Description

Technical Field

[0001] This utility model relates to the field of bar cooling bed insulation, specifically to a widening device for bar cooling bed insulation cover. Background Technology

[0002] The cooling bed system in a metallurgical enterprise's bar production line is a core piece of equipment in the post-hot rolling process, playing a crucial role in controlling and cooling the red-rolled bars. In the process flow, the multiple-length bars, after being sheared by a flying shear, are gradually cooled on the cooling bed, reducing their initial temperature from approximately 800℃ to around 500℃. They are then batched and transferred to the output roller conveyor by the cooling bed's transverse transfer device, and finally sent to the abrasive wheel saw for shearing into finished lengths.

[0003] The coverage area of ​​the cooling bed insulation hood directly affects the cooling rate of the bars, which in turn plays a crucial role in controlling the bar microstructure. However, the existing bar cooling bed insulation hoods have insufficient coverage, failing to meet the cooling control requirements for bars of various steel grades on the cooling bed. Specifically, the bar cooling bed insulation hood in the large bar processing area of ​​the long products division does not cover the effective area of ​​the cooling bed. With the development of various steel grades, this problem of insufficient coverage has become more prominent. This results in the inability to effectively control the cooling of bars of different steel grades on the cooling bed, which is detrimental to the control of the bar microstructure. Especially for high-alloy steel grades, it is often necessary to control the bars to cool to the target temperature at a slower rate.

[0004] Because existing cooling bed insulation covers cannot effectively cover various steel bar grades, they cannot meet the requirements for effective cooling control of different steel bar grades, which affects the quality and performance of some bars. Therefore, we propose a widening device for the cooling bed insulation cover of steel bars to solve the aforementioned technical problems of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a device for widening the insulation cover of bar cooling bed, so as to solve the problem that the existing technology cannot effectively cover various types of steel bars and is difficult to meet the requirements for effective cooling control of different types of steel bars.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a widening device for a bar cooling bed insulation cover, comprising an extended suspension beam and a widening insulation structure, wherein the widening insulation structure is connected to one end of the extended suspension beam via a movable joint assembly;

[0007] The end of the extended suspension beam away from the widened insulation structure is connected to the main beam of the original insulation cover of the cooling bed; the fixed end of the movable joint assembly is fixedly connected to the extended suspension beam, and its movable end is fixedly connected to the widened insulation structure. The movable end of the movable joint assembly can rotate relative to the fixed end, so that the coverage of the widened insulation structure always remains or is close to horizontal.

[0008] Furthermore, the widened insulation structure includes a frame and a fireproof cloth covering the frame. The fireproof cloth is fixed to the frame by steel wires around its perimeter. The frame is connected to the movable end of the movable joint assembly by multiple connecting brackets.

[0009] Furthermore, a first flat steel frame and a second flat steel frame are welded and fixed inside the frame below the fireproof cloth. Multiple first flat steel frames and multiple second flat steel frames are respectively provided, and the multiple first flat steel frames and multiple second flat steel frames are arranged in a crisscross manner.

[0010] Furthermore, the movable joint assembly includes:

[0011] The first connector has its upper end fixedly connected to the original insulation cover main beam, and its lower end forms a ball head;

[0012] The second connector has a recessed center on its upper end face to form a receiving space that matches the ball head, so as to achieve a wrapping fit with the ball head. The second connector can rotate relative to the outer contour surface of the ball head. The second connector has a first screw hole on its exterior that matches the connecting bracket.

[0013] Furthermore, the ball head consists of a cylindrical segment and hemispherical ends symmetrically distributed at both ends of the cylindrical segment;

[0014] The radial section of the accommodating space is a circular structure with an open top, and the maximum outer diameter of the ball head matches the diameter of the circular structure. The axial section of the accommodating space is a waist-shaped structure, and its width matches the width of the cylindrical segment.

[0015] Furthermore, the upper end face of the second connector is recessed to form a conical surface, and the opening for accommodating the space is formed at the bottom of the conical surface.

[0016] Furthermore, the connection end of the extended suspension beam and the original insulation cover main beam is provided with multiple second screw holes, and the extended suspension beam is fixedly connected to the original insulation cover main beam by bolts.

[0017] The above technical solution has the following advantages compared with the existing technology: the present invention can effectively increase the heat preservation range of the cooling bed, facilitate the control of the cooling rate of the bar on the cooling bed, and help optimize the performance of the bar.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0026] To address the problems existing in the prior art, this utility model provides a widening device for the insulation cover of a bar cooling bed. The following is a detailed description of this utility model with reference to the accompanying drawings.

[0027] See Figures 1-5 As shown, the technical solution adopted in this specific embodiment is: a widening device for the insulation cover of bar cooling bed, including an extension suspension beam 1 and a widening insulation structure 2. Specifically, the widening insulation structure 2 is connected to one end of the extension suspension beam 1 through a movable joint assembly 3.

[0028] The extended suspension beam 1, at one end away from the widened insulation structure 2, is connected to the original insulation cover main beam of the cooling bed (not shown in the figure). One end of the extended suspension beam 1 is provided with a second screw hole 11 that mates with the original insulation cover main beam. During installation, the extended suspension beam 1 is installed on the original insulation cover main beam by multiple bolts. The fixed end of the movable joint assembly 3 is fixedly connected to the extended suspension beam 1, while the movable end of the movable joint assembly 3 is fixedly connected to the widened insulation structure 2. The movable end of the movable joint assembly 3 can rotate relative to the fixed end, thereby ensuring that the coverage of the widened insulation structure 2 can always remain or be close to horizontal.

[0029] It should be specifically noted that the widened insulation structure 2 specifically includes a rectangular frame 21 and a fireproof cloth 22 covering and connected above the frame 21. The fireproof cloth 22 is fixedly connected to the frame 21 around its perimeter by steel wires (not shown in the figure). The frame 21 is fixedly connected to the movable end of the movable joint assembly 3 by multiple inclined connecting brackets 23.

[0030] Within the frame 21, a first flat steel frame 211 and a second flat steel frame 212 are welded and fixed below the fireproof cloth 22. Multiple first flat steel frames 211 and multiple second flat steel frames 212 are respectively arranged in a crisscross pattern. Preferably, the first flat steel frame 211 is perpendicular to the second flat steel frame 212.

[0031] It should be specifically noted that the movable joint assembly 3 includes a first connector 31 and a second connector 32 that are connected to each other, wherein the first connector 31 is the fixed end of the movable joint assembly 3 and the second connector 32 is the movable end of the movable joint assembly 3.

[0032] Specifically, the upper end of the first connector 31 is fixedly connected to the main beam of the original insulation cover, which can be done by welding or screw fixing. The lower end of the first connector 31 forms a ball head 311. The center of the upper end face of the second connector 32 is recessed to form a receiving space 321 that matches the ball head 311, so as to achieve a wrapping fit with the ball head 311. The second connector 32 can rotate relative to the outer contour surface of the ball head 311, so that the coverage of the widened insulation cover structure can always remain or be close to a horizontal state. The exterior of the second connector 32 is provided with a first screw hole 322 that cooperates with the connecting bracket 23.

[0033] The ball head 311 consists of a cylindrical segment 3111 and hemispherical ends 3112 symmetrically distributed at both ends of the cylindrical segment 3111. The radial cross-section of the accommodating space 321 is a circular structure with an open top. The maximum outer diameter of the ball head 311 matches the diameter of the circular structure. The axial cross-section of the accommodating space 321 is a waist-shaped structure, and its width is adapted to the width of the cylindrical segment 3111.

[0034] A conical surface 323 is recessed on the upper end face of the second connector 32, and the opening of the receiving space 321 is formed at the bottom of the conical surface 323.

[0035] The working principle of this utility model is as follows: This widened insulation cover device increases the insulation coverage area, thereby achieving the insulation effect of the cooling bed insulation cover and reducing the cooling rate of the bar stock on the cooling bed. When rolling steel grades that require a low cooling rate of the bar stock on the cooling bed, the original insulation cover main beam is rotated to the working position. The original insulation cover main beam will drive the extension suspension beam 1 to the working position, so that the widened insulation structure 2 connected to the extension suspension beam 1 can cover a wider area of ​​the cooling bed (such as the 34th tooth), slowing down the cooling rate of the bar stock, achieving control over the microstructure of the bar stock, and optimizing the final performance of the bar stock. During use, when the upward angle of the original insulation cover main beam changes, the angle of the extension suspension beam 1 will change accordingly. However, under the action of the movable joint assembly 3, it can be ensured that the coverage area of ​​the widened insulation structure 2 always remains or is close to horizontal.
