HIDDEN DANGER OF NEGLECT: Amorphous Metal Transformer on the

Amorphous Alloy "invades" the national power grid to protect the environment, save energy and reduce emissions. Attention should be paid to Amorphous metal transformer "invades" the national power grid in the name of "Environmental Protection" , "save energy and reduce emissions" , with the overwhelming force of the "invasion" of the National Power Grid, why do I use the word "invasion" ? Because Foreign Amorphous alloy strips have long coveted the rich profits of China's transformer industry, and have been suffering from a lack of ways to make ends meet, as early as the end of the last century, Foreign Amorphous Alloy Technologies were concerned and introduced by relevant domestic scientific research institutes, as to how much taxpayer money was spent on the introduction, I don't know. I can imagine it's not a small amount. Anyway, our "introduction, digestion and reuse" has become a mode of innovation, so we don't have to use our brains, if you can't, you don't have to pay for it. At that time, the important raw material of the transformer industry silicon steel sheet was not imported from foreign countries by Wuhan Iron and Steel Co. , Ltd. and Baosteel Co. . However, oriented Silicon Steel Technology we have just mastered, silicon steel transformer technology is increasingly mature, from the current field of high-efficiency energy-saving transformer made of silicon steel transformer advantage is not bad at all. When it comes to environmental protection, the Amorphous metal transformer is not only noisy, but the amorphous alloy core can not be repaired once it is damaged, and the core itself and the transformer oil contaminated by the scrap of the core can not be reused, in the aspect of recycling, it will pollute the environment and do harm to energy saving and emission reduction. Where does our silicon steel come from? In the early years, our country was completely destitute. During the great steel-making period, we all had to tighten our belts and smash the pots to make iron. In order to catch up with Britain and the United States, we suffered a lot, in the mid-1970s, we imported high-priced cold-rolled silicon steel production technology from Nippon Steel of Japan to fill the gap that only hot-rolled silicon steel can be produced at home, but not cold-rolled silicon steel, the production and application of cold-rolled silicon steel has brought rapid development to the transformer and motor industries in China. However, due to the limited output, the market opportunities brought by the reform and opening-up in China have continuously increased the demand for silicon steel, the production line of Wisco alone can not meet the 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 import silicon steel production technology from JFE in Japan, and in a short period of time independently developed silicon steel production complete sets of equipment and production technology, quickly adapt to market demand, timely cold-rolled non-oriented, oriented silicon steel to the market, changing the situation of China's Silicon Steel Products Wuhan Iron and steel exclusively dominating the world, because the market gap is too large, in the 1990s, with the rapid development of China's power industry, especially the increasing demand for oriented silicon steel in the transformer industry, coupled with the relative shortage of domestic oriented silicon steel production, driven by high profits, the domestic market of secondary oil film expanded rapidly, a number of small and medium-sized transformer enterprises began to use a large number of secondary oil film, and derived a number of core processing enterprises. In the first eight years of the 21st century, the oriented silicon steel almost became a difficult situation, the market was mixed, and a large number of secondary oil film filled the distribution transformer market, which laid a hidden danger for the distribution transformer market. Although the recycled silicon steel, which is beneficial to the National Energy Conservation and emission reduction, poses a hidden danger to the transformer industry, as early as 2008, I once traveled all over China's secondary oil chip processing and distribution centers to collect information from the primary source, he has also written an article entitled "neglected Hidden Dangers: renewable silicon steel cores for power transformers" , which was published in the fifth issue of the Journal of electric power equipment in 2008, from "the importance of silicon steel core to power transformer" , "what is the renewable silicon steel core? What are the hidden dangers of using the renewable silicon steel core (oil sheet) , why is the market of the renewable silicon steel sheet hot, the main distribution area of the processing of the renewable silicon steel sheet and its source, output, processing mode, flow direction of the core, and the transformers made of the renewable iron core can pass the appraisal and obtain the permission of entering the network? Whether there are loopholes in the appraisal system" , "strong appeal to pay attention to the safety of rural power grid" and other aspects of the use of recycled silicon steel core concerns of rural power grid. At that time, these also aroused the attention of the competent departments of the transformer industry. Although the secondary use of recycled silicon steel was beneficial to the state in reducing emissions, the State Grid, in order to prohibit enterprises from using secondary oil chips to produce and process transformer cores, it is not allowed to carry out stress relief annealing process for the silicon steel core in the transformer industry, although it can be used to find the use of secondary oil film when spot checking, but the magnetic induction and iron loss of the silicon steel transformer core are greatly affected, because the silicon steel transformer core must pass through the stress annealing to restore the characteristics of the silicon steel in the Longitudinal Shear, the transverse shear (the silicon steel shear line Hengjianxian) , this one-size-fits-all behavior also directly leads to the silicon steel in the practical application of transformer manufacturing can not play its role completely. The price of oriented silicon steel changes in recent years in the aspect of oriented silicon steel market, taking 30Q130 produced by Wisco as an example, the market circulation price was about 15,000 Yuan/ton in the middle of 2004, and reached 30,000 Yuan/ton at the end of 2004. The market price in March 2005 was as high as 40,000 yuan/ton, at this time, the ex-factory price of Wisco was 18,800 yuan per ton. In order to ensure the good development of domestic transformer industry, Wisco changed the sales system and supplied directly to various transformer manufacturers. However, in the second quarter of 2005, its price rose directly to 27,500 Yuan/ton, and from 2006 to 2007, its ex-factory price stabilized at 35,000 ~ 36,000 Yuan/ton (both including tax price) . In March 2008, the ex-factory price rose to a staggering 38,189.97 Yuan/ton. The market circulation price once again exceeded 40,000 yuan/ton. In three years, the net increase per ton of oriented silicon steel was 20,000 yuan. In 2007, the global output of oriented silicon steel increased by about 230,000 tons compared with 2006, but it still can't meet the market demand. In the third quarter of 2008, oriented silicon steel fell sharply, leading to a decline all the way, hit bottom in early 2011, in May 2014,30Q120 market sales price has been hovering around 12,000 yuan, starting in June by the positive impact of the construction of ultra-high voltage projects, oriented silicon steel rose month by month, up to May 2005 nearly 50% . Amorphous metal transformer has seized the opportunity Amorphous metal transformer has been eyeing China's traditional silicon steel transformer market, always want to take a share of the profits, foreign production of Amorphous Alloy Strip enterprises have also taken pains to do a lot of work, on the one hand, it allowed China to introduce the production technology of amorphous tape and Amorphous metal transformer, and on the other hand, it also actively participated in the application and promotion of the Amorphous metal transformer market, they have published numerous technical articles on Amorphous Alloy materials and Amorphous metal transformer on the Internet, in journals, and in professional books, highlighting the energy saving benefits of Amorphous Metal Transformer, taking advantage of various opportunities to contact leading technical personnel in the transformer industry, and lobbying the relevant departments of the State Grid of China to play an active role in promoting the application of Amorphous metal transformer products, not to mention the introduction of China's Amorphous Ribbon production sector enterprises in the push. The price hike in the third and fourth quarters of 2014 for oriented silicon steel will give Amorphous metal transformer the best opportunity. The difference between the price of a silicon steel transformer and that of a Amorphous metal transformer is close, as a result, the authorities have a strong incentive to push the Amorphous metal transformer into the national grid, quickly taking over the distribution transformer sector with a landslide of power over the silicon steel transformers, the traditional silicon steel transformer industry can only helplessly watch the loss of the market can only look up at the sky bemoan.
