Abstract
The invention relates to a production method for a magnetic material, in particular to a low-permeability, low-power consumption Fe-Si-Al powder material and a production method thereof. In the process of producing Fe-Si-Al powder, a melt-spinning machine rapid cooling method is adopted to produce a strip, and the cooling speed is 104 DEG C/second to 106 DEG C/second; and moreover, the flat Fe-Si-Al powder is produced by atmosphere-protected mechanical crushing. The invention has the advantages that: the oxygen content of the powder is greatly decreased, the grain size of the product is reduced, consequently, the loss of the Fe-Si-Al product is reduced, and the properties of the product are enhanced.
Description
Technical field
The present invention relates to the manufacture method of magnetic material, relate in particular to iron aluminum silicon powder powder material of a kind of low magnetic permeability, low-power consumption and preparation method thereof.
Background technology
At present, along with the reform of energy technology, magnetic material is fast-developing, and in so many magnetic materials, the iron silica-alumina material is because of higher magnetic flux density, and lower loss and high performance-price ratio are widely used extensive market in middle-size and small-size device.But because its flouring technology causes its loss larger, perhaps function admirable but output is less is not found large-scale manufacturer substantially, trend for the magnetic material fast development, the product loss is low, and technique is simple, and the flouring technology that can be mass-produced has been active demand.
For this reason, the Chinese invention patent application of applicant application (application number: 201110404623.1 applyings date: 2011-12-08) disclose the low-loss sendust soft magnetic material of magnetic permeability μ=26, this sendust soft magnetic material is made through surface treatment, compressing and heat treatment by iron sial powder, the weight content of Si is 8.5%～10% in the iron sial powder, the weight content of Al is 5%～6%, the weight content of Ni is 0.5%-1%, the weight content of Cr is 0.5%-1%, and surplus is Fe.This patent has kept good inductance value by adding Ni and Cr element, in the time of higher quality factor, has improved saturation induction density; Improve the direct current biasing ability, and reduced loss value.
But in the manufacture craft of sendust powder, the inventor finds that oxygen content is larger for the impact of iron sial powder, and the oxygen content of product is lower, and properties of product are better.And in traditional atomization process, the water atomization oxygen content is high, and loss is large, is difficult to satisfy client's demand; The gas atomization Costco Wholesale is high, is not suitable for large-scale production, and product does not have competitiveness; And general pass through the mode that ingot casting carries out the alloy fragmentation, because alloy is block large.The broken time is longer, causes heat large, and is long with the contact with air time, so that oxygen content improves, affected the performance of product.
Summary of the invention
In order to solve above-mentioned technical problem, an object of the present invention is to provide the iron aluminum silicon powder powder material of a kind of low magnetic permeability, low-power consumption, this iron aluminum silicon powder powder material greatly reduces the oxygen content of powder, reduced the product grains granularity, thereby reduce the loss of iron sial product, promoted properties of product.Another object of the present invention provides the preparation method of the iron aluminum silicon powder powder material of a kind of low magnetic permeability, low-power consumption.
In order to realize first above-mentioned purpose, the present invention has adopted following technical scheme:
The iron aluminum silicon powder powder material of low magnetic permeability, low-power consumption, described iron sial powder adopt in flouring technology and get rid of band machine high speed cooling means band processed, and cooling rate is 10
4～10
6℃/second; And the Mechanical Crushing by atmosphere protection, make flat iron sial powder.
As preferably, the weight content of Si is that the weight content of 9%～10%, Al is 5%-6% in the described iron aluminum silicon powder powder material.
As preferred again, also comprise the Cr of 0.5%-1% weight content in the described iron aluminum silicon powder powder material.
As preferred again, also comprise the Ni of 0.5%-1% weight content in the described iron aluminum silicon powder powder material.
In order to realize second above-mentioned purpose, the present invention has adopted following technical scheme:
The preparation method of the iron aluminum silicon powder powder material of low magnetic permeability, low-power consumption, the method adopt in flouring technology and get rid of band machine high speed cooling means band processed, and cooling rate is 10
