The ore heating furnace generates a large amount of heat during the whole system operation, and needs to be cooled in time to maintain the stable operation of the ore heating furnace.

[0003] In the related art, the ore heating furnace is cooled by the water cooling mode, and the water cooling is usually composed of a water distributor, a valve, a water collecting tank, a water discharge pipe and a hose, etc. The cooling water is distributed to different equipment by the water distributor, and the temperature abnormality alarm is realized by relying on the temperature measuring element of the water return branch pipe. Although such a system guarantees the cooling function to a certain extent, it still has the following technical defects: the heat load of different areas of the ore heating furnace is significantly different (such as the high-temperature area of the short net system and the relatively low-temperature area of the feeding system). Due to the inconvenience of adjusting the water flow of the water distributor, the cooling water distribution cannot be self-adaptively adjusted according to the change of the heat load, and partial overheating may be caused by insufficient cooling in some areas, while energy waste is caused by excessive water supply in other areas; in addition, the presence of impurities affects the maintenance of the pipeline system when the pipeline system is repaired.
