Description
Technical field
The utility model is related to core technology field, more particularly to a kind of tank shape amorphous band magnetic core.
Background technology
Powder core is a kind of soft magnetic materials for mixing compacting with dielectric by ferromagnetism powder.Due to ferromagnetism
Grain very little (what is used under high frequency is 0.5~5 micron), and is separated by non magnetic electrical insulating film material, therefore, on the one hand can be every
It is vortexed absolutely, material is applied to upper frequency；On the other hand due to the channel effect between particle, cause material that there is low permeability
And permanent permeance；Again because particle size is small, substantially there is no to collect skin phenomenon, magnetic conductivity with frequency change also just more
Stabilization.It is mainly used in high-frequency inductor.The magnetic electricity performance of powder core depend primarily on the permeability of powder material, the size of powder and
Shape, their fill factor, the content of dielectric, briquetting pressure and Technology for Heating Processing etc..The production process one of powder core
As include：Former material obtains-and broken-ball milling-precompressed-pre-burning-is broken-and secondary ball milling-drying-screening-grain sorting-granularity matches somebody with somebody
Than-Passivation Treatment-chemical reagent mixing-molding-heat treatment-consolidation process-grinding-insulation-finished product.Manufacturing process technique is answered
It is miscellaneous, time-consuming, consume energy also many, but core shapes species is abundant, there is O, E, I, U, EC, ETD shape, square (RM, EP, PQ), tank shape
(PC, RS, DS) and circle etc..
Nano-crystalline thin ribbon employs the super chilling solidification technology that cooling velocity is about 1,000,000 degree per second, from molten steel to thin
Band finished product one-shot forming.The magnetic conductivity of nanometer crystal alloy, Hc values are close to crystalline state permalloy high and cobalt base amorphous, and saturation magnetic strength
Bs is suitable with middle nickel permalloy, and Technology for Heating Processing is simple, is a kind of preferably cheap high-performance soft magnetic materials；Although nanocrystalline
The Bs values of alloy are less than Fe-based amorphous and silicon steel, but its high-frequency loss under magnetic strength high is far below them, and with more preferable
Corrosion resistance and magnetic stability.Nanometer crystal alloy compared with ferrite, when less than 50kHz, with the basis of more low-loss
With 2 to 3 times high of work magnetic strength, core volume can be small more than one times.Nanocrystalline magnet core production process：Metal material-melting-
Get rid of band-be wound into disk-Wound core-heat treatment-curing process-finished product magnetic core.The production process of tape wound core is simple, energy-conservation,
But core shapes are limited by band to be only capable of circularizing at present, rectangle, c-type, E types, SED types etc. are several, and core section
All it is rectangle.
With the high frequency transformer or inductance of pot core making compared with being made of E types, U-shaped, X-type magnetic core, with body
The features such as product is small, lightweight, making is simple, easy for installation.At present, pot core is all by ferrite, iron sial or other materials
Sintered after the soft magnetism powder high pressure molding bonded of matter, the common drawback of this kind of material is low (the usual 0.5T of saturation magnetic induction
Left and right), magnetic conductivity is low, high-frequency loss is high；Often making the magnetic core of a size simultaneously needs to make particular manufacturing craft, high cost；
Core production complex process, power consumption is serious.
