Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron and steel metallurgy technology, and in particular to a special air-cooling device for steelmaking plants. Background Technology
[0002] Beiying Steel Plant uses a slow cooling method to cool molten steel samples during the production of high-carbon steel. This prevents cracks and segregation caused by rapid cooling during the process, which could lead to inaccurate sample composition analysis and production difficulties. However, the slow cooling method results in a long cooling time, significantly impacting production rhythm. Therefore, by modifying the compressed air pipeline to use a phased cooling method, the cooling time of the samples is greatly shortened, meeting the demands of a fast-paced production model.
[0003] Air cooling is a type of cooling method that uses air as a medium to cool the object that needs to be cooled. This typically involves increasing the surface area of the object, increasing the rate at which air flows over it per unit time, or a combination of both. The former can be achieved by adding heat sinks to the object's surface; these are usually hung on the outside of the object or fixed to it for more efficient heat dissipation. The latter uses fans (ventilators) to enhance ventilation and improve cooling. In most cases, adding heat sinks can significantly improve cooling efficiency.
[0004] Traditional air-cooling equipment cools molten steel samples slowly, with an average cycle of 5.4 minutes, which is too long and cannot achieve complete cooling, potentially injuring operators.
[0005] Secondly, the existing compressed air pipelines used for air cooling lack supporting and reinforcing structures at their assembly locations, resulting in insufficient stability during use, causing vibration, noise, and affecting usability. Therefore, a new structure is urgently needed. Utility Model Content
[0006] To address the aforementioned technical problems, a special air-cooling device for steelmaking plants is provided. The technical means employed in this invention are as follows:
[0007] A special air-cooled equipment for steelmaking plants includes: an air-cooled equipment workbench, a sample delivery and placement air-cooled box, a compressed air pipeline, an air steel pipe, and a supporting and reinforcing structure. The top side of the air-cooled equipment workbench is connected to an equipment connection back plate. The sample delivery and placement air-cooled box is placed on the top of the air-cooled equipment workbench. A compressed air pipeline is provided on one side of the sample delivery and placement air-cooled box. An air steel pipe is connected to the compressed air pipeline. One end of the air steel pipe passes through the front side of the sample delivery and placement air-cooled box. A ball valve is connected to the connection between the compressed air pipeline and the air steel pipe.
[0008] One side of the support and reinforcement structure is installed on the equipment connection back plate, and the other side is connected to the compressed air pipeline for clamping the compressed air pipeline.
[0009] Furthermore, the support and reinforcement structure includes a shock-absorbing assembly structure group, a connecting rod, and a mounting frame. The mounting frame is installed on the equipment connection back plate. One end of the connecting rod is connected to the mounting frame, and the other end is connected to the shock-absorbing assembly structure group. The shock-absorbing assembly structure group is provided with a clamping structure for clamping compressed air pipes.
[0010] Furthermore, the mounting bracket is connected to one side of the equipment connection backplate by fixing bolts.
[0011] Furthermore, the front surface and inner side of the shock-absorbing assembly are both connected to a first shock-absorbing pad.
[0012] Furthermore, the clamping structure includes a screw connected to one side of the shock-absorbing assembly, and one end of the screw is connected to a clamping plate via a bearing connecting seat.
[0013] Furthermore, a second shock-absorbing pad is connected to the side surface of the clamping plate, the second shock-absorbing pad being used to contact the side of the compressed air pipe.
[0014] Furthermore, a limiting slider is connected to the rear side of the clamping plate, and a limiting groove is provided on the inner surface of the shock-absorbing assembly structure, with the limiting slider slidably connected to the limiting groove.

[0016] 1. The air-cooling equipment for steelmaking plants provided by this utility model can quickly cool molten steel samples, saving time and costs and meeting the production needs of steelmaking plants. The average cooling cycle for molten steel samples using slow cooling methods is 5.4 minutes, which is too long and cannot achieve complete cooling, potentially injuring operators.

[0017] 2. The steel plant-specific air-cooling equipment provided by this utility model connects an air steel pipe to the compressed air pipeline and connects it to the sample delivery and placement air-cooling box. A ball valve is installed at the connection between the compressed air pipeline and the air steel pipe. When delivering the sample, the sample is placed in the sample delivery and placement air-cooling box and the ball valve is opened to allow the compressed air port to cool the sample in the sample delivery and placement air-cooling box, so that the molten steel sample is cooled quickly and evenly. The sample delivery operation is carried out after the sample is completely cooled.
[0018] 3. The steel plant-specific air-cooling equipment provided by this utility model, through the combined use of clamping plate, screw, bearing connecting seat, limit slider and limit groove, enables manual adjustment of the clamping plate to approach the compressed air pipeline, which can clamp the compressed air pipeline and prevent it from loosening.
