Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of annular coolers, and in particular, to annular coolers. Background Art

[0002] Currently, ring coolers are widely used in the metallurgical industry to cool finished sinter during sintering production. During the cooling process, the cooling fan in the ring cooler converts a large amount of heat from the finished sinter into hot air. During this process, the surface temperature of the ring cooler's guardrails rises to around 350°C.
