Description
Technical field
The present invention relates to a kind of preparation methods of inexpensive low-loss soft-magnetic alloy powder, refer in particular to a kind of using non-real
Air atomizing iron sial powder preparation method.
Background technique
Powder preparation is that the first step of production alloy magnetic powder core is also one of most critical, and conventional preparation method has atomization
Method, crush method etc., aerosolization is to prepare a kind of common methods of metal powder, wherein can be divided according to the difference of smelting equipment
For vacuum aerosolization and non-real air atomizing.When preparing high value powder such as iron nickel, iron nickel molybdenum, there is the use of amount of powder producer
Vacuum aerosolization mode prepares high-quality iron nickel, iron nickel molybdenum powder, is exactly when preparing aerosolization iron sial there are also one kind, due to
In iron sial fusion process can because high-temperature oxydation generates a large amount of clinkers, be very easy to obstruction atomization let slip a remark and spray gun, institute
It is prepared in a manner of frequently with vacuum melting.
Although the powder quality that vacuum aerosolization prepares is good, its equipment investment is big, and complex process causes powder
Yield is by equipment limit and cost remains high.
Although existing non-real air atomizing is advantageous on equipment capacity and cost, the powder in melting and atomization process
Oxygen content can increase in end, and as the aluminium in Aluminum steel liquid can be because with the oxygen in atmosphere reacting for fierceness, oxygen occur for high temperature
Change and generate a large amount of clinkers, the incidental serious clinker of oxidation is excessive when preparing aerosolization iron sial, and easily stifled furnace, this is gas
The normal production of atomization iron sial causes to hinder.
Summary of the invention
The object of the present invention is to provide a kind of low-loss, high superposition 60 aerosolization iron sial powder of μ and magnetic core preparation methods.
The present invention by adding suitable additive and suitable smelting technology, aluminium vigorous oxidation when reducing high temperature to the greatest extent and formed big
Clinker is measured, avoids that stifled furnace occurs when atomization, can continuously prepare powder, after the powder sieving of preparation, simultaneously by the high temperature anneal
Insulating wrapped processing realizes 60 sendust core 100K/100mT of μ loss by compression moulding and high-temperature annealing process
500mW/cm3；It is superimposed performance 100Oe:85%；50Oe:95%.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of technique preparing iron sial powder using non-real air atomizing and make magnetic core, the technique the following steps are included:
1) major ingredient pure iron is taken, ferrosilicon, aluminum shot, auxiliary material is deslagging agent, carbon dust；
2) pure iron is put into intermediate frequency furnace, heated, soon melted completion to pure iron and be put into ferrosilicon, reduce frequency first after mixing evenly
Secondary fishing slag；
3) protective atmosphere gas curtain is opened after fishing out slag, pours into aluminum shot, quickly stirs and start thermometric, prepares atomization；
4) control of tundish initial temperature pours into molten steel and starts to be atomized at 1400 DEG C or more, keeps atomizing pressure；
5) it adjusts intermediate frequency furnace and Tundish Heating is kept for 1700 DEG C of molten steel temperature >, molten steel exposed part is formed during atomization and is protected
Protect atmosphere；6) sub-sieve is carried out to original powder after the completion of being atomized, rod milling and airflow milling is sold, sells rod milling again after nitrogen protection high annealing
It is stand-by that mixing is carried out afterwards；
7) it takes powder to carry out carrying out physical chemistry detection, the phosphoric acid solution being diluted with water is added；
8) iron aluminum silicon powder reacts in phosphoric acid solution, and the reaction time is 1-2 hours, after the reaction was completed in 80 DEG C~130 DEG C situations
Under be dried；
9) iron aluminum silicon powder is annealed 1-2 hours in n 2 annealing furnace high temperature again after phosphorating treatment, and temperature is higher than 500 DEG C；
10) high temperature resistant binder waterglass, potassium water glass, composite phosphate, SiO2 colloidal sol are added after the completion of the insulation of iron aluminum silicon powder
One or more of, additive amount is 0.5~2%；
11) zinc stearate is added after the completion of iron aluminum silicon powder insulation adhesive as lubricant, is mixed magnetic powder and is pressed into iron sial core magnetic
Core；
12) ferrocart core magnetic core is in N2Annealing heat-treatment is carried out under atmosphere；
13) magnetic core spray epoxy paint；
14) 500~450mW/cm is lost in the 026 sendust core 100K/100mT of μ to the preparation of top method3；It is superimposed performance
100Oe:61~63%；50Oe:80~83%.
Preferably, the mass fraction of each raw material is respectively as follows: major ingredient pure iron 80%~82%, ferrosilicon 9.5% in step 1)
~10%, aluminum shot 5%~6%, auxiliary material is deslagging agent 0.2 ‰, and carbon dust 0.5 ‰, surplus is inevitable impurity.
Preferably, the temperature of thermometric reaches 1750 DEG C~1800 DEG C in step 3), start to be atomized.
Preferably, keeping atomizing pressure in step 4) is 3.0Mpa.
Preferably, the additive amount of lubricant is the 0.2-0.5% of iron aluminum silicon powder in step 11), the pressure of compacting is
20T/cm3。
Preferably, the temperature being heat-treated in step 12) is 600-750 DEG C, when annealing Control for Oxygen Content 50ppm with
Under.
Preferably, in step 13) epoxy resin coating with a thickness of 0.3-0.5mm.
The beneficial effects of the present invention are: the present invention is subtracted as far as possible by adding suitable additive and suitable smelting technology
Aluminium vigorous oxidation when few high temperature and form a large amount of clinkers, avoid that stifled furnace occurs when atomization, can continuously prepare powder, the powder of preparation
After sieving, is handled by the high temperature anneal and insulating wrapped, by compression moulding and high-temperature annealing process, realize 60 iron of μ
500mW/cm is lost in sial magnetic core 100K/100mT3；It is superimposed performance 100Oe:63%；50Oe:83%.
