Title:

A Process for Production of Highly Metallised Low Sulphur Directly Reduced Iron(DRI) In Tunnel Kiln
Value Proposition:

Production of Highly Metallised Low Sulphur Directly Reduced Iron (DRI) in Tunnel Kiln
Summary Application:

Developed product can be used as feed/substitute of scrap material for the electric furnace, BOF furnace and induction furnace for steel making
Advantages:
  • The process utilises ~100% waste raw materials (iron ore fines, slimes and likewise and coal fines such as middling coal, rejected coal, non coking coal, jhama coal and likewise) generated during mining and processing of raw materials for preparation of blast furnace burden.
  • The DRI produced from this process is highly metallised (Metallisation > 96%) with low Sulphur (0.006%S)
  • Used as substitute of scrap /feed material for induction furnace, electric arc furnace and Basic Oxygen Furnace (BOF) for steelmaking.
