Device Summary

  • Operability and safety have been improved compared to the traditional vacuum carburizing device. New operational software has been developed for the purpose of energy conservation, and the selection of optimal conditlons has been simplified.
  • Advance maintenance notification system is equipped on all the devices.
  • The greatest characteristic is the carburizing process time. The cycle duration, which starts from heating to oil quenching, has been shortened by 30 to 45 min compared to the conventional vacuum carburizing device.
  • Consistent operationg conditions and carburizing duration can be ensured by a unique structure.

Device Summary

  • Two chambers with the internal seal door allow both oil and gas quench at the quenching chamber.
  • Servomotor enables higher quality of oil quench, shorter time in the quench tank (1 sec) and high-speed swing.
  • By avoiding cooling down during each cooling process, it cuts costs for reheating the heating chamber.
  • The heating chamber is always kept free from contacts with the atmosphere for the ideal no oxygen process. Additionally, thanks to vacuum heating without significant pressure change, insulating materials last longer.
