摘要:
본 발명은 제강슬래그를 이용한 소결광 제조방법에 관한 것으로서, 제강슬래그를 급랭 미분화하여 얻어진 슬래그볼(Steel Compound Ball, SCBall)을 석회석 및 니켈슬래그를 일부 대체하는 소결원료로 사용함을 통해, 천연자원의 사용량 감소 및 폐자원으로 취급되는 제강슬래그의 재활용에 매우 유용한 효과를 갖는다.
摘要:
PROBLEM TO BE SOLVED: To provide a method and a device for cooling sintered ores by which members composing the cooling device 10 can be prevented from being deteriorated or broken due to the leaving of the high temperature sintered ores P with respect to the method and a device for cooling sintered ores, by which the stacked sintered ores P during conveyance are cooled by ventilation after sintering. SOLUTION: During the conveyance, the component of the gas, which is allowed to pass through the stacked sintered ores P during the conveyance, in the direction of passing through the stacked sintered ores P during conveyance is made in reverse direction.

摘要:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for feeding sintered ore to a moving trough type cooling machine by which an increase in repair cost can be prevented and, further, the remixing of coarse grains and fine grains separated in the inside of an ore-feed chute for sintered ore can be prevented and a layer of the coarse grains and a layer of the fine grains can be formed as a lower layer and an upper layer, respectively, on a trough. SOLUTION: In the ore-feeding apparatus 1 for feeding the sintered ore to the moving trough type cooling machine, the ore-feed chute 5 for sintered ore is provided below an ore-discharge end 2a of a sintering machine 2, and further, the moving trough type cooling machine 9 is provided below the ore-feed chute 5 for sintered ore. The ore-feed chute 5 extends obliquely with respect to the extending direction of the moving trough type cooling machine 9, and the sintered ore A is fed from the ore-feed chute 5 to the cooling machine 9. The ore-feed chute 5 can form the layer of the coarse grains B as the lower layer on the trough 10 of the cooling machine 9 and also the layer of the fine grains C as the upper layer on the trough 10 by using a partition plate 8 provided to the inside of the chute 5 and extending along the extending direction of the chute 5.
