PCT No. PCT/KR96/00251 Sec. 371 Date Aug. 28, 1997 Sec. 102(e) Date Aug. 28, 1997 PCT Filed Dec. 27, 1996 PCT Pub. No. WO97/24414 PCT Pub. Date Jul. 10, 1997A method for manufacturing coal agglomerates for use in a direct smelting reducing furnace is disclosed, in which a fine coal is agglomerated at a high temperature in a simple manner, or anthracite or low free swelling coal having a low free swelling index is mixed with the fine coal, and the mixture is agglomerated at a high temperature, thereby turning the low quality coal to useful purpose. The present invention is characterized in that a fine coal having a free swelling index of 3.0 or more and a particle size of 8 mm or less, or the fine coal mixed with 70 weight % of anthracite or a low free swelling coal, is maintained at 600 DEG C. or over for 5 minutes or more, thereby manufacturing coal agglomerates for use in a direct smelting reducing furnace. |
