1. The preparation method of the most new and effective reduced iron granular filler, it is characterized in that:

  • step one;

    the selection of raw material, select the raw material of following percentage by weight;

    70%~

    80% iron powder, 6%~

    10% bronze medal and the mixture of copper chloride, 5%~

    15% manganese dioxide, 3%~

    5% graphite powder, 1%~

    2% mixture of zinc and zinc chloride;

    Step 2;

    the process of raw material, takes the iron powder in step one raw material, crosses 100 mesh sieves, then taking manganese dioxide, pulverizing is milled, and crosses 100 mesh sieves, take graphite, pulverizing is milled, and crosses 100 mesh sieves, takes zinc powder and zinc chloride, wherein zinc powder is 1;

    3 with the weight ratio of zinc chloride, pulverize respectively and mill, cross 100 mesh sieves, be sufficiently mixed uniformly;

    Taking copper powder and copper chloride, wherein copper powder is 8;

    1 with the weight ratio of copper chloride, pulverizes respectively and mills, cross 100 mesh sieves, is sufficiently mixed uniformly;

    Step 3;

    material of pulverizing all of in step 2 being milled is mixed together uniformly, it is that 12;

    1 uniformly sprays 8% potassium hydroxide solution in compound by compound and potassium hydroxide solution mass ratio, then molding, drying, interim high-temperature firing, cooling 6-8 hour, pulverize and sieve and obtain product after process.
