Current Situation of China Ferrite Transformer

Amorphous alloys to environmental protection and energy saving "invasion" of the national grid should be taken seriously

Amorphous alloy transformer "invasion" of the State Grid, "environmental protection," "energy-saving emission reduction," the name of aggressively "invasion" of the national grid, why I use the word "invasion" because of foreign amorphous The alloy strip has long been 觊 丰 China's huge profits in the transformer industry, suffer from the mouth has been unable to, as early as the end of the last century foreign amorphous alloy technology is concerned about the domestic research institutes and the introduction of the introduction of taxpayers how much money I spent No one knows, we can imagine not a small number, anyway, we "introduce, digest and reuse" has become an innovative model, save the brains, is out of reach do not have to dig their own money. At that time, the important raw material silicon steel sheet in the transformer industry was not Wugang. Baosteel imported it from foreign countries. We can introduce amorphous alloy from silicon steel sheets. From this point of view, there is no contradiction at all. However, the orientation of silicon steel technology we have just mastered, silicon steel transformer technology matures, from the current field of energy efficient transformers for silicon steel transformer manufacturing advantage is not bad at all. Speaking of environmental protection, amorphous alloy transformers not only noise, and amorphous alloy core can not be repaired once damaged, the core itself and by the iron core debris contaminated transformer oil can not be reused, but in terms of recycling will be on the environment Cause pollution, but also adverse to energy conservation.

In early years, our country was poor and weakened. In the period of steelmaking, we all had to tighten our belt and smash pot ironmaking. In the mid-1970s, we introduced cold rolling Silicon steel production technology to fill the domestic production of hot-rolled silicon steel can not produce cold-rolled silicon steel blank, production and application of cold-rolled silicon steel to the domestic transformer, the motor industry has brought rapid development, but due to limited output, the domestic reform and opening up Market demand for silicon steel continues to increase, the production line alone WISCO has been unable to meet domestic demand, a large number of silicon steel demand, especially high-grade oriented silicon steel is still dependent on imports, Baosteel seized the opportunity to introduce silicon steel production technology from Japan JFE, and in short Time independent research and development of silicon steel production equipment and production technology to quickly adapt to market demand, promptly cold-rolled non-oriented, oriented silicon steel to market, changing the Chinese steel products WISCO exclusive dominate the world situation, due to the market gap is too large, the last century 90 In the era, with the rapid development of China's power industry, especially Is the increasing demand for oriented silicon steel in the transformer industry. Coupled with the relative lack of domestic oriented silicon steel production, driven by high profits, the domestic market for secondary oil flakes has rapidly expanded. Some small and medium-sized transformer enterprises have started to make extensive use of secondary oil flakes, And derived a number of core processing enterprises. The first eight years of the 21st century oriented silicon steel almost become a hard to find a situation, the market quite a mixed bag, a large number of secondary oil enrichment distribution transformer market, laying the hidden danger for the distribution transformer market.

Although renewable silicon steel is conducive to the national energy-saving emission reduction planted to the transformer industry

2014-2018 Amorphous Alloy Transformer Industry Future Forecast Report shows that as early as 2008, I traveled throughout China's secondary oil processing center to collect first-hand information, and wrote "Neglected hidden dangers: the power transformer can be Regenerative silicon steel core "published in the" Power Equipment "magazine 2008 fifth, from the" silicon steel core importance of power transformers "," What is renewable silicon steel core? Use of renewable silicon steel core What are the potential safety issues "," why the renewable silicon steel market is hot "," the main distribution area of renewable silicon steel processing and its origin, output, processing methods, core flow "," Remanufactured iron core transformer can be identified and access permits ? There are loopholes in the appraisal system, "" strongly urged the importance of rural power grid security, "and several other aspects of renewable silicon steel core to the rural power grid concerns. Some of these at the time also caused the attention of the competent authorities of the transformer industry, although the secondary use of recycled silicon steel is conducive to national emission reduction, but the State Grid in order to prohibit the use of secondary oil production and processing enterprises transformer core, the use of silicon steel core transformer industry Unconventional norms of the industry, to prohibit the transformer core to stress relief annealing process, although the sampling can be found when the use of secondary oil, but the magnetic core of silicon steel transformer core, iron loss is greatly affected because Silicon steel transformer core must go through stress relief annealing before being able to restore the characteristics of silicon steel in the slitting, cross shear (silicon steel cross shear line hengjianxian), this one-size-fits-all behavior also led directly to the practical application of silicon steel in transformer manufacturing can not fully play its effect.

Oriented silicon steel prices in recent years, the orientation of silicon steel market to WISCO 30Q130, for example, the mid-2004 market circulation price of about 15,000 yuan / ton, by the end of 2004 reached 30,000 yuan / ton in March 2005 the market The price of up to 40,000 yuan / ton, while the factory price of WISCO was 18,800 yuan / ton. In order to ensure the sound development of the domestic transformer industry, Wuhan Iron and Steel to change the sales system, direct supply to the transformer manufacturers. However, the price in the second quarter of 2005 rose directly to 27,500 yuan / ton. From 2006 to 2007, its ex-works price stabilized at 35,000 to 36,000 yuan / ton (all tax-included). By March 2008, the ex-factory price rose to a staggering 38189.97 yuan / ton, the market circulation price once more surpassed 40,000 yuan / ton, and the net silicon steel per tonne had a net increase of 20,000 yuan in three years. In 2007, the global oriented silicon steel output increased compared with 2006 About 230,000 tons, but still can not meet the market demand. Oriented silicon steel in the third quarter of 2008 dropped sharply, resulting in a slide all the way down to the bottom in early 2011. In May 2014, the selling price of 30Q120 has been hovering around 12,000 yuan. Since June, it has been benefited by the construction of UHV projects. Month up, as of May 2005 rose nearly 50%.

Amorphous alloy transformer to seize the opportunity

Amorphous alloy transformers have always been in the traditional Chinese silicon steel transformer market, always want to take a share of the foreign production of amorphous alloy strip companies also painstakingly done a lot of work, on the one hand to China to introduce amorphous strip and Amorphous alloy transformer production technology, on the other hand also actively involved in the application of China's amorphous alloy transformer market promotion, while they in the network, journals, books published a large number of amorphous alloy materials and amorphous alloy transformers Technical articles, focusing on the energy-saving effect of amorphous alloy transformers, the use of various opportunities to contact the authoritative technical staff of the transformer industry, lobbying the relevant departments of China's national grid, the amorphous alloy transformer product applications play a positive role in promoting, not to mention there are The introduction of China's amorphous strip production sector manufacturers fueled. The price of oriented silicon steel in the third and fourth quarter of 2014 will give amorphous alloy transformers one of the best opportunities. The spread between silicon steel transformers and amorphous alloy transformers is close, resulting in sufficient reason for relevant departments to vigorously promote the import of amorphous alloy transformers into the country Power grid, with an overwhelming momentum of silicon steel transformers quickly occupy the field of distribution transformers, and the traditional silicon steel transformer industry can only watch watch the lost market can only lament.
