The problem of high energy consumption and high loss of aluminum alloy machining has been plagued by many aluminum processing companies and has become a bottleneck for the efficient and rapid development of the company. With the rapid growth of the demand for aluminum alloy products in recent years, the contradiction between energy waste and protection of the environment has become increasingly acute. At the time when the country puts forward the “construction of a conservation-minded societyâ€, energy conservation and environmental protection have become key issues that have been highly valued by the government. Premier Wen Jiabao stressed: "Accelerating the construction of a conservation-minded society is related to the modernization process and national security. It is related to the well-being and fundamental interests of the people and it is related to the survival and long-term development of the Chinese nation."
In the traditional aluminum alloy processing technology, whether it is to reduce the burning loss, reduce the energy consumption or improve the uniformity of the chemical composition of the product, there are mainly manual stirring or electromagnetic stirring. Due to the manual stirring, there are various defects such as large burning loss, incomplete stirring, and high labor intensity, resulting in high product cost and extremely unstable quality. The electromagnetic stirrer also has an alarming power consumption, a huge investment in equipment and operating costs, and still can not significantly reduce the disadvantages of aluminum burning. Therefore, finding new stirring methods to make aluminum melts move reasonably becomes a technical problem that all aluminum processing companies in the world are eager to overcome. The birth of the permanent magnet stirring technology not only overcomes all the defects of the traditional stirring method, but also can effectively accelerate metal melting, reduce burning loss, and improve product quality. At the same time, due to the inherent characteristics of permanent magnets, the technology has significant effects in saving energy and reducing environmental pollution.
It is reported that the application of permanent-magnet stirring technology in China stems from the scientific research achievements of Prof. Gao Qiaosan, a well-known permanent magnetic material expert in Japan, and his personal plot in his early years in China. Mr. Takahashi over three decades has been tirelessly committed to the development of relatively long magnetic materials, electromagnetic stone design, development and design of magnetic application products, has published more than dozens of influential works, in the field of magnetic material research in the world. Reputation. Prof. Gao Qiaosan applied to the Japanese government for its bottom-mounted permanent-magnet stirring device and method developed over many years in Japan in 1996 and 2004 and the melting furnace (melting furnace) with stirring device using the stirring device. Patent.
It was also learned that Mr. Gao Qiaosan established a Sino-Japanese joint venture, Hangzhou Gaoqiao Magnetoelectric Equipment Co., Ltd. (hereinafter referred to as Hangzhou Gaoqiao) in China at the end of 2004, and granted the use of the permanent magnet stirring technology he had fully invented to Hangzhou. Takahashi. In November 2004, Hangzhou Gaoqiao launched the world’s first permanent-magnet aluminum water mixer and successfully invested in Shanghai Xinge Non-Ferrous Metals Co., Ltd. (The company purchased 7 permanent-magnet mixers continuously within 3 months after its first use. ). One year later, the permanent-magnet stirrer saved only more than RMB 15 million for Shanghai Xinge Company.
This technology not only has a huge impact on China's aluminum industry, but also has caused great repercussions and sensation in the world. Among them, major Japanese and U.S. media sent special personnel to the Shanghai Xinge Company to conduct on-site interviews and applied new technologies. Space coverage. In October 2005, Thomas Tumoscheit, president of Alcoa Europe and director of global casting technology, made a special trip to Hangzhou Gaoqiao Magnetics Equipment Co., Ltd. to discuss the application and development of permanent magnet technology. As of today, in just two years, in addition to Japan and European and American markets, there are more than 50 permanent magnet stirring equipment produced by Hangzhou Gaoqiao in China alone, creating enormous economic and social wealth for aluminum processing companies.
