Problems solved by technology
During the annealing of roll-type production, the aluminum alloy is in the form of a coil. Because it is not fully unfolded, the oil on the surface is not easy to completely volatilize, and there will always be a part of it that will remain on the surface of the aluminum alloy to form oil spots, which will also affect the performance. The difference is large. At the same time, because the aluminum alloy is in the shape of a coil, it takes a long time to cool down, which reduces the production efficiency.

The invention provides a method for producing aluminum alloy sound barrier plates, which includes: uncoiling a coiled aluminum alloy sheet to obtain an aluminum alloy strip; cleaning the aluminum alloy strip for the first time; passing the aluminum alloy strip through an air-cushion furnace at certain speed, and continuously annealing the aluminum alloy strip in the air-cushion furnace, wherein the temperature of a heating area of the air-cushion furnace is the set annealing temperature and the temperature of a holding area of the air-cushion furnace is the set cooling temperature; cleaning the annealed aluminum alloy strip for the second time; stretching and strengthening the aluminum alloy strip; coiling the aluminum alloy strip to obtain an aluminum alloy coil; precisely shearing the aluminum alloy coil at fixed length to obtain finished aluminum alloy sheets; and machining the finished aluminum alloy sheets into sound barrier plates in special shapes. Difference of surface performances of aluminum alloy is eliminated, while production time is shortened and production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of environmental protection, and more specifically relates to a production method of a sound barrier plate used for isolating noise. Background technique [0002] With the continuous development of my country's high-speed rail technology, my country's high-speed rail construction has entered a stage of rapid development in recent years, which has brought great convenience to people's daily travel and business development, but its high-decibel noise pollution also brings people Life has caused a greater impact, therefore, the sound barrier panels that can reduce the noise pollution of high-speed rail have gradually gained people's favor. [0003] After research, it is found that aluminum alloy can better meet the technical requirements and working effect of the sound barrier plate for high-speed rail. Therefore, aluminum alloy plate is widely used in the production of sound barrier plate for high-speed rail. ...
