Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum rod processing cooling equipment, in particular to a rapid cooling device for aluminum rod after processing. BACKGROUND

[0002] Aluminum rod is a kind of aluminum product, and the melting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. After hot working such as rolling and extrusion, the surface temperature of the aluminum rod can reach 300-500 DEG C, and the aluminum rod needs to be cooled by a rapid cooling device before entering the subsequent cutting and straightening processes.

[0003] The existing cooling device for aluminum rod after processing is single water spray cooling, and the cooling time is as long as 1-2 hours, which cannot meet the efficiency requirement of batch production. Some forced air cooling devices have uneven air distribution, slow cooling speed and local temperature difference. When water spray cooling, the temperature difference between the surface and the inside of the aluminum rod is too large, or the local water flow impact is too strong, which can easily cause the aluminum rod to bend and the surface oxidation layer to fall off. If the air flow is concentrated in a certain area during air cooling, it will cause uneven temperature of the cross section of the aluminum rod, and additional straightening is required for subsequent processing, which increases the production cost. Therefore, the cooling effect of the aluminum rod processing cooling device is poor, which affects the physical properties of the aluminum rod, and thus reduces the cooling efficiency of the aluminum rod processing cooling device.
