(II) 280kA, 300kA, 320kA, 350kA series large-scale prebaked anode aluminum electrolysis cell technology 280kA, 300kA, 320kA, 350kA series large-scale prebaked anode aluminum electrolytic cell technology realize industrialized and large-scale production. In 1996, the national large-scale aluminum electrolysis industrial test base and the 280kA large-scale aluminum electrolysis cell industrial test project passed the expert appraisal and acceptance. The successful development of the project is a milestone in the history of aluminum smelting in China. Its industrial application can increase labor efficiency by 20% to 25%, reduce the investment of tons of aluminum infrastructure by 18% to 20%, and greatly improve current efficiency. Reduce power consumption. It has been promoted and applied in Jiaozuo Wanfang. The project won the first prize of the 1998 National Science and Technology Progress Award. On this basis, 300kA, 320kA, 350kA series large prebaked anode aluminum electrolysis cells were developed. The 300kA prebaked anode aluminum electrolysis cell technology has been applied in 12 projects of 10 electrolytic aluminum plants with a designed production capacity of 2.925 million t/a. For the first time, the 320kA large-scale aluminum electrolyzer technology was put into production in Pingguo Aluminum Co., Ltd., and it has achieved large-scale production in Henan Zhongfu Industrial Co., Ltd. The large-scale pre-baked tank of 350kA realizes large-scale production in Qingtongxia Aluminum Industry Co., Ltd. and Henan Shenhuo Aluminum Industry Group Co., Ltd. This is the first time that this technology has realized industrial production in the world, which indicates that China's aluminum electrolysis large-scale tank technology has been in the forefront of the world. The construction scale of the 350kA extra large aluminum electrolysis cell of Qingtongxia Aluminum Group Co., Ltd. is 250,000 t∕a, and the 350kA extra large aluminum electrolysis cell project of Henan Shenhuo Aluminum Industry Co., Ltd. has been built 14t/a. This technology has been used in Lanzhou Aluminum. The company's 270,000 tons of new projects have been pushed to the international market and won the bid in Iranian engineering. (III) Development of 100MN hydraulic double-acting aluminum extrusion technology and equipment Shandong Jinlin Group Co., Ltd., Xi'an Heavy Machinery Research Institute, Shanghai Heavy Machinery Plant, China Aviation First Group Corporation No. 304 Research Institute, Central South University and Northwestern Polytechnical University completed the "100MN hydraulic double-action aluminum extrusion technology and equipment development" The results won the first prize of the National Science and Technology Progress Award in 2004. China's first 10,000 t (100 MN) hydraulic double-acting large-scale aluminum extrusion press production line independently designed and developed with independent intellectual property rights. In 2002, Shandong Longkou Junlin Group successfully squeezed the super long used to manufacture subway trains. Aluminum profiles. The world's largest large-scale aluminum extrusion press is a private enterprise Shandong Junlin Group project investment, designed by Xi'an Heavy Machinery Research Institute, Shanghai Heavy Machinery Factory, its automation control system through the MPI network for network control, reached 21 The international level at the beginning of the century. The production line not only fills the blank of heavy extrusion equipment in China, but also ends the history of the import of large-scale aluminum extrusion presses in China. It is a domestically produced extra large technology after the successful development of the 125,000-ton horizontal hydraulic press in the late 1960s. Another major innovation in equipment will have a tremendous impact on China's manufacturing industry, which is actively moving toward the ambitious goal of the “world factoryâ€. (4) New process for alumina production from bauxite ore-bayer method China's Great Wall Aluminum Co., Ltd., Beijing Research Institute of Mining and Metallurgy, Central South University, Zhengzhou Light Metal Research Institute, Shenyang Aluminum and Magnesium Design and Research Institute, China Nonferrous Metals Industry Technology Development and Exchange Center completed the "Bauxite Mineral Processing-Bayer Process to Produce Alumina The results of the new technology won the second prize of the 2001 National Science and Technology Progress Award.该æˆæžœå·²åœ¨ä¸å›½é“业公å¸ä¸å·žåˆ†å…¬å¸å»ºæˆ60万t∕a规模生产线。生产实践è¯æ˜Žè¯¥å·¥è‰ºä¸Žç›®å‰ç”Ÿäº§ä½¿ç”¨çš„æ··è”法工艺比：é™ä½Žèƒ½è€—50％以上，节çœå»ºè®¾æŠ•èµ„16．4％，é™ä½Žç”Ÿäº§æ€»æˆæœ¬8．86％。为å
