The Mix Up Problem

Occurs at all in transfer points
  • Pre wash to Austenitising Furnace

  • Furnace to Quench tank

  • Quench tank to Post wash

  • Post wash to Temper

  • Solution

    Components should not "see" any moving parts during transfer
    The design of the receiving equipment should prohibit retention

    1) Empty tanks
    • Prewash cum metering
    • Quench
    • Postwash
    • Agitators & jet spray nozzles removed for better viewing

    2) A batch of Needle Rollers are dumped into the tank, normally filled with relevant liquid. Capacity adjusted by varying the conveyor speed.

    3) No stragglers!!
    Zero retention & part mix up.
