Description
Technical field
The invention belongs to functional materials and manufacture field, be specifically related to a kind of performance by the iron-base amorphous alloy material that humidity effect is less, resistance of oxidation is stronger.
Background technology
Fe-based amorphous alloy after suitable thermal treatment process due to its uniqueness nanocrystalline/amorphous double structure and have that high saturation magnetic flux density, high magnetic permeability, iron loss are little, the soft magnetic performance of the high excellence of resistivity concurrently, be widely used in substation transformer industry at present, along with national energy-saving reduces discharging the release of policy, its consumption is also increasing year by year.
Fe-based amorphous alloy is based on Fe element, and add a small amount of amorphous formation elements Si, B forms a kind of amorphous material through rapid condensation technique, wherein the mass percent of Fe accounts for more than 90%.General manufacturing process is according to Chemical Composition configuration mother alloy, obtained amorphous band after melting, rapid condensation, then through shearing, piling up, overlap, shaping, thermal treatment, be prepared into required specification iron core after solidification.
In actual production, the mother alloy even above this main equipment of induction furnace of 1t that adopts carries out melting more, and the output of band is also very high; The weight major part weight of iron core concentrates between 50-200kg, and processing step prepared by iron core is loaded down with trivial details, use duration, as piled up, overlapping, shaping, curing schedule all needs the process operation that manually carries out one by one, and thermal treatment simultaneously and curing schedule also need to heat 4 ~ 12h in a device respectively.Such band manufactures iron core need through time of at least 2 days from piling up to, wherein most of the time band all exposes in atmosphere, in actual production, usually because other resources such as artificial, equipment such as not to possess at the reason, the band that same stove is produced needs points of multiple batches ability to enter the production line of iron core completely, and this just causes band to expose the longer time in atmosphere.
And manufacturing environment has very important impact, if composition in prior art is Fe to performances such as the losses of amorphous iron core
