1. the technique that a kind of waste and old beam hanger remanufactures, which is characterized in that include the following steps:

  • Step 1:

    SortingIt is sorted by rank, specification;

    Rank is divided into three classes according to D, HY, HL, and specification is divided according to φ

    16, φ

    19, φ

    22, φ

    25For four classes;

    Step 2:

    PretreatmentUsing hot water, carbonization scale removal, mechanical derusting;

    Waste and old head is dispelled with sawing machine;

    Spectrometer is selected to waste and old sucker rodMaterial carries out material classification and determines;

    Surface derusting is carried out with shot-blast apparatus, removes impurity, and metal true qualities are exposed on body of rod surface 100%;

    Step 3:

    Hot rollingThe body of rod is subjected to the body of rod hot rolling by hot-rolling mill, temperature is controlled at 940-1060 DEG C;

    Step 4:

    Flaw detectionThe round steel after hot rolling is detected by magnetic flux leakage testing device;

    Magnetic leakage detection should meet the related request of GB/T 12606,Residual magnetism should be less than 30GS after demagnetization;

    Step 5:

    ForgingClosed die forging is carried out to the body of rod using horizontal forging and upsetting machine, so as to obtain the size shape needed for processing screw thread;

    Step 6:

    It is quenched840-880 DEG C is heated to by cabinet-type electric furnace to the body of rod uniformly to be quenched, using 640-660 DEG C of tempering;

    Step 7:

    Post-processingShot Blasting is carried out to the body of rod after quenched with shot-blast apparatus;

    Again screw thread process is carried out with numerical control screw thread milling machine;

    Again to spiral shellThe body of rod after line processing carries out box cupling and assembles to get the sucker rod to after remanufacturing.
