3.2 The latest developments in the country Although the development of China's remanufacturing industry is late, it has a very good momentum. It has become one of the most important remanufacturing centers in the world, and has been at the forefront of the world in basic theoretical research and technology application development. In terms of remanufacturing policies. In June 1999, Academician Xu Binshi made a special report on "Surface Engineering and Remanufacturing Technology" at the "International Conference on Advanced Manufacturing Technology" held in Xi'an, China. He first proposed the concept of "remanufacturing" in China. In 2000, “Remanufacturing Engineering Technology and Theoretical Research†was listed as a “10th Five-Year†priority development field by the National Natural Science Foundation of China, marking the basic research of remanufacturing has been valued and recognized by the state; in 2005, “ Resource recycling manufacturing and remanufacturing has been listed as a priority development area in the “Eleventh Five-Year Plan†by the National Natural Science Foundation of China, and the academic status of remanufacturing has been further consolidated. In 2005, the National Medium- and Long-Term Science and Technology Development Plan (2006-2020) issued by the Ministry of Science and Technology, remanufacturing became one of the priority development themes and key technologies in the manufacturing field. In July 2005, the State Council promulgated documents No. 21 and No. 22 clearly stated that the state will “support the remanufacturing of used mechanical and electrical products†and listed “green remanufacturing technology†as the key to the increase of financial support by relevant departments of the State Council and local governments. In November, the National Development and Reform Commission and other six ministries jointly announced the list of the first batch of circular economy demonstration pilot areas and enterprises, and remanufactured into one of four key areas, engine remanufacturing company Jinan Fuqiang Power Co., Ltd. It is listed as a pilot unit in the re-manufacturing focus area. In April 2006, Vice Premier Zeng Peiyan of the State Council issued a report on the development of auto parts remanufacturing industry and related countermeasures and recommendations issued by the National Development and Reform Commission: "Agree to use auto parts as a pilot for remanufacturing industry and explore experience. , research and development technology. At the same time, we must consider the revision of relevant laws and regulations. In March 2008, the National Development and Reform Commission approved 14 national enterprises as a new round of “automobile parts remanufacturing industry pilot enterprisesâ€, including FAW, Dongfeng, SAIC, heavy truck, Chery and other vehicle manufacturers and Weichai and Yuchai. Waiting for engine manufacturers. In January 2009, the Law of the People's Republic of China on Circular Economy Promotion came into effect. The law states: “The state supports enterprises to carry out remanufacturing of motor vehicle parts, construction machinery, machine tools and other productsâ€; and stipulates that “the quality of remanufactured products sold must meet the standards set by the state and be marked as remanufactured in a prominent position. product". In April 2009, the State Council convened a national circular economy symposium. Li Keqiang, member of the Standing Committee of the Political Bureau of the CPC Central Committee and vice premier of the State Council, Wan Gang, vice chairman of the National Committee of the Chinese People's Political Consultative Conference, and Minister of Science and Technology of China, Xu Kuangdi, president of the Chinese Academy of Engineering, attended the ceremony and invited nine circular economy fields. Academicians and entrepreneurs attended the meeting. Xu Binshi made a speech at the meeting on "The status quo and countermeasures for the development of remanufacturing industry with Chinese characteristics", focusing on the main features of remanufacturing with Chinese characteristics that are different from those of foreign remanufacturing, and the independent research and development of remanufacturing high-tech in the circular economy pilot The application of enterprises, the contribution of remanufacturing to energy conservation and emission reduction, and the important role played by remanufacturing in resisting the global financial crisis. Academician Xu Binshi’s speech was valued by Vice Premier Li Keqiang, constantly interjecting, asking questions and discussing, showing a high degree of concern for remanufacturing. In terms of remanufacturing practices. Taking the National Defense Science and Technology Key Laboratory of Equipment Remanufacturing Technology as an example, the plasma spraying technology was used to complete the re-manufacturing problem of the hot deformation of the important thin-walled parts of the main battle tank steering mechanism. Car inspection, the life of the remanufactured planetary frame is three times that of the new product, the cost is only 1/10 of the new product, and the material consumption is 1/100; the aluminum alloy engine cylinder head of the Land-Rover in the UK appears after service. The annular pressure groove caused the airtightness to drop, and the British side could not repair it. The material molding and preparation integration technology successfully completed the remanufacturing of the Land Rover automobile aluminum alloy engine cylinder head, breaking through the international problem of remanufacturing of aluminum alloy material parts. The remanufactured engine has been put into actual vehicle evaluation and the performance is stable. In terms of remanufacturing industrialization. China has basically built a remanufacturing industry, and more and more specialized remanufacturing companies have emerged. In 2008 alone, nearly 30 remanufacturing companies were listed in the field of mechanical products, such as the Second Automobile Cummins Engine Remanufacturing Company and the Guangxi Yuchai Engine Remanufacturing Company. At present, the engine remanufacturing company Jinan Fuqiang Power Co., Ltd. is the largest remanufacturing company in China, specializing in Steyr, Cummins, Mitsubishi and other models, especially the remanufacturing of heavy-duty engines. After becoming a demonstration pilot of the national circular economy in 2005, the company strengthened cooperation with the National Defense Science and Technology Key Laboratory of equipment remanufacturing technology, applying the latest nano surface engineering technology and automated surface engineering technology to the production line, significantly improving the used engine. The remanufacturing level and remanufacturing rate have now reached an annual capacity of 25,000 engines for remanufacturing. Our army is very important for remanufacturing. In recent years, we have established the first military vehicle remanufacturing production line of the entire army in a military factory. The re-manufacturing capacity of the first-class annual re-manufacturing capacity is nearly 10,000, mainly for Dongfeng, Liberation, Hongyan, Jetta, Engine remanufacturing of Santana, Cheetah and other models.
