Problems solved by technology

Only using high-pressure water cooling method, the cooling effect is not good if the water pressure is small, and the high power of the equipment is required if the water pressure is high; the current commonly used air mist cooling method, the amount of sprayed water is less than the water sprayed by the water-air method, cooling low ability

Embodiment Construction

[0020] figure 1 , figure 2 and image 3 In , the on-site installation arrangement of the roll water-air cooling nozzle assembly 4 is illustrated. The roll water-air cooling nozzle assembly 4 is installed and fixed on the support bottom plate 2 through the connecting piece 6 . During on-site installation and arrangement, the exit direction of the water-air nozzle 20 on the roll water-air cooling nozzle assembly 4 faces the high-temperature cooling area of ​​the roll 1 . According to the actual size of the high-temperature cooling area of ​​the roll 1 on site, different numbers of roll water-air cooling nozzle assemblies 4 can be configured.

[0021] From Figure 4 It can be seen from the figure that the roll water-air cooling nozzle assembly 4 includes a valve body 7 , an air inlet pipe 9 , a water inlet pipe 15 , and a water-air nozzle 20 . The compressed air pipeline 3 is connected with the intake pipe 9, and the compressed air is input to the valve body 7, and the comp...

Abstract

The invention discloses a water-gas cooling spraying nozzle assembly for a roller. The water-gas cooling spraying nozzle assembly comprises a valve body, an air inlet and a water inlet are formed in the valve body, an air inlet pipe is installed in the air inlet, and a water inlet pipe is installed in the water inlet; the air inlet pipe is communicated with a water-air mixing channel through an air inlet channel and an air inlet shrinking channel, and the water inlet pipe is communicated with the water-air mixing channel through a water inlet channel and a water inlet guide channel; and a water-air outlet is formed in the tail end of the water-air mixing channel, and a water-air spraying nozzle is arranged on the water-air outlet. According to the water-gas cooling spraying nozzle assembly for the roller, water vapor on the surface of a rolling groove of the roller can be blown away through compressed air, circulation of water and air on the surface of the rolling groove of the roller is improved, the cooling efficiency of the roller is improved, and the service life of the roller is prolonged; the requirement of the spraying nozzle assembly for the cooling water pressure is not high; and due to the fact that the pressure of the compressed air is larger than that of cooling water, the pressure of the cooling water of locality in the water-air mixing channel can be increased by adjusting the pressure of the compressed air, and the cooling effect is improved.

Description

technical field [0001] The invention relates to a roll water-air cooling nozzle assembly and belongs to the technical field of steel rolling technology. Background technique [0002] In the process of hot rolling steel, the rolling groove and the rolling piece will generate a lot of heat due to the contact friction, and the surface temperature of the rolling groove will rise sharply. ACCIDENT. The temperature in the rolling groove area is high, steel sticking is easy to occur, and it is difficult to remove the finished rolled piece from the groove, resulting in a decline in the yield. [0003] In traditional cooling methods, high-pressure water is used for cooling or vapor-mist cooling. Only using high-pressure water cooling method, the cooling effect is not good if the water pressure is small, and the high power of the equipment is required if the water pressure is high; the current commonly used air mist cooling method, the amount of water sprayed is less than that of th...
