Description

Technical Field

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

[0002] The roller equipment of the steel mill is responsible for transporting high-temperature slabs. The temperature of the slabs out of the furnace is as high as 1250°C. Therefore, the rollers in contact with them heat up very quickly and must be cooled to ensure the strength of the roller surface and the safe temperature of the bearing seat. If the heat dissipation and cooling cannot be carried out, the steel rolling rollers will deform and bend, resulting in a significant reduction in service life. However, there are still some problems with the existing steel rolling rollers when cooling:

[0003] Poor cooling effect. When cooling the existing steel rolling roller, the traditional cooling method is to cool it by spraying water, and the continuously sprayed cold water cannot evenly contact the outer wall of the roller, which will lead to poor cooling effect of the high-temperature roller.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] A steel rolling roller cooling device, this embodiment is based on the high temperature problem of the steel rolling roller, in order to achieve efficient cooling, such as Figure 1-4 As shown, it comprises a plurality of cylindrical rollers 1 distributed at equal distances, the outer wall axis of both ends of the cylindrical roller 1 is connected with a rotating branch pipe 2, and the outer wall of the rotating branch pipe 2 is rotatably provided with a roller bracket 3, the inside of the cylindrical roller 1 is provided with a circulating cooling component, and the circulating cooling component comprises a first water inlet pipe 7 rotatably plugged into the inner wall of the rotating branch pipe 2, the bottom of the first water inlet pipe 7 is connected to a rectangular pipe 8, and the bottom of the rectangular pipe 8 is connected to a circulating pump 10 through a connecting pipe 9, and the outside of the cylindrical roller 1 is provided with a cooling component;

[0025] By flowing cold water on the inner wall of the cylindrical roller 1, the high-temperature cylindrical roller 1 can be effectively cooled, and the spoilers 17 arranged staggered inside can greatly increase the retention time of the cold water and improve the cooling effect. In order to further improve the cooling effect, the heated hot water is also cooled, thereby achieving continuous and efficient cooling.

[0026] The water inlet pipe of the circulation pump 10 is connected to the water pump 11, and the other end of the water pump 11 is connected to the cooling box 12. The other end of the rotating branch pipe 2 is rotatably connected to the first drain pipe 14, and the first drain pipe 14 is installed on the side of the rectangular water collection shell 5 through a fixing frame. The end of the first drain pipe 14 is located above the cooling box 12, and the inner wall of the cooling box 12 is provided with evaporators 13 distributed at equal distances.

[0027] The cooling assembly includes a rectangular water collecting shell 5 disposed below the roller support 3 , and an inner wall on one side of the rectangular water collecting shell 5 is connected to a second drain pipe 16 , and an inner wall on the other side of the rectangular water collecting shell 5 is connected to a second water inlet pipe 15 .

[0028] The outer wall of the cylindrical roller conveyor 1 is provided with spiral heat dissipation grooves 4, and the inner wall of the cylindrical roller conveyor 1 is staggeredly provided with spoilers 17 distributed at equal distances;

[0029] In order to further improve the cooling effect, continuously flowing cold water is arranged on the outer wall of the cylindrical roller 1, so as to further improve the cooling effect of the cylindrical roller 1, and the spiral heat dissipation grooves 4 on the outer wall of the cylindrical roller 1 can further increase the heat dissipation contact area.

[0030] When this embodiment is used, the cooling device is first assembled. After the assembly is completed, the device is connected to an external power supply, and then cold water is injected into the cooling box 12. After that, the circulation pump 10 is started. The circulation pump 10 will pump out cold water, which will enter the interior of the rectangular pipe 8 through the connecting pipe 9 and the interior of the first water inlet pipe 7 respectively.

The hot water flowing out of the cooled cylindrical roller 1 is discharged from the first drain pipe 14, enters the cooling box 12, and is cooled by the evaporator 13. While the cylindrical roller 1 is cooled, flowing cold water enters the rectangular water collecting shell 5, and the cold water contacts the outer wall of the cylindrical roller 1, which will further cool the high-temperature cylindrical roller 1, greatly improving the cooling effect.
