1. a kind of medium-high frequency preparation method of high silicon steel soft magnet core, it is characterised in that using rapid solidification get rid of band method prepare it is highSilicon steel thin belt, is also not coated by insulating coating without Overheating Treatment afterwards, directly strikes out medium-high frequency electric machine iron core shape and is foldedPiece, or be directly wound into annular shape and be used as medium/high frequency transformer or medium-high frequency inductor core;

  • Getting rid of the specific technological process of high silicon steel thin belt for preparing 0.02-0.06mm thickness with method is:

    (1) raw material prepares:

    With ingot iron, crystalline silicon as raw material, in the ratio that silicone content is 5~

    8wt.% proportioning is carried out;

    WorkIndustry pure iron:

    Iron content 99.5%, crystalline silicon purity is 99.9%;

    (2) rapid solidification gets rid of band:

    Raw material is carried out plus hot smelting, under the fused solution that the degree of superheat is 50~

    250 DEG C, roller speed is10m/s~

    50m/s, using band method is got rid of by its rapid solidification, obtains high silicon steel thin belt of the thickness in 0.02-0.06mm.
