what the "aluminum saving copper" can bring me ?
In electric power industry "aluminum saving copper" applications, the technology innovation of copper aluminum composite materials in China continuously made significant breakthrough, not only won the second prize of national technological invention, put forward the "copper aluminum composite conductive flat discharge standard" also received international recognition in the near future, become the only international standard non-ferrous metal materials. 【Aluminium flat bar】
The global initiative for mass production
Copper aluminum composite material is a new type of laminated composite material in power and industrial electrical appliances industry in recent years developed , also a kind of high performance composite conductor. Copper aluminum composite material is mainly composed of aluminium and copper cladding layer, with copper conductive performance, good corrosion resistance and low cost of aluminum, light weight, etc. In use for hf wire and large current conductive row, its conductivity is almost the same as pure copper conductor.
Despite the obvious advantages materials, but lack of international way to mass production.In order to break the copper aluminum composite material technology, 2008, Beijing university of science and technology, state key laboratory of new metal material with yantai first cinda double metal co., LTD. Signed a copper clad aluminum composite billet continuous casting composite forming technology patent licensing agreement, and began the "horizontal continuous casting method to produce copper and aluminum composite conductor material" for the development of technology and equipment. 【Aluminum busbar】
"From ustb laboratory research results, subsequent to the company for the pilot and industrial research, after six years of innovative research, finally achieved today's industrialization scale production."First cinda Wang Lianzhong double metal co., LTD., general manager, said that at present, the company formed a complete set of horizontal continuous casting of copper aluminum production and processing technology and a full set of high-end metal composite materials production and processing equipment, unique in the industry.By the end of 2016, the company has r&d investment in more than 122 million yuan, test times up to thousands of furnace.
The 2013 year is the most key industrialization of copper aluminum composite casting technology research of one year. On the one hand, requires a lot of money, on the other hand, the bimetal composite casting process cooling precise control of product quality uniformity, consistency control bottlenecks."At this time can only be grasped the nettle, with Beijing university of science and technology demonstration of experts, again and again, again and again after the experiment and research, finally broke through the bimetal composite casting at the core of cooling control problem. At the end of 2013, the high performance copper aluminum composite electric flat line series products passed the national appraisal, development and application of project become pioneering technology at home and abroad."Wang Lianzhong told reporters. 【Aluminium bus bar】
"Our technology makes copper aluminum composite electric flat to large scale application, cracked long past production process, low yield, high production cost, not the disadvantages of mass production."Jian-xin xie, a professor at the university of Chinese academy of engineering, science and technology Beijing, told reporters that in the production of copper aluminum composite row in the past, only the hydrostatic extrusion method can produce good quality and meets the requirement of products, and other technical quality of the products could not reach the requirements of large-scale industrial application, and the product percent of pass is very low.
Reporter in an interview that the UK BRUKER company of hydrostatic extrusion method, can only achieve small batch production of copper aluminum composite material, can't large-scale industrialization, and complex technology, low yield, high cost, the product has been used only for the high-end market, can not meet the huge demand for the regular market.Jian-xin xie academician, according to China's first copper aluminum composite materials forming technology of continuous casting direct process cost is only half the hydrostatic extrusion method, although the two methods of timber quality, but the technology can simplify the process, reducing the production cost greatly, realize large-scale production.
Break through the transformation and upgrading of industry bottlenecks
Considering the resource security and cost, in a low price, small density part aluminum instead of copper, forming copper aluminum composite materials used for power transmission and industrial electrical conductor materials, is a hot topic now scrambling to research and development at home and abroad.Eurostar trains, for example, use of copper aluminum composite products on the electrical system, used to reduce the weight of the train.Copper flat aluminium row in the 1990 s have also been used in the world's largest high-speed ferry;In recent years in the low-voltage switchgear also use copper aluminum composite flat row of reduce the cost. 【Aluminium round bar】
"The amount of copper resources in the power industry is the largest, so the development of copper and aluminum composite conductor material, implementation to copper aluminum section, is the important way of saving copper resources, is in the national medium and long-term development plan for key support one of the development of new materials technology research and development direction."China nonferrous metals industry association, vice President of literature army said.
Now, after years of research and development innovation, the copper aluminum composite technology in the application of the power industry has paid off."High performance copper aluminum composite continuous casting direct forming technology is a kind of short process flow, high degree of automation, high efficiency of the international advanced copper aluminum composite material preparation process."Member of jian-xin xie said, compared with the existing copper platoon, the use of copper aluminum composite electric flat row with copper content can save 65% to 80%, with light weight, convenient transportation and installation, saving copper resource, low cost and high conductivity.
In addition to copper, copper aluminum composite material applied in the field of electric power has two major benefits: lightweight, low cost.In KWH cost and energy than traditional is not dominant, for new energy enterprises, cost reduction is the first.More cost-effective and better performance of copper aluminum composite materials is undoubtedly brought the Gospel to new energy enterprises, enhance the competitiveness."In 2012, when successfully trial-produced specifications copper aluminum composite parts, wind power equipment leader goldwind has become" the first person to eat crab."Fu cinda Wang Lianzhong said, at present, the production of copper aluminum composite material has been have a wide application in the field of new energy. 【Aluminum flat bar】
Copper aluminum composite material is another big application in the field of traditional transmission and distribution."This relationship to the conductor technology which direction in the future."Wang Lianzhong admits, power grid construction is the national key investment areas, our technology can be either in both performance and operation security under the premise of greatly reduce the cost of materials of electric conductor, and can reduce the dependence on the copper resources, has solved the big problem facing power industry.
"In its system, safe operation is the first priority, and new materials into there may be some risk, leading to new products in the promotion of its system, an urgent need to governments and relevant industry support."Wang Lianzhong said, for the future development, should strive to put the copper aluminum composite material as a pure copper platoon, pure LvPai outside the third new conductor material for market choice, satisfy customers more subdivided specialized needs, to provide more choices for the market, to adapt to the more diverse product distribution. 【Aluminium flat bar】
