Description
Technical field
The present invention, based on technical field of metal material preparation, relates to the heat treatment method of rapid solidification height silicon steel thin belt.
Technical background
Fe-6.5wt.%Si height silicon steel is because its pcrmeability is high, resistivity is high, high frequency iron loss is low and close to magnetostriction system
Number, close to zero, has the soft magnet performance of excellence, can improve electrical equipment efficiency, reduces energy consumption and noise.But due to going out of ordered phase
Existing so that Fe-6.5wt.%Si height silicon steel at room temperature plasticity is almost nil, it is difficult to use tradition hot rolling-cold rolling process processing
Become thin plate so that it is large-scale application is restricted.Although Japan uses chemical vapour deposition technique can produce Fe-by bulk industrial
6.5wt.%Si height silicon strip (Y.Takada, M.Abe, S.Masuda, and J.Inagaki, " Commercial scale
Production of Fe-6.5wt.%Si sheet and its magnetic properties, " J.Appl.Phys.64
(10), 1988,5367-5369), but that incident equipment loss is big, cost is high, pollution is heavy, production efficiency is low etc. is a series of
Problem cannot be ignored.
Owing to the Embrittlement of high silicon steel is ordered into the appearance of structure, so can be suppressed in high silicon steel by the method for quenching
The generation of ordered phase, thus improve the temperature-room type plasticity (Chinese invention patent, ZL 200710099130.5) of high silicon steel.Strengthen cold
But speed, makes high silicon steel be rapidly solidificated into strip from liquid, can at utmost suppress the generation of ordered phase in high silicon steel and grow up,
Rapid coagulation band has certain bending ability, can be wound (Chinese invention patent, application number
201410276483.8).Along with the rising of appliance applications frequency, soft magnetic materials iron loss increases, and iron core energy loss is serious.Utilize
High silicon steel thin belt prepared by rapid solidification is less due to thickness, is more suitable for using at upper frequency, particularly high-frequency inductor, high frequency
Reactor and high-frequency electric machines field, thus reduce the energy loss that iron core heating causes.
Rapid solidification Fe-6.5wt.%Si strip, due to the cooling rate being exceedingly fast, causes the internal stress that the internal existence of strip is bigger,
And there is a large amount of distortion of lattice and dislocation inside it.Therefore the strip magnetic property of rapid solidification state is poor, can't directly answer
With.For obtaining preferable magnetic property, strip need to be carried out heat treatment.Strip heat treatment, on the one hand needs to improve soft magnet performance, separately
On the one hand also need to retain certain intensity and toughness plasticity.Possess certain intensity, just can meet ferrum under high speed rotating effect
Core stands intact, and will not be destroyed by high speed centrifugation power；Possess certain room temperature tough moulding, just iron core can be carried out punching press, full
The two times punch requirement of strip after foot heat treatment.
At present, owing to there is not crystal boundary and crystal structure, to the shifting of neticdomain wall in magnetic history in Fe-based amorphous soft magnetic materials
Dynamic not obstruction so that magnetic hystersis loss is the lowest.In addition its resistivity is higher, so that iron loss is relatively low.But owing to it is saturated
Magnetic induction is relatively low, is unfavorable for device miniaturization.At present, although non-crystaline amorphous metal soft magnet performance is excellent, but due to heat treatment after
Do not possess room temperature toughness plasticity, it is impossible to meet punching core requirement, so the application difficulties in high-speed electric expreess locomotive.
From the point of view of Dui Bi, if Fe-6.5wt.%Si height silicon steel can be made to possess good comprehensive mechanics and magnetic property, due to it
Magnetostriction coefficient is almost equal to zero, and saturation induction density is higher, beneficially the miniaturization of device element and the realization of noise reduction,
Have a wide range of applications.
Summary of the invention
It is an object of the invention to provide a kind of rapid solidification to get rid of band method and prepare the heat treatment method of strip.For high silicon steel
The application conditions that strip is different, proposes suitable Technology for Heating Processing.Under conditions of requiring especially for there being obdurability to use, make
