Abstract
The invention relates to a method for producing alloy soft magnetic powder corn, which can improve density, magnetic conductivity and Q value, wherein it comprises that: smelting master alloy, ejecting alloy band, embrittling at 200-600Deg. C, grinding magnetic powder, packing said magnetic powder, compressing, thermally treating, plating the outer layer of magnetic corn or dipping paint.
Description
The present invention relates to a kind of manufacture method of magnetic bodies, relate in particular to a kind of alloy soft magnetic powder core production method that is used to make inductive element
Existing is that the method for material preparation magnetic core generally is with the alloy: with the direct powder by spraying of molten condition alloy, also can make band powder process more earlier for amorphous, nanometer crystal alloy, use organic epoxy resin glue bond compression moulding again.The magnetic core that this method is made, density is poor, the magnetic conductivity of powder core performance indications such as (generally in 150) are low, and magnetic core intensity is relatively poor.
The present invention is directed to the defective that above-mentioned prior art exists, the alloy soft magnetic powder core production method of performance indications excellences such as a kind of density, magnetic conductivity and Q value is provided.
Technical scheme of the present invention comprises the steps: smelting nut alloy, and------The pre-heat treatment---is ground the preparation magnetic---with binding agent insulation parcel magnetic powder particle---outer spraying of compression moulding---heat treatment---magnetic core or dipping lacquer parcel to the spray of alloy band (sheet) material, described The pre-heat treatment is that embrittlement in 0.5-5 hour is handled under 200-600 ℃ of temperature, described band comprises other alloy strip steel rolled stocks such as amorphous, nanocrystalline or sloping film alloy, and described heat treatment is to handle through two sections heat preservation hot of 200-220 ℃, 0.5-2 hour and 400-565 ℃, 0.5-3 hour respectively.
Before the compression moulding,, carry out compression moulding again after the proportioning with the raw material of different types of identical or different fineness.
Described grinding flour is the grinding of carrying out under the protection of inert gas 1-10 hour, and its grain fineness is the 50-600 order.
Described two sections heat treated temperature and times of insulation are respectively: first section 220 ℃, 0.5 hour, and second section 565 ℃, 3 hours.
Described binding agent addition is the 0.5-30% of magnetic weight portion.
Alloy soft magnetic powder core production method of the present invention is that earlier involutory gold ribbon (sheet) material carries out heat-treating after broken powder process after the The pre-heat treatment embrittlement, batching, parcel, the compression moulding again, and adopt two sections insulations, can eliminate Stress in Magnetic Core, gain in strength and density, improved the magnetic conductivity (generally can reach more than 150) of magnetic core, optimize comprehensive magnetic parameter, guarantee the uniformity of particular product performance parameters, also can make powder process again behind band or the sheet material earlier for other alloy material beyond the amorphous nano peritectic alloy.
Below in conjunction with embodiment technical solution of the present invention is described further.
Vacuum melting furnace is smelted the linear velocity spray amorphous alloy strip steel rolled stock of FeCuNbSiB foundry alloy with 20-32m/s, the embrittlement that this alloy strip steel rolled stock carried out under 230 ℃ temperature 1 hour is handled; To be somebody's turn to do after the amorphous alloy strip steel rolled stock after the The pre-heat treatment grinds 1 hour with horizontal ball mill under the protection of inert gas, the three kinds of fineness of 150,250 and 300 orders of looking over so as to check respectively, be respectively 30%, 30% and 40% proportioning by weight, add 12% binding agent again, stirred 0.5 hour; To be needed magnetic core with the pressure compression moulding of 400MPa through the particle behind the parcel; Adopt two sections thermal-insulating methods to carry out crystallization and thermal treatment under the protection of inert gas in the magnetic core after the described moulding, the temperature and time of its two sections insulations is respectively: first section 220 ℃, 0.5 hour, and second section 565 ℃, 3 hours.After two sections insulations finish, stop heating and cool to below 100 ℃ the heat treatment process end with the furnace; Magnetic core after the heat treatment makes the magnetic core outer surface form thin film by the method for dipping lacquer or spraying insulation.
The outfit of magnetic can be according to the different requirements of designed magnetic core performance index, its magnetic fineness can be respectively 100,200,300,400 or 500 single orders, or wherein the raw material of several fineness is equipped with according to a certain percentage, simultaneously can also carry out mixed preparing, as adding metal or alloy fine powders such as pure iron, nickel with the raw material of unlike material.
