Description

Technical Field

[0001] The utility model relates to the technical field of strip steel cold rolling, in particular to a strip steel cold rolling device. Background Art

[0002] At present, a Chinese patent with announcement number CN220259085U discloses a strip cold rolling machine, which is provided with a drain pipe for spraying water on the surface of the cold rolling roller to cool the surface of the cold rolling roller. However, in actual use, the spray path of the drain pipe passes through the strip material, that is, when the drain pipe cools the cold rolling roller, the drain pipe will also spray the strip material. In the process of cold rolling of the strip, the strip material needs to be cold rolled by multiple cold rolling rollers to complete the cold rolling process. This phenomenon will cool the strip material prematurely, which is not conducive to the subsequent cold rolling work. Utility Model Content

[0013] 2. The two sprinkler heads are each equipped with a water supply system, which can make the cooling schemes between the cold rolling rollers independent of each other.

[0014] 3. The water spray panel is designed to be arc-shaped, so that the water spray panel can cool down the surface of the cold rolling roller, and can cover a wider cooling area under the same volume.

[0015] 4. The water-absorbing roller can further dry the surface of the cold rolling roller. When water droplets cannot be evaporated by high temperature in time, the water-absorbing roller can be used to absorb water to prevent the water droplets from contacting the strip.

[0016] 5. The rotation setting of the water absorption roller can reduce the friction between the water absorption layer and the cold rolling roller and extend the service life of the water absorption layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-4, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 4 As shown, the utility model discloses a strip cold rolling device, including a cold rolling frame 1, the cold rolling frame 1 is provided with two cold rolling rollers 2 which rotate up and down, and at the same time, the cold rolling frame 1 is also provided with two water spray heads which rotate up and down, in this structure, the two cold rolling rollers 2 are located between the two water spray heads, and a water spray panel 31 is provided at one end of the water spray head facing the cold rolling rollers 2, the water spray panel 31 is an arc-shaped plate, and a spray hole 311 is opened on the water spray panel 31, in addition, each water spray head is equipped with a group of water supply mechanisms, the water supply mechanism includes a water tank 4 and a high-pressure water gun 5, the high-pressure water gun 5 is used to pump water from the water tank 4 and deliver water to the water spray head, so that water can be sprayed out from the spray hole 311 under high pressure.

[0026] The working principle of the above structure is as follows: first, since the water spray panel 31 is located on the side opposite to each other of the two cold rolling rollers 2, when the water is sprayed out from the spray hole 311, the water can be sprayed onto the surface of the cold rolling roller 2 for cooling, and can also be blocked by the cold rolling roller 2 to prevent the water from contacting the surface of the strip. Secondly, since the surface temperature of the cold rolling roller 2 is very high, the water will continue to evaporate after being sprayed onto the surface of the cold rolling roller 2. Therefore, it is only necessary to adjust the size of the spray hole 311 and the frequency of the intermittent water spraying of the high-pressure water gun 5 to allow the water on the cold rolling roller 2 to be evaporated before it contacts the strip.

[0027] In order to further ensure that water does not contact the steel strip, a roller surface drying mechanism is provided on the cold rolling stand 1 .

[0028] The roller surface drying mechanism specifically includes a water-absorbing roller 6. In this structure, each cold rolling roller 2 is equipped with two water-absorbing rollers 6, and the water-absorbing rollers 6 are respectively located on both sides of the water spray head. In addition, the water-absorbing layer 7 is provided on the outer cover of the water-absorbing roller 6. The water-absorbing layer 7 is in contact with the roller surface of the cold rolling roller 2. When the cold rolling roller 2 just starts to work and its surface temperature is not enough to completely evaporate the water, the water-absorbing layer 7 can be used to absorb the water droplets on the cold rolling roller 2. At the same time, in order to further reduce the friction between the water-absorbing layer 7 and the cold rolling roller 2, the water-absorbing roller 6 is rotatably arranged on the cold rolling frame 1.

[0029] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
