Abstract: high strength aluminum alloy has the advantages of low density, high strength and good hot workability, and its plates, extruded profiles and hub parts have a wide application prospect in aerospace components. As the main load-bearing member, the thick plate of high-strength aluminum alloy accounts for 30%-35% of the total amount of aluminum on the aircraft. In China, such aerospace aluminum also mainly depends on imports. From this we can see that there is still a lot of room for China to produce high-value-added high-end aluminum products.
The work of eliminating production capacity in China's electrolytic aluminum industry persists in moving forward in the face of difficulties. In 2015, the cumulative shutdown capacity of China's electrolytic aluminum industry reached about 4.4 million tons, and the scale of production reduction was about 3.69 million tons. However, judging from the statistics in the first half of this year, there is still a lot of pressure to cut capacity.
However, there is no small demand for high-end aluminum products in China and the world, especially in high-tech industries such as electronics, aviation and transportation. For example, high-strength aluminum alloy has the advantages of low density, high strength and good hot workability, and its plates, extruded profiles and hub parts have a wide application prospect in aerospace components. As the main load-bearing member, the thick plate of high-strength aluminum alloy accounts for 30%-35% of the total amount of aluminum on the aircraft. In China, such aerospace aluminum also mainly depends on imports. From this we can see that there is still a lot of room for China to produce high-value-added high-end aluminum products. Therefore, in the work of removing the production capacity of electrolytic aluminum in China, we must look forward and complete the systematic industrial upgrading in the process of eliminating production capacity, so as to obtain a long-term leading position in the international competition.
Nowadays, the electrolytic aluminum enterprises in China have embarked on the road of product upgrading, and many domestic aluminum enterprises have made great achievements in the development and production of high-end aluminum in recent years. Yuhang Aluminum has been developing aluminum plates for automobiles and aviation with high technical barriers since 2012. At present, it has a production capacity of 150000 tons of automotive aluminum sheets and 50, 000 tons of aluminum aviation materials. China Yuefeng Aluminum Group has also begun to explore the field of aerospace aluminum: in 2013, according to the specifications, characteristics and strict quality requirements of aluminum profiles in aerospace field, Yuefeng Group launched the R & D project of "7075 Aeronautical Extruded Bar"; In 2015, Yuefeng Group also jointly established Liaoning Aerospace Aluminum Alloy Research and Development Joint Laboratory with Shenyang University of Aeronautics and Astronautics and AVIC Shenfei Civil aircraft Co., Ltd.
The production of high-end aluminum is only the first step in the upgrading of the industry. In order to realize the thorough upgrading of electrolytic aluminum in our country, electrolytic aluminum enterprises are not only satisfied with providing products, but also provide perfect and accurate aluminum manufacturing solutions for high-tech industry. In the production process, aluminum enterprises should be able to work closely with production enterprises in the high-tech industry to provide unique aluminum production and processing solutions for each manufacturing demand, to the maximum extent to meet the application needs of aluminum products in the manufacturing industry. The essence of this work is to combine the electrolytic aluminum production industry with the high-tech service industry. In the reform of electrolytic aluminum industry, China's aluminum enterprises should see the great potential in the collision between their production industry and high-tech service industry, and make optimal use of the huge development opportunities brought about by the combination of the primary and tertiary industries.
In China's traditional industry, the grasp of market information plays a vital role in production enterprises. The "looking for steel net" in the iron and steel industry has shown the general direction of development in the industry. After the problem of overcapacity in China's traditional industry appeared, the vertical B2B e-commerce "looking" for generations of children flourished during this period. For example, looking for steel mesh to achieve transaction flow 90 billion in three years, and not long ago completed 1.1 billion yuan E round of financing; looking for plastic mesh B round 36 million US dollars financing, looking for pulp paper mesh A round financing US $20 million, looking for coal net A round financing US $10 million. However, in the trend of "looking" business model, electrolytic aluminum ecommerce has not yet begun to act, which points out the next development path for the industry.
China's electrolytic aluminum is the same as other commodities, and the largest surplus is structural surplus. This requires innovative market solutions to provide buyers and sellers with more accurate market information so that all aluminum products produced have their place. Deep excavation of market information and accurate use of market long tail effect to digest China's electrolytic aluminum production capacity plays a very important role in promoting the healthy development of China's electrolytic aluminum industry. Therefore, China's electrolytic aluminum industry needs to innovate together, promote the use of market information and optimize the construction of trading platform, and use the optimized market to digest the "excess" capacity.
In recent years, China's electrolytic aluminum industry has made great achievements in environmental protection. However, the remaining problems in the work have always reminded us that in the process of upgrading and transformation of electrolytic aluminum, the green transformation of environmental protection should always be focused on the center of the work.
For example, in July this year, many potential environmental problems in China's aluminum production industry began to emerge. In the investigation by the environmental department, it was found that the quality of the material yard and the surrounding environment of an aluminum company in Henan met the requirements of the standards. However, the dust phenomenon still occurs from time to time in the process of material transportation and loading and unloading, so the company has been asked to stop production and rectification. At the same time, the danger of laterite collapse occurred at the aluminum production base of another aluminum company in Henan, exposing the company's serious problems in the treatment of production waste. In the investigation and study of the electrolytic aluminum industry in China, a reporter found that up to 80% of the electrolytic aluminum in China has more or less illegal production and excessive discharge in the process of production.
The above phenomena tell us that we can not forget that the task of environmental protection upgrading in China's electrolytic aluminum industry is still very important, in the process of upgrading the industry as a whole, this aspect still has to invest a lot of energy. Especially after the upgrading of China's aluminum products to the world, the world will pay more attention to the environmental protection achievements of China's electrolytic aluminum industry. It is for this reason, China's electrolytic aluminum industry in the industry transformation, the upgrading of green electrolytic aluminum is also the top priority.
In China, the advanced aluminum enterprises have begun to act. The State Electric Investment Mengdong Energy Group Co., Ltd., which uses coal to generate electricity and smelt aluminum, has carried out a Chinese experiment on circular economy-"Huolin River Circular economy demonstration Project". This is the first domestic wind power renewable energy "coal-electricity-aluminum" green circular industry chain. That is, by absorbing wind power, reducing the cost of electricity consumption per ton of aluminum, using the principle of circular economy "changing the traditional dependent resource consumption into relying on the ecological resource cycle to develop", out of the "green counterattack road". In order to solve the biggest problem of wind power "looking at the face of God", an intelligent local power grid with coordinated operation of wind power and thermal power has been built in circular economy engineering. The smart local grid consists of 300000 kilowatts of wind power, 1.8 million kilowatts of thermal power, and an annual capacity of 810000 tons of electrolytic aluminum.
Under the pressure of overcapacity and profit compression, China's electrolytic aluminum industry urgently needs to find a new way to develop. First of all, China's electrolytic aluminum should make great efforts to eliminate backward production capacity and eliminate enterprises with low production efficiency and serious pollution. On this basis, we should broaden our horizons, adopt a multi-pronged approach, and fundamentally upgrade the whole industry systematically, so that we can win the end in the new normal state of China's economy and the new opportunities in the new era of the world economy.
