,000 times greater than the internal surface area of solid iron. Due to this, DRI is also known as Sponge Iron.

Sponge Iron is gaining more popularity because of the following reasons…

  • Scrap is getting scarcer by the day
  • Quality and composition variations are compelling
  • Tramp elements coupled with Sulphur and Phosphorus hamper the end product quality of sale-able steel
  • Uniform known composition, size and high bulk density compared to scrap
  • Low Capex and gestation period compared to Gas based DRI plant
  • It can be produced with non-coking coal and poor quality of coal that is available in abundance
  • Capability of forming protective layer of foamy slag in the bath
  • Potential of sensible heat recovery from waste gases
  • Maintenance of Sulphur level in steel by its removal during Sponge iron production**
  • Lower refining requirements of steel produced
  • It allows steelmaking to dilute metallic residuals in scrap
