  • Hardness testing machine (UKT)
  • Dimensional measurement unit (UKG)
  • Washing unit (UM)
  • Surface treatment unit (UPP)
  • Ultrasound testing unit (UUZK)
  • Magnet fluorescent inspection unit (UMKK)
  • Shot-blasting machine (UDO)
  • Stamping machine (UNK)
  • Painting and drying machine (UPK)
  • Labeling machine (UNE)
  • Transportation equipment

Goals of FIL Development

The main goal is development, manufacturing and introduction into commercial operation of automated FIL consisting of modern components and providing the following:

  • Quality enhancement for manufactured railroad wheels
  • Increase of  production of railroad wheels with enhanced wear resistance
  • Full automation of acceptance testing of railroad wheels:
    -  Washing and drying of railroad wheels
    -  Transportation of wheels through process area (un-stacking, tilting, stacking or putting wheels into cassettes, gathering of discarded wheels into stacks)
    -  Checking wheels disbalance
    -  Checking dimensional parameters of railroad wheels
    -  Checking hardness at of  rim edge of the wheel,
    -  Visual checking of surface defects
    -  Ultrasound inspection of internal defects
    -  Magnet fluorescent inspection of wheel surface
    -  Shot blasting unit for wheel hardening
    -  Applying of anti-corrosion protective painting
    -  Applying diameter value on the wheel surface
    -  Putting marking on the wheel surface
  • Information support with generating full data sheets, recording all parameters and features of the wheel (painting, shot blasting, internal structure etc)
  • Automatic control of parameters, providing regular operation mode of FIL
  • Routine collection, processing, transfer and storage of data on the state of FIL process equipment
  • Displaying of parameters, reflecting the process progress and provision of servicing personnel with actual data about failures in operation of FIL equipment
  • Remote automated and automatic control over process equipment.
