To provide a rotary circular cooling apparatus capable of improving the cooling capability of a sintered ore while saving power consumption without inviting deterioration in the quality of the sintered ore, and to provide a method for cooling the sintered ore using the cooling apparatus.
The rotary circular cooling apparatus 10 includes: an annular cooling tank 12 composed of an outer peripheral sidewall 14 and an inner peripheral sidewall 15 provided on the upper surface of a rotary table 13; and a cooling water supply means 25 including a cooling air introduction port 18 provided at the lower part of the inner peripheral sidewall 15 and a cut-out device 23 for cutting out cooled sintered ore 11 from a gap 16 between the outer peripheral sidewall 14 and the rotary table 13 for cooling water 27 supplied from a plurality of upper positions of the annular cooling tank 12 to the inner surface 26 side of the inner peripheral sidewall 15. In the method for cooling the sintered ore, the cooling water 27 supplied to the inner surface 26 side of the inner peripheral sidewall 15 by the cooling water supply means 25 is made to flow down along the inner peripheral sidewall 15 to cool the upper part of the inner surface 26 of the inner peripheral sidewall 15, and the cooling water 27 having flowed down to the cooling air introduction port 18 is scattered into the cooled sintered ore 11 stored in the cooling tank 12 by cooling air.
