Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled plates, and more specifically, to a high-strength iron-based alloy cold-rolled plate. Background Art

[0002] Cold rolled sheet is a product made by rolling hot rolled coil at room temperature below the recrystallization temperature. It is mostly used in automobile manufacturing, electrical products, etc. Cold rolling is rolling at the recrystallization temperature, but it is generally understood as rolling using room temperature rolled materials.

[0003] Iron-based alloys are of the martensitic precipitation hardening type, and are prone to cracking and differences in the segregation of components between the head and tail of the ingot during production. In production, we mainly use high-purity raw materials, extend the electromagnetic stirring time during the smelting process, and control the melting rate through electroslag remelting, and finally produce qualified products with low segregation, high strength, and small segregation of aluminum content between the head and tail.

[0004] The existing iron-based alloy cold-rolled plates cannot be guaranteed in terms of moisture resistance and flame retardancy. During long-term use, their performance is easily affected by moisture and high temperature, resulting in their strength failing to meet use requirements. Utility Model Content

[0008] By adopting the above technical solution, the mesh diameter of the steel wire mesh is 4.5±0.5 mm, which can effectively improve the structural strength, fracture strength, tensile strength and transverse shear strength of the iron-based alloy cold-rolled plate.

[0009] The utility model is further configured as follows: the iron-based alloy plate is formed by cold rolling an iron-based alloy containing 11% chromium, 8% nickel, 5% molybdenum, 8.5% cobalt and 1.25% aluminum.

[0010] The utility model is further configured as follows: the content of glass fibers in the glass fiber board is 30% of the total weight of the glass fiber board.

[0011] By adopting the above technical scheme, the plywood with glass fiber bonded on the surface of the glass fiber board is manufactured under high temperature and high pressure, and its outer surface has high-quality moisture-proof performance, so that the glass fiber board has higher mechanical and dielectric properties, better heat resistance and moisture resistance.

[0012] The utility model is further configured as follows: the flame retardant board is made of three-layer veneer boards glued together by an adhesive.

[0013] By adopting the above technical solution, the flame retardant board is made of three layers of veneers glued together by adhesive, which is a weather-resistant, boiling water-resistant and flame-retardant plywood. The fibers of adjacent layers of veneers in the flame retardant board are glued perpendicularly to each other, and it has the performance of durability, high temperature resistance and steam treatment.

[0014] The utility model is further configured as follows: the sponge pad adopts a synthetic sponge made of low-density polyether.

[0015] The utility model is further configured as follows: the protective film is made of a medium-low viscosity PE protective film with a peeling strength of 35g / cm.
