Description
Technical field
The invention belongs to high silicon steel thin belt technical field.It is specifically related to high silicon steel thin belt of a kind of orientation and preparation method thereof.
Technical background
High silicon steel typically refers in particular to the ferro-silicium that Si content is 6.5wt%.Resistivity is high, mangneto is stretched owing to having for high silicon steel
The excellent magnetic properties such as contracting coefficient is low, iron loss is low under high frequency, are particularly well-suited to make high-speed high frequency motor, transformator, reactor
With shield member etc., it is advantageously implemented the miniaturization of equipment, high speed, low energy consumption and low noise.But, according to Fe-Si phasor
Understand, when Si content is more than 4.5wt%, it may appear that B2 and D03Two kinds of ordered structures so that the plasticity of alloy drastically declines are difficult
With roll forming so that high silicon steel is difficult to use rolling to carry out industrialized production.
At present, the most only JFE company of Japan utilizes chemical vapour deposition technique (CVD) industrialized production height silicon steel, its
High silicon steel product has gradient height silicon steel (JNHF-Core) and through thickness height silicon steel (JNEX-Core) two kinds, and both height silicon steel is equal
For No yield point.Owing to CVD method complex process, equipment corrosion and environmental pollution are serious, and thin plate prepared by rolling has into
Divide the advantages such as the most even surface quality is good, there is the highest industrial application value, therefore rolling has caused this skilled person
Concern.
In recent years, relevant rolling is prepared high silicon steel and is mainly No yield point height silicon steel, but rarely has being orientated the preparation of high silicon steel
Report.This is because orientation silicon steel complicated process of preparation, alloying component controls strict, the size of inhibitor particle, distribution, quantity
Accurate control, particularly texture controlling has reached ultimate attainment level.And improve silicone content and can delay or hinder secondary recrystallization
Development, first crystal grain is grown up needs higher inhibitor to suppress, and this adds the preparation difficulty being orientated high silicon steel undoubtedly, therefore
The production technology of traditional approach silicon steel can not be applied mechanically completely, need to be improved on the basis of former technique.
" a kind of method rolling the preparation high silicon steel plate of orientation " (CN104120233A), by adding C element, adds simultaneously
Various inhibitors element, uses smelting, hot rolling, normalizing process, once rolling, decarburizing annealing and intermediate annealing, it is thus achieved that orientation height
Silicon steel plate.The method processes the high silicon steel of orientation by adding various inhibitors preparation, but owing to added inhibitor kind is numerous
Many, its preparation technology is more complicated.The method is higher due to the C content added, and processes so having to pass through decarburizing annealing.The most equal
Knowing, in high silicon steel, the too high easily segregation of C content forms Fe3C and extremely disadvantageous to high silicon steel plasticity, simultaneously as the method
Complicated component, all will be extremely harsh to technological requirements such as smeltings, therefore so that the preparation of the high silicon steel that brittleness problems is serious originally
More difficult.
" a kind of preparation method being orientated high silicon steel " (CN104372238A), by thin strap continuous casting, hot rolling, warm-rolling, cold rolling,
Recrystallization annealing and purification annealing obtain the high silicon steel of orientation of high magnetic strength.The method with the addition of the multiple conjunction such as Mn, Al, V, Nb, S, N
Gold element, and C content controls 0.001 ~ 0.003%.The method C content is the highest, therefore eliminates the decarburization before high annealing
Flow process, although simplify primary recrystallization technology difficulty, but C element can deteriorate the magnetic property of high silicon steel to a certain extent, especially
It is to deteriorate iron loss.Therefore, it is thus achieved that be orientated high silicon steel core loss value higher, especially medium-high frequency iron loss P1.0/4006.75 ~
9.5W/kg。
" a kind of method utilizing rolling to prepare oriented high-silicon-steel thin plates " (CN104911322A), by hot rolling, normalizing, temperature
Roll, cold rolling, decarburizing annealing, Nitrizing Treatment, secondary recrystallization annealing obtain oriented high-silicon-steel thin plates, the method hot rolling, normalizing,
Warm-rolling process all takes oil quenching.The method adds a small amount of Mn, Al, N, S and C element, and composition is relatively simple, but due to alloy
Element is less, and inhibitor rejection ability is not enough, therefore after decarburizing annealing terminates, it is necessary to just can be orientated through Nitrizing Treatment
High silicon plate.Though the method composition is relatively simple, but technique is relatively complicated, and its orientation obtained high silicon steel B8=1.55~
1.61T, iron loss is then mainly reflected in low-frequency range, and does not provides high band core loss value.And high silicon steel is compared with common silicon steel, it is excellent
Gesture is that the low iron loss of low iron loss, especially high frequency, does not therefore embody the performance advantage of high silicon steel and common silicon steel.
Summary of the invention
It is contemplated that overcome prior art defect, it is therefore intended that provide the high silicon steel that a kind of technique is simple and flow process is short thin
The preparation method of band, the high silicon steel thin belt iron loss prepared by the method is low high with magnetic strength.
For achieving the above object, the technical solution used in the present invention is: the chemical composition of the high silicon steel thin belt of described orientation is:

Technique is simple, flow process is short, breaches the feature that existing orientation high silicon steel preparation flow is complicated.The composition of the present invention is simple, smelts
Process is easy to control, and reasonably combined due to composition, it is not necessary to adds C element, therefore saves decarburizing annealing technique, significantly letter
Change preparation technology.It is orientated high silicon steel thin belt by rolling preparation and has that technique is simple, flow process is short, the feature of low cost.
The present invention, by adding micro Cu and Al, not only improves the plasticity of high silicon steel, and the simple substance of Cu separates out simultaneously, Cu with
The Cu of S composition2S, CuS separate out, and AlN separates out and will play the effect of inhibitor, thus promote the longest of Goss texture
Greatly.Normalizing process not only contributes to inhibitor small and dispersed and separates out, and normalizing process simultaneously uses shrend, advantageously reduces high silicon steel
Long range order, thus the highest silicon steel warm-rolling and the rolling of cold-rolled process.Accordingly, it is considered to the fragility to high silicon steel is difficult
Topic, adds alloying element in the present invention and normalizing processes all not only to improve the plasticity of high silicon steel, and in order to obtain abundance
Inhibitor, promote Goss crystal grain abnormal growth.After finished products, i.e. can get the high silicon of orientation that iron loss is low and magnetic strength is high
