Anti-corrosion and anti-radiation method for steel plate

Abstract

The invention discloses a method for anti-corrosion and anti-radiation of steel plates. During the steel rolling process, the metal coating film is softened by the high temperature of the rolling steel and thermally fused with the hot-rolled steel plate, and a layer of metal film is coated on the surface of the rolled steel plate. For anti-corrosion protection, this method utilizes the high temperature of the rolled steel plate itself to hot-melt bond the metal film together, the bond is more uniform and powerful, and the bonding strength is high. The metal film layer has excellent adhesion and sealing performance and good corrosion resistance. It has the characteristics of heat radiation resistance, impermeability, weather resistance, and solvent resistance, and does not require heating during processing. At the same time, the thickness of the metal coating is simple and controllable, which is conducive to reducing manufacturing costs.

Description

technical field [0001] The invention relates to an anti-corrosion and anti-radiation method, in particular to an anti-corrosion and anti-radiation method for steel plates. Background technique [0002] With the continuous development of the times, my country's social economy is gradually transforming, which promotes innovation and development in various fields, and the application of steel is more and more extensive to meet the current needs; It is prone to rust and heat radiation in the environment, which leads to the combination reaction of surface atoms and oxygen to form oxides, that is, rust. Stress concentration causes the steel structure to be damaged before reaching its service life, especially after being subjected to repeated impacts, the fatigue strength will be further reduced and brittle fracture will occur; it can be seen that the corrosion of steel structures will cause harm to building safety and may cause huge economic losses Or casualty accidents, therefore, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a steel plate anti-corrosion and anti-radiation method in view of the technical problems in the prior art that the anti-corrosion method is restricted by equipment, the parts are deformed greatly, the anti-corrosion effect and the service life are poor. The high temperature softens the metal cladding film and melts it with the hot-rolled steel plate, and coats a layer of metal film on the surface of the rolled steel plate to protect the steel plate from corrosion and heat radiation. This method utilizes the high temperature of the rolled steel plate and the metal film to melt, The bonding is more uniform and strong, the bonding strength is high and no heating is required during processing, and the thickness of the metal coating is simple and controllable, which is conducive to reducing manufacturing costs
