① amorphous alloy and its structural relationship between the atomic arrangement has not yet been fully understood, when the study further to understand, it can produce more excellent magnetic properties of amorphous alloys.
Since Pu Laina casting ② Since the development has received strong practical amorphous alloy strip. As manufacturing technology improved. Bandwidth will be more and more wide, surface quality will be improved, so that it can obtain a higher fill factor and lower cost of the product. The production glue stick of amorphous alloy films only one process (the rapid cooling of molten metal directly into the strip), so the cost of production of amorphous alloy films may have less than silicon steel.
Thin layers of amorphous alloy by the combination for the pre-laminated core piece of the amorphous alloy has been developed interests, the United States AlliedSignal developed a thickness of 0.13-0.25mm laminated amorphous alloy manufacturing technology. The material thickness according to differentglue gun requirements of the Department, with 7-12 sheets 0.025mm spray made with stacked roll, no bonding material between layers. It's slightly higher than 0.025mm amorphous alloy of iron with a loss, but still lower than 74% of high-quality electrical steel sheet, fill factor increased to 0.9. Lamination alloys successful development of manufacturing laminated amorphous alloy core transformer possible , thus broadening the range of amorphous alloy transformer capacity, the three largest stacked core transformer capacity of 500kVA. It appears, make the ordinary laminated transformer manufacturers can only use the old equipment to produce amorphous transformers and amorphous transformer capacity will be gradually increased.
③ With the expansion of the market amorphous transformer, amorphous transformer will be used for the production of special equipment, such as automatic core winding assembly lines and efficient cutting equipment to improve efficiency and product quality, reduce product cost.
In short, the amorphous phase transformer has been the importance of the transformer factory, the country has more amorphous and amorphous box-type distribution transformer substation put into operation. However, the high cost of development has always been a major obstacle.
In summary, the use of ultra-low-loss amorphous alloy instead of oriented silicon steel manufacturing distribution transformers, it is strong research and development, mechanical and electrical industry is a major innovation issues. Therefore, in the country, the first efforts to achieve localization of amorphous alloys, the use of advanced technology and equipment, find the core structure of amorphous alloy application and process methods, the various aspects of the price down, have a wide range of promotion prospects.
