And then the steel pipe manufacturing industry: expected and emerging industries Few people will notice that our tens of thousands of billion of equipment assets each year for reasons such as wear and corrosion make the equipment discontinued scrap losses caused by up to one hundred billion yuan, and the retirement of a large number of devices has caused tremendous pressure on the environment and resources , it is also virtually caused a huge waste. As a result, a new industry "and then steel pipe manufacturing" has been more and more the attention of the industrial countries. The so-called re-steel pipe manufacturing to advanced technology and industrial production as a means of restoration and improvement of waste electrical and mechanical equipment, so that recovery performance even for new performance, extended equipment life. And then steel pipe manufacturing in energy, materials, and reducing consumption, reducing pollution and mention Few people will notice that our tens of thousands of billion of equipment assets each year for reasons such as wear and corrosion make the equipment discontinued scrap losses caused by up to one hundred billion yuan, and the retirement of a large number of devices has caused tremendous pressure on the environment and resources , it is also virtually caused a huge waste. As a result, a new industry "and then steel pipe manufacturing" has been more and more the attention of the industrial countries. The so-called re-steel pipe manufacturing to advanced technology and industrial production as a means of restoration and improvement of waste electrical and mechanical equipment, so that recovery performance even for new performance, extended equipment life. And then steel pipe manufacturing in energy, materials, and reducing consumption, reducing pollution and improving the role of economic benefits is huge. The data show that 48 million people engaged in steel pipe manufacturing in the United States, annually generating $ 53 billion of output value. Jiangzai steel pipe manufacturing industry to develop into a new industry is not only conducive to China's development of circular economy as large a device, but also conducive to China's industrialization process to achieve sustainable development. And then the steel pipe manufacturing: turning waste into treasure Of re-steel pipe manufacturing development has great potential as an important way to develop a recycling economy, effective conservation of resources, Chinese Academy of Engineering on the recent meeting of China's Circular Economy Development Forum 2005 Annual Meeting, Zhang Yanzhong. "China's re-steel pipe manufacturing promising." Zhang Yanzhong upgrading of scrap cars, for example, said, According to statistics, in 2010, car ownership in China will reach 45310000-47000000 cars scrapped each year in the future will be at 200 million more than estimated in accordance with this trend, 2010, 30 percent of the scrapped vehicles in China for re-manufacture of steel pipe, the annual sales record 36 billion yuan, the recovery of value-added of 49 billion yuan, 18 million to solve the employment reduce carbon dioxide emissions by 2.3 million tons. It is understood that in recent years, every year at least 26 million cars scrapped. Scrapped the number of China's mechanical and electrical products is quite amazing, there is 2.1 million in 2000 to be scrapped car. The car then steel pipe manufactured parts, including the internal combustion engine, transmission, clutch, steering, starter, carburetor, brake shoes, pumps, air-conditioning compressor, wiper motors, pumps, brake action cylinder, power control pump and buffers. Re-steel pipe has been attached to the manufacturing sector in many developed countries, and has formed a large-scale re-steel pipe manufacturing industry group. 2003 re-steel pipe manufacturing average annual output value reached 40 billion U.S. dollars, 0.4 percent of its GDP. Re-steel pipe manufacturer database, there are 84 different types of products can be re-steel pipe manufacturing, including auto parts, medical diagnostic equipment, magnetic resonance images and copiers. Chinese Academy of Engineering, said Professor Xu Binshi, then steel pipe manufacturing industry is a huge market prospects, mainly reflected in the resource efficiency, environmental benefits and social benefits. And then the steel pipe manufacturing project can save a lot of materials and energy. Since then steel pipe manufacturing is the direct use of the product components for production, so most of the material in the first steel pipe manufacturing the original product about 85% □ □ approximately 85% ~~ 95% "and energy □ save, and reduce the due to product parts needed for the production of materials and energy of the primary ore mining. Some data indicate that the U.S. steel pipe manufacturing industry with an annual output value of GDP in 2002, 0.4 percent. China's GDP in 2020 is expected to reach $ 4 trillion, the United States in 2002, steel pipe manufacturing level as the 2020 target, and then re manufacture of steel pipe industry output value will reach $ 16 billion. Then steel pipe manufacturing engineering in the industrial countries has been extensive research and industrial applications. Europe has been passed in favor of re-steel pipe manufacturing engineering related laws and regulations, and is Germany building in Europe and then steel pipe manufacturing technology centers. The European Union in 2000 adopted the new requirements of an environmentally friendly future all EU car users will enjoy a free used car recycling. Renewable utilization of scrap cars in 2015 will reach 95%. China's current re-steel pipe manufacturing industry is still the main stay in the phase of theoretical research, then steel pipe manufacturing industry can bring economic and social benefits of a clear understanding of the companies or investors are not the only two a re-steel pipe manufacturing company, the world has more than 73000 then the steel pipe manufacturing company, may be the smallest country in the global proportion of industry. China in the late 1970s early 1980s, the introduction of major machinery and equipment since 2001 in succession facing retirement, and our existing about 400 million machines, numerical control machine tools for less than 3 percent, while developed countries have already more than 20 %. Advanced nano-surface engineering technology and transformation of NC technology to transform the use of used machine tools to be effective in restoring the mechanical properties of the old machine to improve the control and processing accuracy in order to achieve accurate and intelligent processing equipment, the cost of comparable to purchase a new machine to save 60-80%. In addition, outdated and obsolete scrap computer, household appliances, such as upgrading is then steel pipe manufacturing content. Since 2003, China has entered the peak of the washing machine, television, computers and other household appliances scrapped annual scrapping volume in more than five million units, should accelerate the development of generic technology of waste home appliances recycling, key technologies and upgrades to steel pipe manufacturing process, and environmental pollution to a minimum. Then steel pipe manufacturing to become a pillar of steel pipe manufacturing Chinese Academy of Engineering Xu Bin-shi as early as 2004 national circular economy work conference called for our country should be committed to "steel pipe manufacturing," built of steel pipe manufacturing industry a pillar industry, and establish the system of related supporting industries, stimulating the national economy to achieve re-employment and sustainable development. Xu Bin, said that after a further demonstration of the Chinese Academy of Sciences, Chinese Academy of Engineering and Chinese Academy of Social Sciences, and then the steel pipe manufacturing and self-repair as a steel pipe manufacturing areas of priority development themes and key technologies to enter the national long-term development outline. He said that according to the development planning of preliminary demonstration results, the research objectives can be summarized in the next 20 years the steel pipe to manufacture advanced IT, micro and nano technology, bio-technology with independent intellectual property rights as a breakthrough self-healing and re-steel pipe manufacturing a key technology groups; breakthrough adaptive, self-healing capabilities of advanced materials research and industrial preparation technology; breakthrough in advanced intelligent, self-repair detection and control technology. At the same time to develop standards for discarding waste products and the development of quality standards and then the steel pipe manufactured products. Binshi said, since the mid-1990s of the last century, China continues to enterprises joined to re-steel pipe manufacturing the practice of exploring to, such as the Ministry of Agriculture, agricultural mechanization Research Institute conducted a crawler tractor of re-steel pipe manufacture, achieved a certain economic social benefits; Shanghai Volkswagen Joint Development Co., Ltd. Santana car engine and then steel pipe manufacturing its R & D, production and sales have begun to take shape; Shenyang "road" laser re-steel pipe manufacturing company of a large roll with the turbine The blades were then steel pipe manufacturing solve the problems of the traditional process of surfacing and other maintenance can not be solved, the annual output of 50 million. Engine, for example, steel pipe manufacturing, the engine's energy consumption for steel pipe manufacturing half of the engine, the value of labor for the manufacture of steel pipe 2/3, only 20% of the steel pipe manufacturing and material consumption. This advanced surface and then the steel pipe manufacturing technology is the engine re-manufacture of steel pipe. Waste electrical and mechanical products, the main drawback is the surface of the part failure, such as corrosion, friction wear and fatigue crack started from the part surface. Surface failure is to shorten the product life, increased maintenance funding. The whole of the damage is often some parts damage caused by the damaged parts are often individual work surface failure. If the failure of parts of the vulnerable parts of the surface engineering technology be restored, and starting from the idea of preventive repair superficial to be strengthened, could constitute the improvement of overall performance. At present, special-shaped micro-pulse cold welding technology, advanced surface coating of technology to the steel pipe manufacturing technology has been widely used in the engine re-manufacture of steel pipe, Jinan Iron and Steel Group Corporation has a large number of the steel pipe to manufacture product. Relevant experts believe that China's national conditions, should gradually establish their own distinctive steel pipe manufacturing industry legal system. Relevant laws and regulations and scrap cars, electronic appliances, agricultural tractors resources of individual regulations should be introduced; established steel pipe manufacturers responsibility, resource companies and product certification system, to develop appropriate rewards and penalties. Establishment of scientific management and operation of a coordinated reverse logistics system; public special funds to promote enterprise and private capital investment in the field as soon as possible to promote its industrial development; steel pipe manufacturing of machinery and electronic products, use, recycling, and then the steel pipe manufacturing, re-use closed-loop logistics chain, the formation of a new set of social, economic and environmental benefits as one of the resources industry group. Setting up a dedicated fund to support the steel pipe to manufacture the basic theory and key technology research and development, enhancing the information technology of obsolete Steel pipe
manufacturing, upgrading; introduction and digestion and absorption of foreign advanced technology, equipment and management experience, improve our country and then steel pipe manufacturing recycling technologies and management systems.
