摘要： Small lump coke having a particle size of 3-15 mm as a carbon material core, iron ore powder having a particle size of not more than 250 µm to be an outer layer and CaO-containing raw material are charged into a pelletizer and mixed and granulated therein to obtain quasi particles formed by coating the carbon material core with the outer layer (carbon material-containing granulated particles). Also, a sintering raw material obtained by mixing the carbon material-containing granulated particles with normal granulated particles is charged onto a pallet of a sintering machine to form a charged layer, and a sintered ore (carbon material-containing sintered ore) is produced by sintering heat of a carbon material included in the normal granulated particles. Thus, the carbon material-containing sintered ore having the iron-containing raw material and the carbon material arranged close to each other is obtained without using metallic iron-containing iron oxide powder such as iron-making dust, mill scale or the like and without restricting production volume.
