Implementing Organization
National Metallurgical Laboratory (NML)
About
Developed product can be used as feed/substitute of scrap material for the electric furnace, BOF furnace and induction furnace for steel making.
Outcome / Output
The process utilises ~100% waste materials to yield a value added product, This invention is useful for converting steel plant wastes fines / mining waste fines such as iron ore slime/fines, middling and rejected coal containing more than 25 % ash into a highly metallised (Metallisation 96%) low Sulphur (0.006%S) DRI suitable for induction furnace, electric arc furnace and blast furnace for iron and steel making.
