Abstract
The invention discloses a manufacturing method for an amorphous alloy strip. The manufacturing method is characterized by comprising the following steps: step I, calculating corresponding raw materials according to mass percentage required by target components of the amorphous alloy strip, weighing the raw materials by a physical balance, and preparing a master alloy of Fe(100-a-b-c-x)CoaSibBcMx; step II, adding the master alloy obtained in the step I into a medium-frequency vacuum induction furnace to fuse; step III, adding an alloy ingot obtained in the step II into the medium-frequency vacuum induction furnace to carry out secondary melting; and step IV, rolling the amorphous alloy strip into a circular ring with outer diameter of 2.5 cm and inner diameter of 1 cm, and putting the circular ring into a thermal treatment furnace under protection of argon gas to carry out thermal treatment. The composition of the amorphous alloy strip is shown as follows in percentage by mass: Fe (100-a-b-c-x)CoaSibBcMx, wherein a is greater than 0 but less than or equal to 8, b is greater than 0 but less than or equal to 8, c is greater than 0 but less than or equal to 8, x is greater than 0 but less than or equal to 6, and the balance is Fe. The manufacturing method is suitable for manufacturing the low-cost amorphous alloy strip applied to a magnetic head, a transformer and a choking coil.
Description
technical field:
The present invention relates to magnetic functional material, be specifically related to a kind of amorphous alloy strips
manufacture method.
background technology:
The electron device used in the field such as power transformer, mutual inductor, its miniaturization has become a kind of development trend, and device miniaturization will be made to be achieved, and we just must develop the high soft magnetic materials of saturation induction density.Although siliconized plate has high saturation induction density, it is applied in medium-high frequency field is that loss is huge, and due to its magneticflux-density too low, can not meet the demand for development of electronics miniaturization, just progressively replace by non-crystalline material.Although it is very superior that cobalt base amorphous material shows in magnetic property, there is the magnetostriction coefficient near zero in addition, due to the price of cobalt base amorphous material expensive, limit its development in civilian.At present, cobalt base amorphous material is only applied to military affairs, space flight etc. and requires harsh field.So the higher production that result in amorphous transformer of non-crystalline material manufacturing cost does not form scale.The loss of iron-based non-crystalline alloy transformer or magnetic core is 1/4th of equal performance siliconized plate.The reduction of loss means and means the minimizing of the energy usage quantity reduction of CO2 emissions conversely, be conducive to environmental protection.
