发明名称 METHOD FOR PRODUCING SINTERED ORE AND SINTERING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a method for sintered-ore production in which high-quality sintered ore having high strength can be safely produced in a high yield with a sintering apparatus of a downward suction type, and the sintering apparatus. Ž<P>SOLUTION: The method for sintered-ore production comprises: placing a raw material to be sintered comprising fine ore and a carbon material on a circulating pallet 8 to form a raw-material layer 9; igniting the carbon material of the raw-material layer in an ignition furnace; and sucking air with a wind box disposed under the pallet to thereby produce sintered ore. After the raw-material layer 9 has been ignited in the ignition furnace, a liquid fuel is atomized to a particle size of 100 μm or smaller and supplied to over the raw-material layer 9, and the atomized liquid fuel is supplied from over the raw-material layer 9 into the raw-material layer 9 after having been diluted at least to the lower limit of ordinary-temperature combustion concentrations.
