Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a circulating cooling device for a casting and rolling mill. Background Art

[0002] The casting and rolling mill is a new process that directly makes the metal melt into semi-finished billets or finished products. The notable feature of this process is that its crystallizer is two rotating casting and rolling rollers with a water cooling system. The melt completes the two processes of solidification and hot rolling between the rollers. In the production process of aluminum foil, the aluminum liquid needs to be cast and rolled into aluminum plates through the casting and rolling mill. Due to the very high temperatures of the aluminum liquid and aluminum plates, the casting and rolling rollers of the casting and rolling mill are very hot, which affects the normal casting and rolling of the aluminum plates. Therefore, a certain amount of cooling is required to reduce its impact.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN219724534U discloses a cooling device for an aluminum casting rolling mill, including a bottom plate and a cooling trough, the upper end surface of the bottom plate is fixedly connected to fixed rods near the four corners, the upper end surfaces of the four fixed rods are fixedly connected to mounting plates, the upper end surfaces of the mounting plates are fixedly connected to mounting frames on both sides, and the opposite sides of the two mounting frames are rotatably provided with fixed rotating seats and rotating rods at the upper and lower positions respectively, and rollers are fixedly connected between the fixed rotating seats and rotating rods on the same level. In this utility model, the circulating and efficient water cooling effect is set to achieve better cooling of the rollers, so that better physical rapid cooling effect can be achieved to increase the service life of the rollers. At the same time, the multi-layer material set on the rollers can achieve better self-protection of the rollers, and thus can achieve better durability, with better usability and protection.

[0005] However, the above patent still has problems that need to be improved during actual use, the most obvious of which is that the effect of circulating cooling is not ideal and the efficiency of circulating cooling needs to be improved.

[0006] To this end, we proposed a circulating cooling device for a casting and rolling mill to solve the above-mentioned drawbacks. Utility Model Content

A temperature sensor 6 is installed on the inner bottom surface of the water tank 3. When the temperature sensor 6 detects that the water temperature in the water tank 3 exceeds the set value, the driving motor 4 drives the stirring blade 5 to rotate, so as to stir and cool the water in the water tank 3. The generated hot air is discharged from the water tank 3 through the exhaust pipe 8 to achieve cooling of the water. The circulating cooling effect is more ideal, the circulating cooling efficiency is more efficient, the structure is simple, the practicability is strong, and it is worthy of promotion.

[0027] Specifically, the air compressor 13 blows the compressed high-pressure gas out of the air outlet 16 and onto the surfaces of the two rollers 2, so that the rollers 2 can be air-cooled. Compared with a single water-cooling method, the effect is more ideal and the cooling efficiency is more efficient.

[0028] In this embodiment: a control switch 17 is fixedly mounted on the surface of the carrier plate 1 , and the control switch 17 is electrically connected to the drive motor 4 , the air compressor 13 and the temperature sensor 6 through wires.

[0029] Specifically, it is a common circuit connection structure, which will not be described in detail here.

The circulation cooling effect is more ideal, the circulation cooling efficiency is more efficient, the structure is simple, the practicality is strong, and it is worthy of promotion. The air compressor 13 works to blow the compressed high-pressure gas out of the air outlet nozzle 16 and blow it on the surface of the two rollers 2, which can perform air-cooling cooling on the roller 2. Compared with the single water-cooling method, the effect is more ideal and the cooling efficiency is more efficient.
