Abstract

Small coke lumps forming the carbon material core and having a particle diameter of 3-15 mm, iron ore powder forming an outer layer and having a particle diameter of no more than 250 mm, and a CaO-containing raw material are inserted into a pelletizer, then mixed, granulated, coated on the perimeter of the carbon material core to form the outer layer thereon, to create pseudo particles (carbon material-containing granulated particles). A sintering raw material having the carbon material-containing granulated particles mixed with normal granulated particles is inserted onto a pallet in a sintering machine, a charged layer is formed, and a sintered ore (carbon material-containing sintered ore) is produced at a sintering heat for the carbon material contained in the normal granulated particles. As a result, a carbon material-containing sintered ore having an iron-containing raw material and a carbon material arranged in close proximity can be obtained without using a metallic iron-containing iron oxide powder such as iron-production dust or mill scale, and without restricting production volume.
