U.S. Patent No. 5,958,153A discloses a method for adding P elements to an iron-based amorphous alloy to prepare an amorphous alloy strip with a thickness of 40-90 μm. The composition ratio of this P-containing amorphous alloy strip is (FeSiBC ) 100-x P x , where the variation range of x is 2-6 at.%, due to the addition of P element in the alloy, the Fe content is reduced, so the main disadvantage of this method is: the saturation magnetic induction of the amorphous alloy is low
The main disadvantage of this method is that the alloy melt needs to be treated at a high temperature of 1700°C
[0006] In summary, although regulating the thickness of amorphous alloy strips plays an important role in the application of amorphous strips, there is still a lack of effective technical methods for regulating the thickness of amorphous alloy strips, which is an unsolved problem in the field of amorphous alloy materials. one of the key issues of
