[0002] Alloy plates are industrial products. Thin steel plates are less than 4 mm thick, with the thinnest being 0.2 mm. Thick steel plates range from 4 to 60 mm in thickness, and extra-thick steel plates range from 60 to 115 mm in thickness. The width of thin plates ranges from 500 to 1500 mm, while the width of thick plates ranges from 600 to 3000 mm. The steel grades of thick steel plates are generally the same as those of thin steel plates; they are all flat or rectangular in shape and have high thermal strength at high temperatures.

[0003] Special alloy plates require different properties depending on the application environment. Therefore, the strength and toughness of special alloy plates used in different environments vary. This process requires bonding them together through composite methods and hot working to enhance the required properties of the special alloy plates.

[0010] The materials at the top and bottom of the base layer are the same. The base layer, two reinforcing layers, two composite layers and two wear-resistant layers are connected by hot-melt to ensure connection stability.

[0011] Preferably, both of the reinforcing layers have through-holes on their front sides, which are used to fill with thermal insulation material.

[0012] Preferably, the frame assembly includes a sealing frame and mating holes, the sealing frame being used to enclose the four sides of the alloy sheet;

[0013] The sealing frame is also made of tungsten steel, and the positions of the mating holes and the filling holes correspond to each other.

[0020] Beneficial effects:

[0021] This invention provides a special alloy plate for low-temperature brittle fracture resistance. To improve the stability and safety of the special alloy plate in low-temperature environments, the plate is divided into a base layer, a reinforcing layer, a composite layer, and a wear-resistant layer.
