It is mainly used to process aluminum ingots or aluminum plates into required thin plates or strip materials through rolling process. Aluminum casting and rolling mill is usually composed of a series of roller mills. Each roller mill has different functions, including rough rolling, finishing rolling and shaping. During the rolling process, the rollers need to be continuously cooled to avoid affecting the performance of the material.

The cooling device is provided with a reflux box, a connecting pipe, a water pump, a water pump and a water spray pipe. When the device is used to cool the rolls at high temperature, the tap water sprayed from the mist nozzle continuously sprays the rolls to cool them down, and then the sprayed tap water naturally falls into the reflux box, and the refluxed tap water is extracted by the water pump and then sent back to the mist nozzle through the water spray pipe for spraying. In this way, when used in combination, only the tap water splashed outward during the cooling process needs to be replenished, and the whole process completes the recycling of water resources, so that the device can avoid the problem of long cooling time of the rolls and a large amount of tap water wasted during the cooling process, thereby achieving the purpose of energy saving and improving the efficiency of the device for roll cooling.
