Fiber laser cutting machine amorphous alloy air cutting has stable characteristics, safe and reliable operation
Fiber laser cutting machine At present, the mass production and supply of amorphous strips for distribution transformers are basically monopolized by Hitachi Metals. With the increasing demand for energy conservation and environmental protection worldwide, there is a demand for amorphous alloys at home and abroad. It is getting bigger and more urgent, and my country is facing greater pressure on energy conservation and environmental protection. Therefore, the development of energy-saving amorphous distribution transformers has attracted special attention. my country currently has only a thousand-ton-level amorphous production capacity, which is far from being able to meet the domestic market demand. It is conservatively estimated that there is already a shortage of tens of thousands of tons of amorphous strips in China. In order to break the situation of such raw materials being restricted by others, it is urgent to independently develop the 10,000-ton amorphous industry. The demand for amorphous transformers is expanded and widely used in the world, and the production equipment of amorphous iron core is continuously improved and perfected in the continuous update. At present, there are dozens of manufacturers capable of producing amorphous alloy transformers in the domestic market, but there are not many that can mass-produce and reach the level. Therefore, the technical research of amorphous alloy transformers is still a key course. The production equipment of the material amorphous iron core will be better designed and improved in the future.
The development of fiber laser cutting machine setting sound for the production of amorphous ribbon will greatly affect the production of amorphous transformers. For fiber laser The design of cutting machine equipment is also a technical research difficulty. The development status and development direction at home and abroad Since the invention of the rapid quenching process by Professor Duwez in the United States in 1960, due to its unique structure, efficient preparation process, excellent material properties and broad application prospects, it has been influenced by materials science. Special attention of workers and industry. In the past 40 years, amorphous materials have gradually moved towards practical use, especially amorphous alloy strips as soft magnetic materials have been industrialized and have been widely used. In the traditional power industry, amorphous soft magnetic alloy strips are replacing silicon steel, reducing the air cut loss of distribution transformers by more than 70%, and it is known as green from the perspective of energy saving and environmental protection. In 1971, after the United States Corporation of America developed the amorphous alloy strip, the American Electric Power Research Institute and GE began to apply this strip to the manufacture of small transformers in 1982, and mass production was put into production in 1988. With the technology And technological breakthroughs, by 1998, many companies in the United States were in production, and about 1 million units were in operation on the network. Many manufacturers in Europe, Japan, etc. have also conducted research and tests on amorphous alloy materials, such as accelerated aging, transformer short circuit, and impact tests, which prove that amorphous alloys have stable air cutting characteristics and safe and reliable operation during the 30-year lifespan. In 2003, in order to solve environmental protection and recycling and reuse of raw materials, the establishment of amorphous transformers centered on Nippon Electric Co., Ltd. and Nippon Amorphous Metals Corporation. Since 1992, amorphous alloy distribution transformers have been produced, and more than 10,000 units have been installed every year. After careful calculation, its Andha Pradash state decided to purchase amorphous alloys for its distribution transformers. In other Asia and regions, such as Bangladesh, South Korea, Thailand, etc., there are amorphous alloy distribution transformer manufacturing plants, and it is estimated that there are more than 2 million amorphous alloy distribution transformers in operation worldwide. Core recovery and recycling physique to solve the worries of environmental protection resources.
