"Expanding the application of aluminum is the key to effectively dissolving excess capacity." Luo Tiejun said in an interview with reporters. According to statistics, since 2013, the country has shut down 3.38 million tons of electrolytic aluminum production capacity. In 2013, fixed assets investment in the aluminum smelting industry fell by 12% year-on-year; from January to September this year, it fell by 31% year-on-year, and the overheating of investment in electrolytic aluminum projects was significantly curbed. At the same time, the investment in the aluminum rolling processing industry has increased significantly, from January to September this year, an increase of 26.5%. This “one drop and one liter” indicates that the investment structure of the aluminum industry is extending downstream and the structure is continuously optimized, but the pressure to resolve the production capacity is still very large.
“The effect of energy saving and emission reduction in the aluminum formwork industry is remarkable.” Chen Quanxun, president of the China Nonferrous Metals Industry Association, calculated an account. Aluminum is a renewable material. The domestic aluminum formwork can be rotated 200 to 300 times, while the wood formwork is only 3 to 5 times. The aluminum template per square meter is 25 to 30 kilograms of aluminum, and the recovery value is about 400 yuan. The use of aluminum stencils instead of wood stencils can significantly reduce the use of wood. Last year, China's building formwork used more than 800 million square meters. If 20% of them use aluminum formwork instead, they can save 160 million square meters of wood formwork, which is equivalent to saving 400,000 tons of standard coal and reducing 1 million tons of carbon dioxide. In addition, the aluminum formwork installation is 3 to 5 days less than the wood mold or steel mold, the construction speed is fast, and the stability is good, the bearing capacity is strong, the concrete surface quality is flat, the plastering process can be reduced, and the wall surface quality is good
