General Manager Li Fengji requested at the meeting to go all out to speed up the process of building the production line and ensure that he would offer a generous ceremony for the 90th anniversary of the founding of the Party with the excellent results of full production.

——On May 1st, 2011, after the hard work of Chinese and foreign constructors, a single rack of cold rolling mill production line was successfully tested and the production line was initially fully connected.

——On June 28, 2011, Chinese and foreign technical personnel spent five and a half years working arduously. As a major landmark project in the history of aluminum processing in China, the cold rolling line was completed and put into production. This will greatly improve the technical level of China's aluminum processing industry equipment, provide the market with much-needed high-quality, high-precision, high-grade aluminum processing cold-rolled products, import quantities in large quantities.

The background of the tandem cold rolling production line is to greatly improve the overall equipment level of aluminum processing in China, improve the supporting production capacity of high-precision products of the Southwest Aluminum Corporation, and achieve the “high” of canning materials, bottle cap materials, printing PS substrates, and aluminum foil blanks. With regard to the large-scale and professional production of sophisticated aluminum materials, Chinalco decided to build the first aluminum processing cold rolling line with the most advanced annual production capacity of 250,000 tons in China Southwest Aluminum Corporation. On April 23, 2006, on the basis of the completion of the previous stage, the cold rolling line was officially started construction. As an important landmark project in the development of aluminum processing in China, the construction of production lines has attracted wide attention from all walks of life.

Aluminum cold rolling is the cutting-edge production technology in the world today. At present, only aluminum processing advanced countries such as the United States, Japan, and Germany have established such production lines. Chinalco Southwest Aluminium Cold Tandem Rolling Project is the only aluminum processing cold rolling line built in the world in the past 18 years. Its main equipment includes the 2000mm double rack cold that was jointly built by the world famous German SMS Siemag and ABB. Continuous rolling mill; 2000mm single-stand cold rolling mill provided by the world-famous Siemens company; and high-speed trimmer and aluminum coil three-dimensional, plane intelligent logistics management system, etc., integrating the world's highest production technology and equipment of aluminum strip Level.

The production line is the Southwest Aluminum company's successful construction of China's first international advanced level of hot rolling production line, in order to give full play to the equipment advantages of hot rolling production line, to meet the needs of the national economy, the urgent need for a large number of high-quality aluminum sheet and strip, and supporting the implementation of Another is the first time in the country with the international advanced level of the aluminum strip project, another major project with a "milestone" significance. At the same time, it is an important project of China Aluminum Corporation adhere to the scientific concept of development, relying on scientific and technological progress, and constantly improve the industrial chain, the implementation of leap-forward development of aluminum processing strategy, is also a joint venture between Chinalco and Chongqing to build aluminum companies based on aluminum An important step in the "China's aluminum processing capital" with Chongqing's Xi Peng Characteristic Industrial Park as its core.

The production line began to be leveled in December 2005. Construction was officially started in April 2006. By the end of December 2008, the installation of double-stand rolling mill equipment was completed and the production line plant and peripheral auxiliary projects were also completed. In May 2009, the two-stand rolling mill was successfully tested with one-off materials and rolled out the first aluminum cold rolling mill in the history of aluminum processing in China. The success of the single-stand mill rolling stock test on May 1, 2011 marked the initial completion of the cold rolling mill line.

Cold rolling mill production line is another important landmark project in the history of aluminum processing in China. The completion and commissioning of the production line not only can greatly enhance the level and technical level of aluminum processing equipment in China, but also realize the substantial substitution of imported high-precision aluminum materials. It also promotes the pace of construction of "China's aluminum processing capital", enhances Chongqing's economic strength, and boosts local economic growth. The economic development has a very important significance. Since the project was established, it has attracted extensive attention from the Chinese and foreign industries and all walks of life. It has been highly valued and fully affirmed by the relevant national ministries and commissions, Chongqing Municipality, Chinalco Corporation, and relevant departments and domestic aluminum processing experts. Chongqing City gave high hopes for the project and gave strong support.

After the tandem rolling production line is completed and put into operation, the annual capacity of the Southwest Aluminum Company will reach 700,000-800,000 tons, and will provide the market with much-needed high-quality, high-precision, high-grade aluminum processing cold-rolled products to realize the can-making, Large-scale, specialized production of high-precision aluminum materials such as bottle caps, printing PS substrates, aluminum foil blanks, etc., and large quantities of imported substitutes to meet the growing market demand for high-quality, high-performance cold-rolled aluminum sheet strip The needs of the Southwest Aluminum enterprises into the ranks of world-class aluminum processing companies.

At present, the Southwest Aluminum Corporation is an integrated ultra-large aluminum processing enterprise with the largest production scale, the most advanced technology and equipment, and the most complete product variety specifications. The completion of the cold rolling line has consolidated its position as the “leading” aluminum processing industry. Enterprises in the fierce competition in the global economy will continue to play a decisive role in the rapid development of the industry; to improve China Aluminum Corporation and even China's aluminum processing equipment level and technical level, improve Chinalco's international competitiveness, so that China from the aluminum processing giant The advancement of aluminum processing power, as well as the promotion of the "China's aluminum processing capital" and the promotion of local economic development are all of great significance.
