AI Technical Summary
During the roll collection process of the boutique five-line workshop, the temperature of the roll collection barrel increases, causing the plate strips to stick to the barrel wall, causing scratches. The existing fans have poor cooling effect and are difficult to effectively solve the problem of high-temperature steel sticking.
Using nitrogen and water to mix, high-pressure water spray on the double-layer rolling barrel wall quickly takes away heat, reduces the temperature, and prevents water mist from scattering through the outer barrel wall.
High-pressure water jet can quickly and effectively reduce the temperature of the coil-coil barrel, from 460℃ to 240℃, maintain a low temperature state, and avoid the occurrence of high-temperature steel sticking.

Technical Field
[0001] The utility model relates to a system for cooling a coiling drum, belonging to the technical field of metallurgical auxiliary devices. Background Art
[0002] During the production process in the fine wire workshop of the wire rod factory, the fine steel products have high requirements for surface scratches. During the coiling process, continuous production for a long time will cause the temperature of the coiling drum to rise. When the temperature reaches above 400 °C, when the wire rod falls into the drum, it will adhere to the drum wall, resulting in surface scratches on the wire rod.
[0003] The existing method is to place a fan beside the coiling drum and use the fan to cool the coiling drum during production. During the long production process, the cooling effect is not good. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a system for cooling a coiling drum. By mixing nitrogen and water to generate high-pressure water and spraying it on the wall of the double-layer coiling drum, the high-pressure water can quickly and effectively take away the heat of the coiling drum wall, reduce the temperature of the coiling drum, and maintain a low-temperature state to ensure that there is no high-temperature steel sticking situation, solving the above problems in the background art.

The drum wall is a double-layer structure, comprising an inner drum wall and an outer drum wall. The water pipe and the nitrogen pipe are connected to the gas-water mixing pipeline, and the gas-water mixing pipeline is connected to the pipeline nozzle. The pipeline nozzle is installed between the inner drum wall and the outer drum wall, and the water spraying direction is towards the inner drum wall.
[0006] The number of the pipeline nozzles is more than one, and they are evenly arranged between the inner drum wall and the outer drum wall.
[0007] Control valves are provided on the water pipe and the nitrogen pipe, and they are opened simultaneously during use.
[0008] The beneficial effect of the utility model is: by mixing nitrogen and water to generate high-pressure water and spraying it on the wall of the double-layer coiling drum, the high-pressure water can quickly and effectively take away the heat of the coiling drum wall, reduce the temperature of the coiling drum, and maintain a low-temperature state to ensure that there is no high-temperature steel sticking situation.

[0012] In order to make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a small part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0013] A system for cooling a coiling barrel, comprising a water pipe 1, a nitrogen pipe 2, an air-water mixing pipeline 3, a drum wall and a pipeline nozzle 6. The drum wall is a double-layer structure, comprising an inner cylinder wall 4 and an outer cylinder wall 5. The water pipe 1 and the nitrogen pipe 2 are connected to the air-water mixing pipeline 3, and the air-water mixing pipeline 3 is connected to the pipeline nozzle 6. The pipeline nozzle 6 is installed between the inner cylinder wall 4 and the outer cylinder wall 5, and the water spraying direction is towards the inner cylinder wall 4.
[0014] The number of the pipeline nozzles 6 is more than one, and they are evenly arranged between the inner cylinder wall 4 and the outer cylinder wall 5.
[0015] Control valves are provided on the water pipe 1 and the nitrogen pipe 2, and they are opened simultaneously during use.
[0016] In the production process of the coil, the wire rod is transported by the SM roller path 7 to the coiling barrel 8 for collection into a coil. After each collection, it descends to the coiling core rod 9 to complete one collection. In actual application, first weld the drum wall of the coiling barrel into a double layer, comprising an inner cylinder wall 4 and an outer cylinder wall 5, then install the pipeline nozzle 6, make the pipeline, and the water pipe 1 and the nitrogen pipe 2 are respectively filled with water and nitrogen, and are mixed in the air-water mixing pipeline 3. During production, the nitrogen pipe and the water pipe are opened simultaneously to generate high-pressure water, which is sprayed onto the surface of the inner cylinder wall 4 by the pipeline nozzle 6 to achieve cooling. The high-pressure water can quickly and effectively take away the heat of the coiling barrel wall and reduce the temperature of the coiling barrel. To prevent the water mist from scattering and affecting the performance of the wire rod, the outer cylinder wall 5 is set to ensure the cooling of the inner cylinder wall by the water mist.
[0017] Through actual verification, after adopting the present utility model, during the long-term production process, the temperature of the coiling barrel can be reduced from 460 °C to 240 °C and maintain a low temperature state, ensuring that the situation of high-temperature sticking of steel does not occur.
