Problems solved by technology

[0002] Generally speaking, the flue dust desulfurization of larger power plants is divided into wet desulfurization with GGH (GasGasHeater) and wet desulfurization without GGH. The temperature of the flue gas is about 40 to 50 ° C. When it is cold, it will form the corrosive white mist droplets (containing fluoride, chloride, SO2 and SO3, etc., and the water vapor in the air will condense into extremely corrosive chromium fluorine. acid, hydrochloric acid and sulfuric acid, etc.), so the flue gas environment after wet desulfurization, low temperature and high humidity will further deteriorate the corrosion environment of the chimney

Abstract

The invention discloses a titanium-chromium-copper alloy panel and a production method thereof. The panel is used for the production of power plant chimneys. A titanium-chromium-copper alloy panel anda substrate steel plate are included, the titanium-chromium-copper alloy panel is produced by titanium-chromium-copper alloy, and the titanium-chromium-copper alloy comprises, by weight, 0.2-0.4% ofchromium, 0.6-0.9% of copper, 0.08% of oxygen, 0.15% of magnesium, 0-0.015% of chromium, 0-0.25% of the oxygen, 0.3% of iron and the balanced titanium. The structures of the titanium-chromium-copper alloy panel and the substrate steel plate are more reasonable, the cost performance of metal panels for power plants is improved, the service life of the metal panels is prolonged, single-machine capacity is improved, designing demands are completely met, and the economical performance is high. The invention further provides a production method of the panel.

Description

technical field [0001] The invention relates to the field of steel chimneys, in particular to a titanium-chromium-copper alloy plate and a manufacturing method thereof. Background technique [0002] Generally speaking, the flue dust desulfurization of larger power plants is divided into wet desulfurization with GGH (GasGasHeater) and without GGH. The former has a flue gas temperature of about 80°C and will not immediately form corrosive droplets when it is cold, while the latter The temperature of the flue gas is about 40 to 50 ° C. When it is cold, it will form the corrosive white mist droplets (containing fluoride, chloride, SO2 and SO3, etc., and the water vapor in the air will condense into extremely corrosive chromium fluorine. acid, hydrochloric acid and sulfuric acid, etc.), so the flue gas environment after wet desulfurization, low temperature and high humidity will further deteriorate the corrosion environment of the chimney.
