1. a preparation method for noncrystalline soft magnetic core, is characterized in that, comprising:

  • The Fe class amorphous metal band prepared by quick setting method is carried out to the step of the pre-heat treatment;

    The step obtaining amorphous metal powder is pulverized to above-mentioned amorphous metal band;

    After classification is carried out to above-mentioned amorphous metal powder, with make particle size distribution reach 75 ~ 100 μ

    m;

    10 ~ 85 percentage by weights, 50 ~ 75 μ

    m;

    10 ~ 70 percentage by weights, 5 ~ 50 μ

    m;

    5 ~ 20 percentage by weights mode amorphous metal powder is mixed to the step obtaining mixed-powder;

    Binding agent is added at above-mentioned mixed-powder, and by the shaping step obtaining form forming magnetic core body;

    AndAfter carrying out annealing in process to above-mentioned form forming magnetic core body, coating insulating resin obtains the step of soft magnetic core.
