Embodiment 1

[0027] figure 1 with figure 2 The atomization cooling equipment shown mainly includes a door frame 1 with a cover, a bellows 2, a fan 2-2, a water tank 3, an ultrasonic atomizer 3-1, an atomization nozzle 3-2, a temperature sensor, and a door curtain 7 , Control box 8. The two facing side frames of the portal frame 1 are double-layer and multi-span structures formed by welding angle steel. They are all packaged with aluminum skins to form the outer cover 1-4 and the inner cover 1-5. All the aluminum skins are riveted with aluminum rivets and the angle steel frame. The two sides, the top slope and the exhaust channel 1-2 aluminum skins form an integrated smooth surface. Streamlined airflow guide surface, the inner top surface of the door frame 1 is a conical exhaust guide plate 1-1, the conical exhaust guide plate 1-1 gradually gathers upwards to form a constriction, and the constriction extends vertically upwards to the air exhaust outlet 1 -3 forms the exhaust passage 1-2...

Abstract

The invention discloses a method for cooling an aluminum coil through ultrasonic water vapor atomization and relates to the technical field of high-temperature material cooling in the metal machining industry. The method includes the steps that the annealed high-temperature aluminum coil is placed in an atomizing cooling device, the temperature of the aluminum coil is measured, and when the temperature of the aluminum coil is higher than 300 DEG C, rotating ascending airflow generated on the lower portion of the atomization cooling device performs air cooling on the aluminum coil; when the temperature of the aluminum coil ranges from 150 DEG C to 300 DEG C, the air volume is kept, meanwhile, an ultrasonic atomization device is started, and fog with atomization particles being 1-5 microns is generated; and when the temperature of the aluminum coil is lower than 150 DEG C and higher than 130 DEG C, the air volume is controlled to range from 3000 m<3> / h to 12000 m<3> / h, and meanwhile, the ultrasonic atomization device is started intermittently; and when the temperature of the aluminum coil is lower than a T value, atomization is stopped, the air volume is kept to be controlled between 10000 m<3> / h to 24000 m<3> / h till the aluminum coil is cooled to room temperature or required temperature. The method solves the problems that an existing large-coiling-diameter aluminum coil is low in cooling efficiency and long in cooling time.

Description

technical field [0001] The invention relates to the technical field of cooling high-temperature materials in the metal processing industry, in particular to a process method for atomizing and cooling large-tonnage aluminum coils. Background technique [0002] After rolling and annealing, the temperature of aluminum coils is high, especially for large-diameter aluminum coils, it takes a long time to cool down to the allowable temperature of the next process, which makes the cooling speed of aluminum coils one of the reasons restricting the rapid production of factories. The existing aluminum coil cooling method is: adopt multiple 1.5kw axial flow fans to blow air directly against the aluminum coil for cooling. This cooling method has the following disadvantages: 1. The efficiency is low, and the cooling time is as long as 12 to 24 hours, or even longer; 2. The cooling of the aluminum coil is uneven, resulting in uneven distribution of the components of the aluminum coil. Co...
