Description

A kind of ZCT magnetic core Annealing Crystallization technique
Technical field
The invention belongs to dynamo-electric manufacture field, particularly to a kind of ZCT magnetic core Annealing Crystallization technique.
Background technology
Transformer is widely used in numerous areas, such as water heater, refrigerator, leakage plug, washing machine, automobile etc..? Europe, owing to there being direct current superposition in the alternating voltage of transmission line of electricity, general material is saturated because of DC characteristic, thus causes leakage The own distortion of magnetic core in plug and inefficacy.Thus magnetic core coil manufacturer both domestic and external all uses the method for 2 magnetic cores Reach to eliminate the purpose of distortion and inefficacy.This 2 core materials are respectively adopted punching permalloy and manganese-zinc ferrite.But perm Cost of alloy is expensive, processed complex;Although and manganese-zinc ferrite cost of material is cheap, but manufacturing cost is higher.Therefore coil is adopted Although using effect can be reached with the magnetic core of 2 different materials, but expensive, less adapt to the needs of market development.
Content of the invention
For overcoming drawbacks described above, it is an object of the invention to provide a kind of cheap for manufacturing cost and products obtained therefrom uniformity is good ZCT magnetic core Annealing Crystallization technique.
A kind of ZCT magnetic core Annealing Crystallization technique, it concretely comprises the following steps: use horizontal magnetic stove to carry out at Annealing Crystallization Reason, utilizes magnetic direction to change material atom structure, thus reaches anti-direct current purpose;First the iron based nano crystal by required specification Magnetic core is set on the steel bar in horizontal magnetic stove or steel pipe, places along magnetic field horizontal direction, in crystallization process, due to transverse current Effect, magnetic domain transversely rotates operation, through the crystallization of 3~5 hours and add magnetic treatment, iron based nanocrystalline magnet core interior atoms Structure generation radical change, thus reach the minimum loss characteristic in unit are for the soft magnetic materials.
It is material that the present invention uses iron based nano crystal, by special process process, can realize 1 iron based nanocrystalline magnet core Just can substitute the effect of former 1 permalloy magnetic core and 1 manganese-zinc ferrite core.Iron based nanocrystalline magnet core of the present invention not only becomes This is cheap and magnetic conductivity is very good.Use the magnetic core product uniformity obtained by processing technology of the present invention good, and cost phase To relatively low, good to market effect.
Brief description
Fig. 1 is the not annealed BH curve figure of same soft magnetic materials;
Fig. 2 is the BH curve figure after same soft magnetic materials uses common annealing;
Fig. 3 is the BH curve figure after same soft magnetic materials uses transverse magnetic annealing.
Detailed description of the invention
Iron-base nanometer crystal alloy is made up of iron, silicon, boron and a small amount of copper, molybdenum, niobium etc., and wherein copper and niobium are that acquisition is nanocrystalline The requisite element of structure.They are initially formed to amorphous band, are then passed through suitably annealing, and form the mixed of crystallite and amorphous Charge-coupled knit.Although this material is cheap, but magnetic property is fabulous, cobalt base amorphous alloy phase that almost can be best with in non-crystaline amorphous metal Match in excellence or beauty, but but do not contain the cobalt of costliness, be industrial and civilian medium/high frequency transformer, transformer, the ideal material of inductance, be also Permalloy and ferritic regeneration product.The present invention utilizes the advantage of above-mentioned iron based nano crystal just, by special processing work Skill, thus obtain and a kind of be applicable to the Europe special transformer core of leakage plug.As a example by soft magnetic materials MATS-2010S.
A kind of ZCT magnetic core Annealing Crystallization technique, it concretely comprises the following steps: use horizontal magnetic stove to carry out at Annealing Crystallization Reason, utilizes magnetic direction to change material atom structure, thus reaches anti-direct current purpose, the first iron based nano crystal by required specification Magnetic core is set on the steel bar in horizontal magnetic stove or steel pipe, places along magnetic field horizontal direction, in crystallization process, due to transverse current Effect, magnetic domain transversely rotates operation, through the crystallization of 3~5 hours and add magnetic treatment, iron based nanocrystalline magnet core interior atoms Structure generation radical change, under magnetic material facility detection, display soft magnetic materials, in the minimum loss characteristic of unit are, leads to Crossing test equipment and can recording the B-H magnetization curve of magnetic core, because of this characteristic, that just can effectively resist in the power transmission network of Europe is little DC current, thus allow magnetic core be operated in normal and safe scope.
The annealing of soft magnetic materials is divided into: common annealing, transverse magnetic annealing, vertical magnetic-field annealing.Annealing is that amorphous/nanocrystalline is raw Produce the most basic production link of producer, be also the key link determining product quality, so to the grasp of crystallization and understanding very Important.The squareness ratio that vertical magnetic-field annealing embodies on BH curve is very big, and being only applicable to powerful pulse transformer class product makes With not being suitable for highly sensitive ZCT class product.
Technical indicator after soft magnetic materials annealing can obtain the most directly embodying from BH curve.BH curve is magnetization song Line, with magnetic field intensity (H) as abscissa, magnetic flux density (B) is ordinate, gradually moves down variable resistor (VR), then flows The electric current entering coil will become larger, and will become larger according to H in unshakable in one's determination for the H computing formula, then the B in iron core also gradually becomes therewith Greatly, by the relation curve obtained by the change of H corresponding to the B in iron core, referred to as BH curve.To lead to a soft magnetic materials Cross the technical indicator after different annealing to contrast, will Fig. 1~Fig. 3 contrast can be seen that, after transverse magnetic annealing Soft magnetic materials all technical is superior to soft magnetic materials that is not annealed and that use common annealing.
Following table is that MATS-2010S soft magnetic materials uses different annealing way gained technical indicator to contrast:
Owing to iron based nano crystal material has excellent comprehensive magnetic energy, collect silicon steel, permalloy, ferritic advantage in one Body, i.e. high saturated magnetic induction, high permeability, low-loss and excellent temperature stability, be to manufacture Inverter Transformer Magnetic core, the optimal material of transformer core.The present invention verifies through many experiments, with the iron after special process is processed Base nanometer crystal magnetic core can substitute and realize the function that original 1 permalloy magnetic core and 1 manganese-zinc ferrite core are reached, Not changing its characteristic in the case of direct current superposition, the magnetic core obtained by the present invention is applicable to Europe leakage plug.
