Abstract

The invention provides a corrosion-resistant composite board and a processing method thereof. By utilizing original warm-rolling and asymmetrical rolling methods, composite boards for flue can be continuously produced. The composite board comprises a titanium layer, an aluminum layer and a steel layer overlapped and compounded in sequence, wherein the thickness of the aluminum layer is 0.5-1mm, the total thickness of the aluminum layer and the titanium layer is 1-2mm, and the thickness of the steel layer is 3-40mm. By utilizing the board, an effect of reaching corrosion-resistant life of 10 years or longer of the flue can be achieved, the service life is greatly prolonged, and the composite board has extremely high popularization value.

Description

technical field [0001] The invention relates to a metal composite plate and a processing method thereof. Background technique [0002] Thermal power generation is a power generation method that uses the heat energy generated by combustibles during combustion and converts it into electrical energy through a power generation device. At present, coal used for power generation and heating in my country accounts for about 50% of the total coal production in the country. About 90% of the country's sulfur dioxide emissions are generated by coal power, and 80% of carbon dioxide emissions are emitted by coal power. [0003] The exhaust gas emitted by direct combustion of coal contains a large amount of water vapor and sulfur oxides. After cooling in the chimney, sulfuric acid is formed on the inner wall of the chimney. In addition, the exhaust gas contains a certain temperature, so it is more corrosive. [0004] my country's "Standards for the Electric Power Industry of the People'...
