Abstract

PURPOSE: To manufacture sintered ore of superior quality without hindering the gas permeability of starting materials by adding minus mesh return ore of sintered ore sieved immediately before feeding to a blast furnace to blended starting materials for sintering and by feeding the starting materials to a sintering machine.
CONSTITUTION: Minus mesh 1 having 2W5mm size separated from sintered ore sieved before charging into a blast furnace is stored in a hopper 17 once. Blended starting materials such as fine ore having ≤1mm size produced in a process for crushing sintered ore, fine iron ore, coke breeze and limestone are charged from hoppers 3 in a fixed ratio, passed through a primary mixer 5 and a secondary mixer 6, carried with a belt conveyor 16, and put in an ore feeding hopper 7. At this time, the minus mesh 1 stored in the hopper 17 is added to the blended starting materials on the conveyor 16 by 5W10%. The mixed materials are fed to a sintering machine 9. Thus, the gas permeability of the starting materials for sintering is not hindered, and sintered ore of superior quality is manufactured stably.
