Brief Description
Description : | The process utilizes mill scale and lean grade non-coking coal for the production of highly metalized DRI through Tunnel Kiln. This invention is useful for converting mill scale generated in the primary and secondary sectors of the iron and steel industries into highly metalized DRI. Lean grade non-coking coal left in the mines head is utilized as a reductant for the conversion of mill scale into DRI. DRI produced from this process has a very high degree of metallization (Metallisation >92%) and is suitable as a feed for induction furnace, electric arc furnace and basic oxygen furnace for steel making. |
