Title:

Process for Production of Highly Metallised Directly Reduced Iron Cylinders (DRIC) from Lean Grade Raw Materials

Area:

Material Sciences

Focus Area:

Production of Iron Cylinders

Social Benefits:

The techno-economic of the process have been arrived and found to be favorable (i.e., 2/3rd of the conventional DRI process cost) than the conventional DRI making processes. The electricity consumption during the melting of DRIC in Induction Furnace has been arrived and found to be less (i.e., 25-30%) than the conventional pellet melting.

Brief Description

Description :

The process utilizes ~100% waste/lean grade raw materials to produce value-added products. This invention is useful for converting steel plant and mining waste such as iron ore fines/slime and lean grade coking or non-coking coal (>32% ash) into a highly metallized (metallization >96%) low Sulphur (0.008%S) DRI Cylinders suitable as a feed for induction furnace, electric arc furnace and basic oxygen furnace steelmaking
