Embodiment Construction
[0022] see figure 1 A method for cooling a roll provided in an embodiment of the present invention comprises the following steps:
[0023] Step 1, the roll to be cooled 6 is transported into the cooling cover 2 by the roll transport mechanism 4 , and the cooling cover 2 is fixed on the supporting mechanism 1 .
[0024] In step 2, the nozzles of the U-shaped cooling header 3 in the cooling cover 2 are opened, and the nozzles perform continuous encircling water spray cooling on the surface of the roll to be cooled 6 stacked on the roll transport mechanism 4 .
[0025] Step 3, open the exhaust mechanism 5 on the cooling cover 2, and the exhaust mechanism 5 discharges the water vapor generated when the roll 6 is cooled through the exhaust pipe 2-1 on the cooling cover 2 .
[0026] Step 4, when the temperature of the roll 6 cools down to the required temperature, close the nozzles of the U-shaped cooling header 3 and the exhaust mechanism 5, and stop water spray cooling and air c...
