Title:
SINTERING APPARATUS AND METHOD FOR MANUFACTURING SINTERED ORE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/021634
Kind Code:
A1
Abstract:
A sintering apparatus according to the present invention comprises: a sintering carriage capable of charging a raw material for sintering and capable of moving in a proceeding direction of a sintering process; an ignition furnace installed to inject a flame into a charged raw material layer within the sintering carriage on a path where the sintering carriage moves in the proceeding direction of the sintering process; and a plurality of wind boxes installed on the lower side of the ignition furnace and installed side-by-side so as to reduce an area of a suction passage from the ignition furnace toward a sintering end point. Therefore, an embodiment of the present invention can suppress or reduce the generation of unreacted sintered ores in an upper layer portion and the occurrence of over-firing sintered ores in a lower layer portion, by regulating a flow rate of air through the plurality of wind boxes and further supplying a heat source to the upper layer portion by using a reflecting member. Further, sintered ores having uniform quality can be obtained regardless of the upper layer portion, an intermediate layer portion, and the lower layer portion, or for the entire raw material layer.
