      At present, the global only Hitachi metal mass production of amorphous alloy strip. Hitachi metals amorphous alloy after 07 expansion to 52000 tons in capacity, in theory, global can only produce 30.58 million KVA amorphous alloy transformer, the above production each year and we are currently about 240 million KVA compared distribution transformer production is a drop in the ocean.


      In the production of iron core, Hitachi metals machine in China's exclusive agent of amorphous iron core production line put into production, to the development of amorphous alloy transformer in our country play a strong role, with the increase of domestic core enterprise constantly, restrict the development of amorphous alloy transformer core is expected to break bottleneck.


      At present, in addition to the incredible electrical, other well-known transformer manufacturing enterprises in our country, such as suitable electrical, jiangsu huapeng, change especially electrician, hangzhou qianjiang electric group, etc were mastered the production technology of amorphous alloy transformer, once the market capacity expansion, core supply increases, more enterprises to expand amorphous alloy transformer capacity is a piece of cake.


      Overall, core and transformer production technology is not the key factor restricting our promotion of amorphous alloy transformer, amorphous alloy strip breakthrough leading to a qualitative leap.   Currently, Hitachi metal amorphous alloy strip cost up to 27000 yuan/ton, due to the strong demand downstream, Hitachi metal fitting product prices rise 20% in the near future, hope to Hitachi metals to promote the development of amorphous alloy transformer industry in China is not the reality. If, on the key technology of amorphous alloy strip in China can't breakthrough, the amorphous alloy transformer industry will collective to Hitachi metal working. Saving energy and reducing consumption has perfected social consensus on June 30, the national bureau of statistics and the national development and reform commission, the national energy leading group office jointly issued the "2005 indexes of energy consumption per unit GDP of all provinces, autonomous regions and municipalities directly under the central government gazette, the data showed that in 2005 the country's 2005 yuan GDP energy consumption is 1.22 tons of standard coal.


      Members he zuoxiu, points out that if the purchasing power parity, China's energy consumption per unit GDP is higher than in developed countries 10% to 20%; From the point of exchange rate, China's energy consumption per unit GDP 4-5 times higher than in developed countries. Announced the 2005 national ten thousand yuan GDP energy consumption as well as all over the world, and because a hard index of the 11th five-year planning regulation: the end of the 11th five-year plan, energy consumption per unit GDP than 15 at the end of the reduced by 20%. In addition, the national bureau of statistics will be announced at the end of July each area unit GDP energy consumption in the first half of 2006. According to the national development and reform commission officials, the national development and reform commission will negotiate with relevant departments, the completion as cadre assessment indicators of GDP energy consumption of binding forces.


      Saving energy and reducing consumption, carry out the scientific concept of development, transformation of the mode of economic growth, promote the adjustment of industrial structure has become the consensus of the whole society. Amorphous alloy transformer walked to the front desk of amorphous alloys are introduced in the 70 S a new type of alloy material, it adopts the international advanced super rapid cooling technique of liquid metal to 1 x106 ℃ / S direct cooling cooling rate formation thickness 0.02 0.04 mm solid thin band, has been on the atomic arrangement of short-range order, long-range disorder characteristics of amorphous alloy, the alloy has many unique properties, such as excellent magnetic, corrosion resistance, wear resistance, high hardness, high strength, high resistance rate, etc. At present, along with the electronic technology to develop in the direction of high frequency, miniaturization, amorphous superfine crystalline soft magnetic alloy material has made various magnetic device instead of silicon steel, ferrite and permalloy is applied in power industry, electronic industry and power electronic technology, used for current transformer, high-power switching power supply, inverter power supply and program-controlled exchange mechanical and electrical energy consumption per unit GDP in China 4-5 times higher than the developed countries of the amorphous alloy strip break can facilitate the qualitative leap of amorphous alloy strip is the upstream of the key materials in 1960, researchers at the university of California, the United States first found that amorphous alloy, 14 years later in 1974 the United States believe union development of iron-based amorphous alloys, the union in 1989 for the first time in the world commercial batch production of amorphous transformer core. Hitachi metals co., LTD in 2003 to buy the 50% stake in the American letter, amorphous alloy material has become the world's largest manufacturers of large shareholders.


      Currently, Hitachi plans to invest $42 million to expand its amorphous metal production capacity, the capacity from the current 22000 tons to 52000 tons, completed and put into production at the beginning of the new plant is expected to 7 years. According to the current production capacity of Hitachi metals, if Hitachi metals will all amorphous alloy exports to China, in theory, our country can only produce 12.94 million KVA amorphous alloy transformer, or for distribution transformer of 500 KVA is about 26000. 07, Hitachi metal amorphous alloy after capacity expansion to 52000 tons, the world can only produce 30.58 million KVA amorphous alloy transformer, or for distribution transformer of 500 KVA is about 60000. More output with our current each year about 240 million KVA compared distribution transformer production is a drop in the ocean. In the world only Hitachi metals under the condition of mass production of amorphous alloy strip, amorphous alloy strip has become a large-scale promotion of amorphous alloy transformer in China the biggest obstacle.


      Core of exclusive monopoly to break at the same time, due to the following characteristics of amorphous alloy, also for amorphous alloy transformer core has brought a lot of difficulties to design and manufacture of: 1, the hardness of amorphous alloy is too high, making the biggest problem is how to cut amorphous alloy iron core. To processing it with conventional cutting tools, the wear rate of tool cutting of silicon steel sheet will be 1000 times. 2, the thickness of the amorphous alloy iron core slice thin, about 0.025 mm thick, barely one over ten of the silicon steel sheet. Material surface is not very smooth, made from its core, filling coefficient is low, at just 80%. 3, amorphous alloy is very sensitive to mechanical stress, easy to broken after annealing.


      Therefore, only a few domestic enterprises grasp of amorphous alloy transformer core production technology. At present, the incredible electric (600517) shares 40% believe it has a 3000 - day port annual capacity of 4000 tons of iron core, as the nation's largest amorphous alloy transformer core manufacturing enterprise, but its products basic straight believe electrical supply, can satisfy the incredible electrical 3000 sets of 3000-500 kva amorphous alloy transformer production requirements, and most other distribution transformer enterprises "core" couldn't live.
