要約: front page image
(EN) The purpose of the present invention is to manufacture, without the use of iron oxide powder containing metallic iron, such as iron manufacturing dust or mill scale, a carbon composite sintered ore (carbon composite agglomerated ore) with a two-layer structure in which an iron-containing raw material and a carbon material are disposed adjacently and the periphery of a carbon material core is covered with a mixed powder comprising powder of the iron-containing raw material and powder of a CaO-containing raw material. Provided is a sintered ore manufacturing method in which a carbon composite sintered ore is manufactured by sintering, on a pallet of a sintering machine, carbon composite pelletized particles with a two-layer structure in which a carbon material core is covered with a mixed powder containing a powder of an iron-containing raw material and a powder of a CaO-containing raw material, wherein the water content of the carbon composite pelletized particles at the time of pelletization is 8–10 mass% of the total mass of the carbon material core, the mixed powder, and the water content.
