METHOD FOR IMPROVING REDUCTION DISPERSION INTENSITY OF SINTERED ORE

PURPOSE: A method for improving reduction dispersion intensity of sintered ore is provided to decrease manufacturing cost of sintered ore and increase sintering productivity by permeating a calcium chloride (CaCl2) solution into the already manufactured sintered ore so as to improve reduction dispersion intensity at a low temperature, thereby reducing the injecting amount of subsidiary raw material and coke breeze in the sintered ore manufacturing process. CONSTITUTION: In a method for improving reduction dispersion intensity of sintered ore by adding chemicals to the manufactured sintered ore, the method comprises the steps of providing a storage part (A) in which a calcium chloride solution (10a) is temporarily stored, a mixing part (B) diluting the calcium chloride solution, and a spray part (C) spraying the calcium chloride solution diluted in the mixing part; changing quality of the sintered ore by the calcium chloride solution by spraying a calcium chloride solution diluted in the mixing part to the sintered ore through the spray part, wherein a concentration of the calcium chloride solution supplied to the storage part is 30 to 35%, and the calcium chloride solution transferred to the mixing part from the storage part is diluted, and then sprayed to the sintered ore through the spray part.
