Description
Technical field
What the present invention relates to is a kind of amorphous nano-crystalline material and preparation method thereof, in particular a kind of Fe-based amorphous-nanometer crystal alloy band and preparation method thereof.
Background technology
At present; Known Fe-based amorphous, nanometer crystal alloy material is to adopt FeSiB (iron silicon boron) to add in the transition element one or several in the non-crystaline amorphous metal, thereby reaches the crystallization temperature that improves material and the purpose of material at high temperature stability, in existing amorphous, nanocrystalline strip production; The thermal treatment poor stability of the magnetic core that band is produced; Place (2-3 days above time) after the thermal treatment for a long time, can cause institute's production product performance seriously to descend, thereby cause a large amount of scrap.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of Fe-based amorphous-nanometer crystal alloy band and preparation method thereof, through changing alloy material composition proportion and the production technique in the band, improve product stability.
The present invention realizes that through following technical scheme the present invention comprises following component by weight: iron 70.5%～72.0%; Copper 1.125%～1.275%, silicon 6.95%～7.15%, ferrocolumbium 8.20%～8.50%; Ferro-boron 11.20%～12.0%, lanthanum 0.4%～0.6%.
The present invention also comprises the another one scheme, by weight, comprises following component: iron 70.5%～72.0%, copper 1.125%～1.275%: silicon 6.95%～7.15%, ferrocolumbium 8.20%～8.50%, ferro-boron 11.20%～12.0%, neodymium 0.4%～0.6%.
In the said ferrocolumbium, content of niobium is 55%～60%, by weight.
In the said ferro-boron, boron content is 7%～9%, by weight.
A kind of Fe-based amorphous-preparation method of nanometer crystal alloy band, may further comprise the steps:
(1) with after the smelting furnace preheating, add iron, be heated to iron and melt fully and seethed with excitement 5～10 minutes;
(2) add copper, silicon and ferro-boron in molten iron, be heated to hybrid metal and melt fully, and seethed with excitement 5～15 minutes;
(3) add ferrocolumbium in the hybrid metal of step (2), be heated to fusing fully, and seethed with excitement 10～20 minutes;
(4) add lanthanum in the hybrid metal of step (3), be heated to fusing fully, and seethed with excitement 30～50 minutes;
(5) it is cold to pour the hybrid metal of molten in the step (4) into cooling tank speed, forms mother alloy;
(6) with mother alloy through the fusing of spray band machine after, get amorphous thin ribbon through getting rid of the band legal system.
In the present invention, add the deflection inductance performance that lanthanum can make the band that makes, add the bias voltage may performance that neodymium can make the band that makes.
Alloy all is to be contained in inside the different hoppers of vacuum intermediate frequency furnace or vacuum high frequency furnace, struggles against through vibration in the time of different then, the entering crucible.Material alloying is small powder after the first aniseed in proper order.Because aniseed (branch ratio many) when fusing was smelted earlier, when reaching temperature, the vacuum tightness of intermediate frequency furnace or high frequency furnace the inside also was not very high; Have some oxidations; If at this time small powder inside, this part just also can oxidation, has not reached the alloy effect.And iron reaches more than 70%, and an oxidation is arranged a little, and is little to performance impact.
The present invention compares prior art and has the following advantages: the present invention is through changing the alloy material composition proportion and the production technique of producing band; The crystallization temperature and the high-temperature stability of material have not only been improved; And make product performance at least one week, can keep stable, thereby reach the purpose that improves the product over-all properties.The band that the present invention made has surface formation energy power preferably, and surface smoothness is good, and good soft magnetic performance is arranged.Required starting material are technical purity mostly, greatly reduce cost.Add REE, and after smelting into mother alloy with special process, not only improved band thermal treatment crystallization temperature and high-temperature stability, and improved the stability after the thermal treatment cooling greatly.Preparation technology is simple simultaneously, can be widely used in the aspects such as preparation of soft magnetic materials.
