Features

Maruya Industry Co., Ltd. is the only electrode-specialist manufacturer in Japan to import high-quality raw materials for graphite electrodes from China and India for socket and nipple screw-cutting processing.

    • Applications: DC furnaces, AC furnaces, LF, etc.
    • Size: Diameter: 3”-22”, Length: 30”-96”
    • Features: Reduced risk of accidents relating to connectors by high-precision screw processing, abundant stock, processing matched to customer specifications (hollow processing also possible: up to 1,500mm)
       

    Fine processing precision guarantees high durability.
    To maintain the quality of synthetic graphite electrodes, Maruya Industry Co., Ltd. applies high-precision processing to achieve pole and nipple contact resistance. Maruya Industry Co., Ltd. offers stable supply of products capable of withstanding high levels of vibration by consumption control.

    Effect

    Centering

    Set on vibration stopper only

    All units

    High-precision centering prevents center misalignment during connection.

    Process time inspection

    Random

    All units

    Processing errors inevitably occur even if high-precision processing machines are used. It is preferable to inspect all units in order to reduce error as much as possible.

    Preset

    Manual tightening

    Tightened by torque wrench

    Carrying out appropriate torque presetting reduces the chance of nipple loosening.

    Shipping inspection

    Random

    All units

    Inspection of all units ensures that processing error and presetting unevenness can be checked thereby avoiding shipment of defective products.

    Blade replacement

    Irregular

    Regular

    Regular replacement of blades prevents screw precision defects caused by blade abrasion.

    Interdigitation inspection

    Not carried out

    Regular

    Regular checks of taper angles and screw interdigitation enable preemptive prevention of defects.
