[0043] Reference Figure 1 The embodiment of the present invention provides a buffer plate 100 for annealing a steel coil, including an inner core plate 110 made of a high-temperature resistant and flame-retardant material; and a metal wrapping layer 120 coated on the outside of the inner core plate 110 .

[0044] According to some embodiments of the present application, the inner core board 110 is an asbestos board. Asbestos board has strong resistance to tension and pressure, can withstand high temperatures of about 1400°C, and has good thermal insulation and flame retardant effects.

[0045] According to some embodiments of the present application, the metal wrapping layer 120 is a soft stainless steel coil.

[0046] According to some embodiments of the present application, the buffer plate 100 is a circular ring structure, and the maximum diameter of the buffer plate 100 is smaller than the maximum diameter of the steel coil. Alternatively, the buffer plate 100 can also be a rectangular plate, and the length of the buffer plate 100 is smaller than the maximum diameter of the steel coil.

[0047] Reference Figures 2 to 3 An embodiment of the present invention provides an apparatus for annealing steel coils that can use the above-mentioned buffer pad 100, including a barrel-structured annealing furnace 200, the annealing furnace 200 having an inner cavity that can accommodate multiple stacked steel coils, and a buffer pad 100 is placed between each layer of steel coils; two conveying devices 400 are respectively arranged in the material taking and unloading range of the loading device, and the conveying devices 400 are used to transport the steel coils.

[0048] Placing the buffer plate 100 between the stacked coils prevents the edges of the coils from being crushed by the stacking process, thus ensuring the annealing quality of the coils. It is also important to note that the inner core plate 110 is made of a high-temperature, flame-retardant material and is wrapped with a metal wrapping layer 120 to prevent the inner core plate 110 from burning or breaking during the annealing of the coils, thereby increasing the overall service life of the buffer plate 100.

[0049] When the steel coil to be annealed is transported to the loading device by the conveying device 400, the worker manually places the buffer plate 100 on the top of the steel coil. After the steel coil with the buffer plate 100 is sent to the material-taking range of the loading device, the material-taking mechanism clamps the steel coil and is transported to the annealing furnace 200 under the transportation of the first lifting mechanism 300. The steel coils in the annealing furnace 200 are stacked in sequence from bottom to top, and buffer plates 100 are set between the steel coils.

[0050] According to some embodiments of the present application, the material picking mechanism includes a fixed frame 500 and two clamping assemblies arranged opposite to each other on the fixed frame 500. The clamping assembly is composed of two clamping claws 600. The two clamping claws 600 are arranged opposite to each other, and the two clamping claws 600 respectively clamp the two sides of the steel coil.

[0051] According to some embodiments of the present application, the clamping assembly further includes a first cylinder 700, which is mounted on the fixing frame 500, and a clamping claw 600 is mounted on the output end of the first cylinder 700. The two first cylinders 700 respectively drive the two clamping claws 600 to move closer to or away from each other to clamp the steel coil.

[0052] According to some embodiments of the present application, a support mechanism is provided at the bottom of the fixed frame 500. The support mechanism consists of two support assemblies located on either side of the fixed frame 500. The support assemblies include a second cylinder 800 and a support rod 900. The second cylinder 800 is fixedly mounted on the fixed frame 500, and the two ends of the support rod 900 are movably connected to the two ends of the fixed frame 500. The output end of the second cylinder 800 is connected to the end of the support rod 900, and the second cylinder 800 drives the support rod 900 to move on the fixed frame 500. Because the steel coil has a certain weight, the support mechanism is used to support the bottom of the steel coil to improve production safety. After the clamping assembly completes clamping the steel coil, the second cylinder 800 drives the support rod 900 to move toward the bottom of the steel coil. After the steel coil is delivered to the annealing furnace 200, the second cylinder 800 drives the support rod 900 to move away from the bottom of the steel coil, facilitating the steel coil's placement in the annealing furnace 200. This simple and practical structure. Furthermore, a second lifting mechanism 610 is provided. Specifically, the first cylinder 700 is installed on the output end of the second lifting mechanism 610. Figure 3 As shown, the material-retrieving mechanism is disposed on the conveyor device 400. When the steel coil to be annealed is conveyed to the bottom of the material-retrieving mechanism, the first lifting mechanism 300 lowers the material-retrieving mechanism. Subsequently, the clamping claw 600, driven by the first cylinder 700, moves toward the steel coil and finally clamps and secures the steel coil. The second lifting mechanism 610 starts to lift the steel coil, separating it from the top of the conveyor device 400. When it is lifted to a preset height, the second cylinder 800 starts to move the support rod 900 to the bottom of the steel coil and provides support for the bottom of the steel coil. After the material-retrieving mechanism has completely secured the steel coil, the first lifting mechanism 300 starts to simultaneously lift the material-retrieving mechanism and the coil into the annealing furnace 200. It should be noted that a buffer plate 100 needs to be manually placed on top of the steel coil to be annealed.

[0053] Specifically, one end of the clamping claw 600 facing the steel coil is an arc-shaped concave surface.
