Title:
METHOD FOR MANUFACTURING CARBONACEOUS MATERIAL-CONTAINING AGGLOMERATE ORE, AND METHOD FOR MANUFACTURING MOLTEN PIG IRON
Document Type and Number:
WIPO Patent Application WO/2023/171468
Kind Code:
A1
Abstract:
Proposed are a method for manufacturing a carbonaceous material-containing agglomerate ore and a method for manufacturing molten pig iron, with which a highly reducible source material can be obtained and the quantity of reducing material that is used in the manufacture of molten pig iron in a countercurrent moving bed can be reduced. A method for manufacturing a carbonaceous material-containing agglomerate ore according to the present invention includes a step in which carbon-including gas that includes carbon monoxide is brought into contact with a porous material to recover carbon, and an agglomeration step in which a carbon-including source material that includes said carbon is mixed with an iron-including source material and the result is agglomerated.
