China's first high-precision aluminum cold rolling line put into operation

Yesterday, China Aluminum Corporation's first high-precision aluminum cold rolling mill production line with the world's advanced level in another major project invested by the city was completed and put into operation in the Southwest Aluminum Group. At this point, Southwest Aluminum will have an annual production capacity of up to 800,000 tons, which can produce large-scale, specialized production capacity for high-precision aluminum materials such as can-making materials, bottle cap materials and aluminum foil billets, and at the same time replace imported products in large quantities to meet the future market. Demand for high quality, high performance cold rolled aluminum sheet.

Aluminum processing cold rolling is the cutting-edge production technology in today's world non-ferrous metal industry. At present, only the United States, Japan and other aluminum processing advanced countries have built this production line. According to the person in charge of Southwest Aluminum, the production line has been completed and put into operation for 5 years since it was started in April 2006. The main equipment includes a 2000 mm double-stand tandem cold rolling mill jointly developed by SMS Siemag AG and ABB in Germany and provided by Siemens. The 2000 mm single-stand cold rolling mill, as well as the high-speed edge trimmer and aluminum coil three-dimensional, plane intelligent logistics management system, integrates the world's highest level of aluminum sheet metal production technology and equipment.

Chinalco said that the production line is based on the successful establishment of Southwest China's first international advanced hot rolling line, which fully leverages the equipment advantages of the hot rolling line to meet the current market demand for a large number of high-quality aluminum strips. , And supporting the implementation of another with the international advanced level of aluminum strip project. After the project is completed, it will form a production capacity of 250,000 tons of aluminum cold rolling, which will not only enable Southwest Aluminum to enter the ranks of world-class aluminum processing companies, but also advance the pace of Xipan Industrial Park to “China's aluminum processing capital”, and will also allow China's transition from a large aluminum processing country to a strong aluminum processing country has completely ended the history of China’s long-term dependence on imports of high-precision aluminum products and its monopoly by foreign multinational companies. This is a landmark project that has significant significance.

Municipal Health** Deputy Director Hu Health, Deputy CPPCC Wu Jianong, Vice Chairman of the China Nonferrous Metals Industry Association Wenjun, member of the China Aluminum Corporation Party Group, President of China Aluminum Corporation Luo Jianchuan attended the completion ceremony.

In addition, yesterday, the foundation of the project of the annual production capacity of 220,000 tons of aluminum and aluminum alloy smelting and expansion production lines of the Southwest Aluminum Group was established. The project is expected to be completed and put into operation in one and a half years. The project mainly produces aluminum and aluminum alloys for the production of high-precision civil aluminum strips. Flat ingots. At the same time, Sino Aluminum Sapa Special Aluminum (Chongqing) Co., Ltd., a joint venture between China Aluminum Corporation and Sweden Sapa Group, was unveiled yesterday and officially settled in Xipeng Industrial Park.

According to reports, the smelting process is an important basis for physical metallurgy of aluminum and aluminum alloy materials, and is the first step in the multi-stage processing of deformed aluminum products. Although SW China's existing fused cast system can produce more than 170 alloys, more than 70 specifications of square, round, hollow aluminum and aluminum alloy ingots, but with the chill continuous rolling production line, plate production line has been put into production, this set of casting The system can no longer meet production needs.

The person in charge of Southwest Aluminum stated that after the project of smelting and expanding production line is completed, various technical indicators will reach the international advanced level, with advantages such as high production efficiency, excellent production quality, energy saving and environmental protection, etc., thereby further enhancing the digestion capacity of aluminum processing material waste. The ingot supply capacity and the equipment level of the casting capacity.

Chinalco Sapa Special Aluminum (Chongqing) Co., Ltd. is Chinalco's first Sino-foreign joint venture project in aluminum processing industry. The initial investment of the project will exceed 600 million yuan. After commissioning, it is expected to produce 20,000 aluminum rails and body modules for rail transit annually. Tons, the formation of China's own high-end rail profile brand, to meet the city and even the country's high-end rail transit aluminum market demand.

Vice Chairman of the Standing Committee of the Municipal People's Government Hu Health, Vice-Chairman of the CPPCC National Committee Wu Jianong, Vice Chairman of the China Nonferrous Metals Industry Association Wenjun Literature, Member of the China Aluminum Corporation Party Group, President of China Aluminum Corporation Luo Jianchuan attended the foundation stone laying ceremony of the casting project. The opening ceremony of Chinalco Sapa (Chongqing) Company.
