Problems solved by technology

However, no one has done in-depth research on solving the problems of high-saturated amorphous material tape-making, component reduction, iron core processing, and transformer comprehensive requirements, and only realized the combination of necessary performances that are obviously superior in magnetic core manufacturing and operation. Therefore, it is found that various alloys, but each alloy is only for a part of this total combination

Description

technical field [0001] The invention relates to the technical field of amorphous alloys, in particular to an iron-based amorphous alloy and a preparation method thereof. Background technique [0002] Due to its low iron loss, high saturation magnetic flux density, high magnetic permeability and other advantages, Fe-based amorphous alloy thin strips such as Fe-Si-B amorphous alloy thin strips are widely used as iron cores for power transformers and high-frequency transformers. Based on the above characteristics, amorphous iron-based materials have been leading the way in the field of transformers for a long time. [0003] With the continuous update of silicon steel materials, the advantages of amorphous materials are relatively weakened. For example, the saturation magnetic density of amorphous materials is obviously low, and with the upgrading of silicon steel sheet rolling equipment and technology, the thickness of silicon steel sheet materials has been showing a trend of ...
